-<h3 id="tut-chapter-introduction">Introduction</h3>
-<div class="paragraph">
-<p>The topic is modeling of the operation of (manufacturing) systems, e.g.
-semiconductor factories, assembly and packaging lines, car manufacturing
-plants, steel foundries, metal processing shops, beer breweries, health care
-systems, warehouses, order-picking systems.
-For a proper functioning of these systems, these systems are controlled by
-operators and electronic devices, e.g. computers.</p>
-</div>
-<div class="paragraph">
-<p>During the design process, engineers make use of (analytical) mathematical
-models, e.g. algebra and probability theory, to get answers about the
-operation of the system.
-For complex systems, (numerical) mathematical models are used, and computers
-perform simulation experiments, to analyze the operation of the system.
-Simulation studies give answers to questions like:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>What is the throughput of the system?</p>
-</li>
-<li>
-<p>What is the effect of set-up time in a machine?</p>
-</li>
-<li>
-<p>How will the batch size of an order influence the flow time of the
-product-items?</p>
-</li>
-<li>
-<p>What is the effect of more surgeons in a hospital?</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>
-
-The operation of a system can be described, e.g. in terms of or operating
-processes.</p>
-</div>
-<div class="paragraph">
-<p>An example of a system with parallel operating processes is a manufacturing
-line, with a number of manufacturing machines, where product-items go from
-machine to machine.
-A surgery room in a hospital is a system where patients are treated by teams
-using medical equipment and sterile materials.
-A biological system can be described by a number of parallel processes, where,
-e.g. processes transform sugars into water and carbon-dioxide producing
-energy.
-In all these examples, processes operate in parallel to complete a task, and
-to achieve a goal.
-Concurrency is the dominant aspect in these type of systems, and as a
-consequence this holds too for their models.</p>
-</div>
-<div class="paragraph">
-<p>The operating behavior of parallel processes can be described by different
-formalisms, e.g. automata, Petri-nets or parallel processes. This text uses
-the programming language Chi, which is an instance of a parallel processes
-formalism.</p>
-</div>
-<div class="paragraph">
-<p>A system is abstracted into a model, with cooperating processes, where
-processes are connected to each other via channels.
-The channels are used for exchanging material and information.
-Models of the above mentioned examples consist of a number of concurrent
-processes connected by channels, denoting the flow of products, patients or
-personnel.</p>
-</div>
-<div class="paragraph">
-<p>In Chi, communication takes place in a synchronous manner.
-This means that communication between a sending process, and a receiving
-process takes place only when both processes are able to communicate.
-Processes and channels can dynamically be altered.
-To model times, like inter-arrival times and server processing times, the
-language has a notation of time.</p>
-</div>
-<div class="paragraph">
-<p>The rationale behind the language is that models for the analysis of a system should be</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>formal (exactly one interpretation, every reader attaches the same meaning to the model),</p>
-</li>
-<li>
-<p>easily writable (write the essence of the system in a compact way),</p>
-</li>
-<li>
-<p>easily readable (non-experts should be able to understand the model),</p>
-</li>
-<li>
-<p>and easily extensible (adding more details in one part should not affect other parts).</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>Verification of the models to investigate the properties of the model should
-be relatively effortless. (A model has to preserve some properties of the real system
-otherwise results from the simulation study have no relation with the system
-being modeled. The language must allow this verification to take place in a
-simple manner.)</p>
-</div>
-<div class="paragraph">
-<p>Experiments should be performed in an straightforward manner. (Minimizing the
-effort in doing simulation studies, in particular for large systems, makes the
-language useful.)</p>
-</div>
-<div class="paragraph">
-<p>Finally, the used models should be usable for the supervisory (logic) control
-of the systems (simulation studies often provide answers on how to control a
-system in a better way, these answers should also work for the modeled
-system).</p>
-</div>
-<div class="sect3">
-<h4 id="tut-chi-in-a-nutshell">Chi in a nutshell</h4>
-<div class="paragraph">
-<p>During the past decades, the ancestors of Chi have been used with success,
-for the analysis of a variety of (industrial) systems.
-Based on this experience, the language Chi has been completely redesigned,
-keeping the strong points of the previous versions, while making it more
-powerful for advanced users, and easier to access for non-experts.</p>
-</div>
-<div class="paragraph">
-<p>Its features are:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>A system (and its control) is modeled as a collection of parallel running
-processes, communicating with each other using channels.</p>
-</li>
-<li>
-<p>Processes do not share data with other processes and channels are
-synchronous (sending and receiving is always done together at the same
-time), making reasoning about process behavior easier.</p>
-</li>
-<li>
-<p>Processes and channels are dynamic, new processes can be created as needed,
-and communication channels can be created or rerouted.</p>
-</li>
-<li>
-<p>Variables can have elementary values such as <em>boolean</em>, <em>integer</em> or <em>real</em>
-numbers, to high level structured collections of data like <em>lists</em>, <em>sets</em>
-and <em>dictionaries</em> to model the data of the system. If desired, processes
-and channels can also be part of that data.</p>
-</li>
-<li>
-<p>A small generic set of statements to describe algorithms, assignment, <em>if</em>,
-<em>while</em>, and <em>for</em> statements. This set is relatively easy to explain to
-non-experts, allowing them to understand the model, and participate in the
-discussions.</p>
-</li>
-<li>
-<p>Tutorials and manuals demonstrate use of the language for effective modeling
-of system processes. More detailed modeling of the processes, or custom
-tailoring them to the real situation, has no inherent limits.</p>
-</li>
-<li>
-<p>Time and (quasi-) random number generation distributions are available for
-modeling behavior of the system in time.</p>
-</li>
-<li>
-<p>Likewise, measurements to derive performance indicators of the modeled
-system are integrated in the model. Tutorials and manuals show basic use.
-The integration allows for custom solutions to obtain the needed data in the
-wanted form.</p>
-</li>
-<li>
-<p>Input and output facilities from and to the file system exists to support
-large simulation experiments.</p>

-<h3 id="tut-chapter-data-types">Data types</h3>
-<div class="paragraph">
-<p>The language is a statically typed language, which means that all variables
-and values in a model have a single fixed type.
-All variables must be declared in the program.
-The declaration of a variable consists of the type, and the name, of the
-variable. The following fragment shows the declaration of two elementary data
-types, integer variable <code>i</code> and real variable <code>r</code>:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">...
-int i;
-real r;
-...</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The ellipsis (<code>...</code>) denotes that non-relevant information is left out from
-the fragment. The syntax for the declaration of variables is similar to the
-language <em>C</em>. All declared variables are initialized, variables <code>i</code> and
-<code>r</code> are both initialized to zero.</p>
-</div>
-<div class="paragraph">
-<p>An expression, consisting of operators, e.g. plus (<code>+</code>), times (<code>*</code>), and
-operands, e.g. <code>i</code> and <code>r</code>, is used to calculate a new value. The new
-value can be assigned to a variable by using an <em>assignment</em> statement. An
-example with four variables, two expressions and assignment statements is:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">...
-int i = 2, j;

-
-j = 2 * i + 1;
-s = r / 2;
-...</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The value of variable <code>j</code> becomes <code>5</code>, and the value of <code>s</code> becomes
-<code>0.75</code>.
-Statements are described in <a href="#tut-chapter-statements">Statements</a>.</p>
-</div>
-<div class="paragraph">
-<p>Data types are categorized in five different groups: <em>elementary</em> types,
-<em>tuple</em> types, <em>container</em> types, <em>custom</em> types, and <em>distribution</em> types.
-Elementary types are types such as Boolean, integer, real or string.
-Tuple types contain at least one element, where each element can be of
-different type. In other languages tuple types are called records (Pascal) or
-structures (C).
-Variables with a container type (a list, set, or dictionary) contain many
-elements, where each element is of the same type.
-Custom types are created by the user to enhance the readability of the model.
-Distributions types are types used for the generation of distributions from
-(pseudo-) random numbers.
-They are covered in <a href="#tut-chapter-stochastic-behavior">Modeling stochastic behavior</a>.</p>

-Elements can be added or removed in variables of these types.

-<div class="paragraph">
-<p>Sets are unordered collections of elements. Each element value either exists
-in a set, or it does not exist in a set.
-Each element value is unique, duplicate elements are silently discarded.
-A list is an ordered collection of elements, that is, there is a first and a last
-element (in a non-empty list). A list also allows duplicate element values.
-Dictionaries are unordered and have no duplicate value, just like sets, but
-you can associate a value (of a different type) with each element value.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-Lists are denoted by a pair of (square) brackets.
-For example, <code>[7, 8, 3]</code> is a list with three integer elements. Since a list
-is ordered, <code>[8, 7, 3]</code> is a different list.
-With empty lists, the computer has to know the type of the elements, e.g.
-<code><int>[]</code> is an empty list with integer elements.
-The prefix <code><int></code> is required in this case.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-Sets are denoted by a
-pair of (curly) braces, e.g. <code>{7, 8, 3}</code> is a set with three integer
-elements.
-As with lists, for an empty set a prefix is required, for example
-<code><string>{}</code> is an empty set with strings.
-A set is an unordered collection of elements.
-The set <code>{7, 8, 3}</code> is a set with three integer numbers. Since order of
-the elements does not matter, the same set can also be written as
-<code>{8, 3, 7}</code> (or in one of the four other orders).
-In addition, each element in a set is unique, the set <code>{8, 7, 8, 3}</code> is
-equal to the set <code>{7, 8, 3}</code>.
-For readability, elements in a set are normally written in increasing order,
-for example <code>{3, 7, 8}</code>.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-Dictionaries are denoted by a pair of (curly) braces, whereby an element value
-consists of two parts, a 'key' and a 'value' part.
-The two parts separated by a colon (<code>:</code>).
-For example <code>{"jim" : 32, "john" : 34}</code> is a dictionary with two elements.
-The first element has <code>"jim"</code> as key part and <code>32</code> as value part, the
-second element has <code>"john"</code> as key part and <code>34</code> as value part.
-The key parts of the elements work like a set, they are unordered and
-duplicates are silently discarded. A value part is associated with its key
-part.
-In this example, the key part is the name of a person, while the value part
-keeps the age of that person.
-Empty dictionaries are written with a type prefix just like lists and sets,

-<div class="paragraph">
-<p>
-
-For sets, the first field of the tuple becomes the

-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">pop({8, 7, 3}) -> (7, {3, 8}) or

-<div class="paragraph">
-<p>
-
-Performing a <code>pop</code> on a dictionary
-follows the same pattern as above, except 'a value from the collection' are

-gives a three-tuple as result. The first field of the tuple becomes the key
-of the extracted element, the second field of the tuple becomes the value of
-the element, and the third field of the tuple contains the dictionary except

-The list of all but the first elements (<code>xs[1:]</code>) is often called <em>tail</em>

-Two lists can be 'glued' together into a new list.
-The glue-ing or concatenation of a list with elements <code>7</code>, <code>8</code>, <code>3</code> and a
-list with elements <code>5</code>, and <code>9</code> is denoted by:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">[7, 8, 3] + [5, 9] -> [7, 8, 3, 5, 9]</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>An element can be added to a list at the rear or at the front.
-The action is performed by transforming the element into a list and then
-concatenate these two lists. In the next example the value <code>5</code> is added to
-the rear, respectively the front, of a list:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">[7, 8, 3] + [5] -> [7, 8, 3, 5]
-[5] + [7, 8, 3] -> [5, 7, 8, 3]</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>
-
-
-
-
-
-Elements also can be removed from a list.
-The <code>del</code> function removes by position, e.g. <code>del(xs, 2)</code> returns the list
-<code>xs</code> without its third element (since positions start at index 0).
-Removing a value by value can be performed by the subtraction operator <code>-</code>.
-For instance, consider the following subtractions:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">[1, 4, 2, 4, 5] - [2] -> [1, 4, 4, 5]
-[1, 4, 2, 4, 5] - [4] -> [1, 2, 4, 5]
-[1, 4, 2, 4, 5] - [8] -> [1, 4, 2, 4, 5]</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Every element in the list at the right is searched in the list at the left,
-and if found, the <em>first</em> occurrence is removed.
-In the first example, element <code>2</code> is removed. In the second example, only
-the first value <code>4</code> is removed and the second value (at position 3) is kept.
-In the third example, nothing is removed, since value <code>8</code> is not in the list
-at the left.</p>
-</div>
-<div class="paragraph">
-<p>When the list at the right is longer than one element, the operation is repeated.
-For example, consider <code>xs - ys</code>, whereby <code>xs = [1, 2, 3, 4, 5]</code> and
-<code>ys = [6, 4, 2, 3]</code>. The result is computed as follows:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi"> [1, 2, 3, 4, 5] - [6, 4, 2, 3]
--> ([1, 2, 3, 4, 5] - [6]) - [4, 2, 3]
--> [1, 2, 3, 4, 5] - [4, 2, 3]
--> ([1, 2, 3, 4, 5] - [4]) - [2, 3]
--> [1, 2, 3, 5] - [2, 3]

-<p>Lists have two relational operators, the equal operator and the not-equal operator.
-The equal operator (<code>==</code>) compares two lists. If the lists have the same
-number of elements and all the elements are pair-wise the same, the result of
-the operation is <code>true</code>, otherwise <code>false</code>.
-The not-equal operator (<code>!=</code>) does the same check, but with an opposite result.

-<p>The union of two sets merges the values of both sets into one, that is, the

-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">y = x + 10</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This assignment consists of a name of the variable (<code>y</code>), an assignment
-symbol (<code>=</code>), and an expression (<code>x + 10</code>) yielding a value. For example,
-when <code>x</code> is <code>2</code>, the value of the expression is <code>12</code>.
-Execution of this statement copies the value to the <code>y</code> variable,
-immediately after executing the assignment, the value of the <code>y</code> variable is
-<code>10</code> larger than the value of the <code>x</code> variable at this point of the
-program.
-The value of the <code>y</code> variable will not change until the next assignment to
-<code>y</code>, for example, performing the assignment <code>x = 7</code> has no effect on the
-value of the <code>y</code> variable.</p>
-</div>
-<div class="paragraph">
-<p>An example with two assignment statements:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">i = 2;
-j = j + 1</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The values of <code>i</code> becomes 2, and the value of <code>j</code> is incremented.
-Independent assignments can also be combined in a multi-assignment, for
-example:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">i, j = 2, j + 1</code></pre>

-</div>
-<div class="paragraph">
-<p>To perform a different statement when the decision fails, an <code>if</code>-statement

-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">if a > 0:

-<div class="paragraph">
-<p>If <code>a</code> is positive, variable <code>c</code> gets the value of <code>a</code>, otherwise it
-gets the value of <code>b</code>.</p>
-</div>
-<div class="paragraph">
-<p>In some cases more alternatives must be tested. One way of writing it is by

-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">if i < 0:

- writeln("i >= 10")
- end
- end
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This tests <code>i < 0</code>. If it fails, the <code>else</code> is chosen, which contains a

-third condition <code>i > 0 and i < 10</code> is tested, and one of the <code>writeln</code>
-statements is chosen.</p>
-</div>
-<div class="paragraph">
-<p>The above can be written more compactly by combining an <code>else</code>-part and the
-<code>if</code>-statement that follows, into an <code>elif</code> part. Each <code>elif</code> part
-consists of a boolean expression, and a statement list. Using <code>elif</code> parts
-results in:</p>

-<div class="paragraph">
-<p>In a model, computations must be performed to process the information that is
-sent around.
-Short and simple calculations are written as assignments between the other
-statements, but for longer computations or computations that are needed at
-several places in the model, a more encapsulated environment is useful, a
-<em>function</em>.
-In addition, the language comes with a number of built-in functions, such as
-<code>size</code> or <code>empty</code> on container types.
-An example:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">func real mean(list int xs):
- int sum;
-
- for x in xs:
- sum = sum + x
- end;
- return sum / size(xs)
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The <code>func</code> keyword indicates it is a function. The name of the function is
-just before the opening parenthesis, in this example <code>mean</code>. Between the
-parentheses, the input values (the <em>formal parameters</em>) are listed. In this
-example, there is one input value, namely <code>list int</code> which is a list of
-integers. Parameter name <code>xs</code> is used to refer to the input value in the
-body of the function.
-Between <code>func</code> and the name of the function is the type of the computation
-result, in this case, a <code>real</code> value.
-In other words, this <code>mean</code> function takes a list of integers as input, and
-produces a <code>real</code> value as result.</p>
-</div>
-<div class="paragraph">
-<p>
-
-The colon at the end of the first line indicates the start of the computation.
-Below it are new variable declarations (<code>int sum</code>), and statements to
-compute the value, the <em>function algorithm</em>.
-The <code>return</code> statement denotes the end of
-the function algorithm.
-The value of the expression behind it is the result of the calculation.
-This example computes and returns the mean value of the integers of the list.</p>
-</div>
-<div class="paragraph">
-<p>Use of a function (<em>application</em> of a function) is done by using its name,
-followed by the values to be used as input (the <em>actual parameters</em>).
-The above function can be used like:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">m = mean([1, 3, 5, 7, 9])</code></pre>

-</div>
-<div class="paragraph">
-<p>The actual parameter of this function application is <code>[1, 3, 5, 7, 9]</code>.
-The function result is <code>(1 + 3 + 5 + 7 + 9)/5</code> (which is <code>5.0</code>), and
-variable <code>m</code> becomes <code>5.0</code>.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-A function is a mathematical function: the result of a function is the same
-for the same values of input parameters.
-A function has no <em>side-effect</em>, and it cannot access variables outside the body.
-For example, it cannot access <code>time</code> (explained in

-<h4 id="tut-sorted-lists">Sorted lists</h4>
-<div class="paragraph">
-<p>The language allows <em>recursive</em> functions as well as <em>higher-order</em> functions.
-Explaining them in detail is beyond the scope of this tutorial, but these
-functions are useful for making and maintaining sorted lists.
-Such a sorted list is useful for easily getting the smallest (or largest) item
-from a collection, for example the order with the nearest deadline.</p>
-</div>
-<div class="paragraph">
-<p>To sort a list, the first notion that has to be defined is the desired order,
-by making a function of the following form:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">func bool decreasing(int x, y):
- return x >= y
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The function is called <em>predicate function</em>.
-It takes two values from the list (two integers in this case), and produces a
-boolean value, indicating whether the parameters are in the right order.
-In this case, the function returns <code>true</code> when the first parameter is larger
-or equal than the second parameter, that is, larger values must be before
-smaller values (for equal values, the order does not matter). This results in
-a list with decreasing values.</p>
-</div>
-<div class="paragraph">
-<p>The requirements on <em>any</em> predicate function <code>f</code> are:</p>
-</div>
-<div class="olist arabic">
-<ol class="arabic">
-<li>
-<p>If <code>x != y</code>, either <code>f(x, y)</code> must hold or <code>f(y, x)</code> must hold, but
-not both. (Unequal values must have a unique order.)</p>
-</li>
-<li>
-<p>If <code>x == y</code>, both <code>f(x, y)</code> and <code>f(y, x)</code> must hold. (Equal values
-can be placed in arbitrary order.)</p>
-</li>
-<li>
-<p>For values <code>x</code>, <code>y</code>, and <code>z</code>, if <code>f(x, y)</code> holds and <code>f(y, z)</code>
-holds (that is <code>x >= y</code> and <code>y >= z</code>), then <code>f(x, z)</code> must also hold
-(that is, <code>x >= z</code> should also be true).</p>
-</li>
-</ol>
-</div>
-<div class="paragraph">
-<p>(The order between <code>x</code> and <code>z</code> must be stable, even when you compare
-with an intermediate value <code>y</code> between <code>x</code> and <code>z</code>.)</p>
-</div>
-<div class="paragraph">
-<p>These requirements hold for functions that test on <code><=</code> or <code>>=</code> between
-two values, like above.</p>
-</div>
-<div class="paragraph">
-<p>If you do not provide a proper predicate function, the result may not be

-<h5 id="tut-sort">Sort</h5>
-<div class="paragraph">
-<p>The first use of such a predicate function is for sorting a list. For example
-list <code>[3, 8, 7]</code> is sorted decreasingly (larger numbers
-before smaller numbers) with the following statement:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">ys = sort([3, 8, 7], decreasing)</code></pre>

-<div class="paragraph">
-<p>Sorting is done with the <em>sort</em> function, it takes two parameters, the list to
-sort, and the predicate <em>function</em>. (There are no parentheses <code>()</code> behind
-<code>decreasing</code>!) The value of list <code>ys</code> becomes <code>[8, 7, 3]</code>.</p>
-</div>
-<div class="paragraph">
-<p>Another sorting example is a list of type <code>tuple(int number, real slack)</code>,
-where field <code>number</code> denotes the number of an item, and field <code>slack</code>
-denotes the slack time of the item. The list should be sorted in ascending
-order of the slack time. The type of the item is:</p>

-is very expensive.
-It is much faster to find the right position in the already sorted list, and
-insert the new value at that point.
-This function also exists, and is named <code>insert</code>.

-<h4 id="tut-the-write-statement">The <code>write</code> statement</h4>
-<div class="paragraph">
-<p>The <em>write</em> statement is used for for output of data to the screen of the
-computer. Data can also be written to a file.</p>
-</div>
-<div class="paragraph">
-<p>The first argument of <code>write</code> (or the second argument if you write to a file,
-see below) Is called the <em>format string</em>. It is a template of the text to
-write, with 'holes' at the point where a data value is to be written.</p>
-</div>
-<div class="paragraph">
-<p>Behind the format string, the data values to write are listed. The first value is
-written in the first 'hole', the second value in the second 'hole' and so
-on. The holes are also called <em>place holders</em>. A place holder starts with
-<code>%</code> optionally followed by numbers or some punctuation (its meaning is
-explained below). A place holder ends with a <em>format specifier</em>, a single
-letter like <code>s</code> or <code>f</code>. An example:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">int i = 5;
-
-write("i equals %s", i)</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>In this example the text <code>i equals 5</code> is written to the screen by the
-<code>write</code> statement. The <code>"i equals %s"</code> format string defines what output
-is written. All 'normal' characters are copied as-is. The <code>%s</code> place holder
-is not copied. Instead the first data value (in this case <code>i</code>) is inserted.</p>
-</div>
-<div class="paragraph">
-<p>The <code>s</code> in the place holder is the format specifier. It means 'print as
-string'. The <code>%s</code> is a general purpose format specifier, it works with
-almost every type of data. For example:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">list dict(int:real) xs = [{1 : 5.3}];
-
-write("%s", xs)</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>will output the contents of <code>xs</code> (<code>{1 : 5.3}</code>).</p>
-</div>
-<div class="paragraph">
-<p>In general, this works nicely, but for numeric values a little more control
-over the output is often useful.
-To this end, there are also format specifiers <code>d</code> for integer numbers, and
-<code>f</code> for real numbers.
-An example:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">int i = 5;
-real r = 3.14;
-
-write("%4d/%8.2f", i, r)</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This fragment has the effect that the values of <code>i</code> and <code>r</code> are written to
-the screen as follows:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console"> 5/ 3.14</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The value of <code>i</code> is written in <code>d</code> format (as <code>int</code> value), and the
-value of <code>r</code> is written in <code>f</code> format (as <code>real</code> value).
-The symbols <code>d</code> and <code>f</code> originate respectively from 'decimal', and
-'floating point' numbers.
-The numbers <code>4</code> respectively <code>8.2</code> denote that the integer value is
-written four positions wide (that is, 3 spaces and a <code>5</code> character), and
-that the real value is written eight positions wide, with two characters after
-the decimal point (that is, 4 spaces and the text <code>3.14</code>).</p>

-Many processes in the world vary a little bit each time they are performed.
-Setup of machines goes a bit faster or slower, patients taking their medicine
-takes longer this morning, more products are delivered today, or the quality

-Modeling such variations is often done with stochastic distributions. A

-A continuous distribution is a distribution where a value from a continuous

-One solution is to first write a model without stochastic behavior, verify
-that model, and then extend the model with stochastic sampling.
-Extending the model with stochastic behavior is however an invasive change
-that may introduce new errors. These errors are again hard to find due to the

-distributions are replaced with the distributions that fit the mean value and

-<div class="paragraph">
-<p>In this chapter, the mathematical notion of stochastic distribution is used to
-describe how to model stochastic behavior.
-Simulating a model with stochastic behavior at a computer is however not
-stochastic at all. Computer systems are deterministic machines, and
-have no notion of varying results.</p>
-</div>
-<div class="paragraph">
-<p>A (pseudo-)random number generator is used to create stochastic results
-instead. It starts with an initial <em>seed</em>, an integer number (you can give one
-at the start of the simulation).
-From this seed, a function creates a stream of 'random' values. When looking
-at the values there does not seem to be any pattern.
-It is not truly random however. Using the same seed again gives exactly the
-same stream of numbers. This is the reason to call the function a
-<em>pseudo</em>-random number generator (a true random number generator would never
-produce the exact same stream of numbers).
-A sample of a distribution uses one or more numbers from the stream to compute
-its value.
-The value of the initial seed thus decides the value of all samples drawn in
-the simulation. By default, a different seed is used each time you run a
-simulation (leading to slightly different results each time).
-You can also explicitly state what seed you want to use when running a model,
-see <a href="#tool-compile-and-simulate">Compile and simulate</a>.
-At the end of the simulation, the used
-initial seed of that simulation is printed for reference purposes.</p>
-</div>
-<div class="paragraph">
-<p>While doing a stochastic simulation study, performing several experiments with
-the same initial seed invalidates the results, as it is equivalent to copying
-the outcome of a single experiment a number of times.
-On the other hand, when looking for the cause of a bug in the model,
-performing the exact same experiment is useful as outcomes of previous
-experiments should match exactly.</p>

-The language has been designed for modeling and analyzing systems with many
-components, all working together to obtain the total system behavior.
-Each component exhibits behavior over time. Sometimes they are busy making
-internal decisions, sometimes they interact with other components.
-The language uses a <em>process</em> to model the behavior of a component (the
-primary interest are the actions of the component rather than its physical
-representation). This leads to models with many processes working in
-<em>parallel</em> (also known as <em>concurrent</em> processes), interacting with each
-other.</p>
-</div>
-<div class="paragraph">
-<p>Another characteristic of these systems is that the parallelism happens at
-different scales at the same time, and each scale can be considered to be a
-collection of co-operating parallel working processes.
-For example, a factory can be seen as a single component, it accepts supplies
-and delivers products.
-However, within a factory, you can have several parallel operating production
-lines, and a line consists of several parallel operating machines.
-A machine again consists of parallel operating parts.
-In the other direction, a factory is a small element in a supply chain. Each
-supply chain is an element in a (distribution) network.
-Depending on the area that needs to be analyzed, and the level of detail, some
-scales are precisely modeled, while others either fall outside the scope of
-the system or are modeled in an abstract way.</p>
-</div>
-<div class="paragraph">
-<p>In all these systems, the interaction between processes is not random, they
-understand each other and exchange information.
-In other words, they <em>communicate</em> with each other. The Chi language uses
-<em>channels</em> to model the communication.
-A channel connects a sending process to a receiving process, allowing the
-sender to pass messages to the receiver.
-This chapter discusses parallel operating processes only, communication
-between processes using channels is discussed in <a href="#tut-chapter-channels">Channels</a>.</p>
-</div>
-<div class="paragraph">
-<p>As discussed above, a process can be seen as a single component with behavior
-over time, or as a wrapper around many processes that work at a smaller scale.
-The Chi language supports both kinds of processes.
-The former is modeled with the statements explained in previous chapters and
-communication that will be explained in <a href="#tut-chapter-channels">Channels</a>.
-The latter (a process as a wrapper around many smaller-scale processes) is
-supported with the <code>run</code> statement.</p>
-</div>
-<div class="sect3">
-<h4 id="tut-a-single-process">A single process</h4>
-<div class="paragraph">
-<p>The simplest form of processes is a model with one process:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">proc P():
- write("Hello. I am a process.")
-end
-
-model M():
- run P()
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Similar to a model, a process definition is denoted by the keyword <code>proc</code>
-(<code>proc</code> means process and does not mean procedure!), followed by the name of
-the process, here <code>P</code>, followed by an empty pair of parentheses <code>()</code>,
-meaning that the process has no parameters.
-Process <code>P</code> contains one statement, a <code>write</code> statement to output text to
-the screen.
-Model <code>M</code> contains one statement, a <code>run</code> statement to run a process.
-When simulating this model, the output is:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">Hello. I am a process.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>
-
-A <code>run</code> statement constructs a process from the process definition (it
-<em>instantiates</em> a process definition) for each of its arguments, and they start
-running.
-This means that the statements inside each process are executed. The <code>run</code>
-statement waits until the statements in its created processes are finished,
-before it ends itself.</p>
-</div>
-<div class="paragraph">
-<p>To demonstrate, below is an example of a model with two processes:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">proc P(int i):
- write("I am process. %d.\n", i)
-end
-
-model M():
- run P(1), P(2)
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This model instantiates and runs two processes, <code>P(1)</code> and <code>P(2)</code>.
-The processes are running at the same time.
-Both processes can perform a <code>write</code> statement.
-One of them goes first, but there is no way to decide beforehand which one.
-(It may always be the same choice, it may be different on Wednesday, etc, you
-just don’t know.)
-The output of the model is therefore either:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">I am process 1.
-I am process 2.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>or:</p>

-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">I am process 2.
-I am process 1.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>After the two processes have finished their activities, the <code>run</code> statement
-in the model finishes, and the simulation ends.</p>
-</div>
-<div class="paragraph">
-<p>
-An important property of statements is that they are executed <em>atomically</em>.
-It means that execution of the statement of one process cannot be interrupted
-by the execution of a statement of another process.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tut-a-process-in-a-process">A process in a process</h4>
-<div class="paragraph">
-<p>The view of a process being a wrapper around many other processes is supported
-by allowing to use the <code>run</code> statement inside a process as
-well. An example:</p>

-<div class="content">

-<h4 id="tut-many-processes">Many processes</h4>
-<div class="paragraph">
-<p>Some models consist of many identical processes at a single level. The

-In <a href="#tut-chapter-processes">Processes</a> processes have been introduced.
-This chapter describes channels, denoted by the type <code>chan</code>.
-A channel connects two processes and is used for the transfer of data or just
-signals.
-One process is the sending process, the other process is the receiving process.
-Communication between the processes takes place instantly when both processes
-are willing to communicate, this is called <em>synchronous</em> communication.</p>

-<div class="sect3">
-<h4 id="tut-a-channel">A channel</h4>
-<div class="paragraph">
-<p>The following example shows the sending of an integer value between two
-processes via a channel.

-<div class="paragraph">
-<p>In this case, the producer sends a finite stream of integer values (5 numbers)

-<p>The model instantiates processes <code>P</code> and <code>C</code>.

-</div>
-<div class="paragraph">
-<p>Process <code>P</code> can send a value of type <code>int</code> via the actual channel
-parameter <code>a</code> to process <code>C</code>.
-In this case <code>P</code> first tries to send the value <code>0</code>.
-Process <code>C</code> tries to receive a value of type <code>int</code> via the actual channel

-Both processes can communicate, so the communication occurs and the value
-<code>0</code> is sent to process <code>C</code>.
-The received value is assigned in process <code>C</code> to variable <code>x</code>.
-The value of <code>x</code> is printed and the cycle starts again.
-This model writes the sequence <code>0, 1, 2, 3, 4</code> to the screen.</p>

-<h4 id="tut-synchronization-channels">Synchronization channels</h4>
-<div class="paragraph">
-<p>Above, process <code>P</code> constructs the numbers and sends them to process <code>C</code>.
-However, since it is known that the number sequence starts at <code>0</code> and
-increments by one each time, there is no actual need to transfer a number.
-Process <code>C</code> could also construct the number by itself after getting a signal
-(a 'go ahead') from process <code>P</code>.
-Such signals are called synchronization signals, transfered by means of a
-synchronization channel. The signal does not carry any data,
-it just synchronizes a send and a receive between different processes.
-(Since there is no actual data transfered, the notion of sender and receiver
-is ambiguous. However, in modeling there is often a notion of 'initiator'
-process that can be conveniently expressed with sending.)</p>
-</div>
-<div class="paragraph">
-<p>The following example shows the use of synchronization signals between
-processes <code>P</code> and <code>C</code>.
-The connecting channel 'transfers' values of type <code>void</code>.
-The type <code>void</code> means that 'non-values' are sent and received;
-the type <code>void</code> is only allowed in combination with channels.
-The iconic model is given in the previous figure,

-<div class="paragraph">
-<p>In the previous chapter, a production system was discussed that passes values
-from one process to the next using channels, in a synchronous manner.
-(Sender and receiver perform the communication at exactly the same moment in
-time, and the communication is instantaneous.)
-In many systems however, processes do not use synchronous communication, they
-use <em>asynchronous</em> communication instead.
-Values (products, packets, messages, simple tokens, and so on) are sent,
-temporarily stored in a buffer, and then received.</p>
-</div>
-<div class="paragraph">
-<p>In fact, the decoupling of sending and receiving is very important, it allows
-compensating temporarily differences between the number of items that are sent
-and received.
-(Under the assumption that the receiver is fast enough to keep up with the
-sender in general, otherwise the buffer will grow forever or overflow.)</p>
-</div>
-<div class="paragraph">
-<p>For example, consider the exchange of items from a producer process <code>P</code> to a
-consumer process <code>C</code> as shown in <a href="#tut-figure-pc2">A producer and a consumer</a>.</p>

-<div class="title">Figure 7. A producer and a consumer</div>
-</div>
-<div class="paragraph">
-<p>In the unbuffered situation, both processes communicate at the same time.
-This means that when one process is (temporarily) faster than the other, it
-has to wait for the other process before communication can take place.
-With a buffer in-between, the producer can give its item to the buffer, and
-continue with its work.
-Likewise, the consumer can pick up a new item from the buffer at any later
-time (if the buffer has items).</p>
-</div>
-<div class="paragraph">
-<p>In Chi, buffers are not modeled as channels, they are modeled as additional
-processes instead. The result is shown in <a href="#tut-figure-pbc">A producer and a consumer, with an additional buffer process</a>.</p>

-<div class="paragraph">
-<p>The producer sends its items synchronously (using channel <code>a</code>) to the buffer
-process. The buffer process keeps the item until it is needed.
-The consumer gets an item synchronously (using channel <code>b</code>) from the buffer
-when it needs a new item (and one is available).</p>
-</div>
-<div class="paragraph">
-<p>In manufacturing networks, buffers, in combination with servers, play a
-prominent role, for buffering items in the network.
-Various buffer types exist in these networks: buffers can have a finite or
-infinite capacity, they have a input/output discipline, for example a
-first-out queuing discipline or a priority-based discipline.
-Buffers can store different kinds of items, for example, product-items,
-information-items, or a combination of both.
-Buffers may also have sorting facilities, etc.</p>
-</div>
-<div class="paragraph">
-<p>In this chapter some buffer types are described, and with the presented
-concepts numerous types of buffer can be designed by the engineer.
-First a simple buffer process with one buffer position is presented, followed
-by more advanced buffer models.
-The producer and consumer processes are not discussed in this chapter.</p>

-<p>A conveyor is a long belt on which items are placed at the starting point of
-the conveyor.
-The items leave the conveyor at the end point, after traveling a certain
-period of time on the conveyor.
-The number of items traveling on the conveyor varies, while each item stays
-the same amount of time on the conveyor. It works like a buffer that provides

-
-
-To model a conveyor, you have to wait until a particular point in time. The
-Chi language has timers to signal such a time-out.
-The timer is started by assigning it a value. From that moment, it
-automatically decrements when time progresses in the model, until it reaches
-zero. The function <code>ready</code> gives the boolean value <code>true</code> if the timer is ready.
-The amount of time left can be obtained by reading from the variable.
-An example:</p>

- write("%f %f %b\n, time, real(t), ready(t));
- delay 1.0
- end
-end
-
-model M():
- run P()
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Initially, <code>time</code> equals <code>0.0</code>.
-The first action of process <code>P</code> is to delay the time for <code>10.0</code> time units.
-Now the value of <code>time</code> equals <code>10.0</code>. Nothing happens to timer <code>t</code> as
-it was already zero.
-At time <code>10</code> timer <code>t</code> is started with the value <code>5.0</code>.
-The output of the program is:</p>

-<p>Three items are placed on the conveyor. For simplicity, assume the conveyor is
-<code>60.0</code> meter long and has a speed of <code>1</code> meter per second.
-An item thus stays on the conveyor for <code>60.0</code> seconds.</p>
-</div>
-<div class="paragraph">
-<p>Item <code>0</code> has been placed on the conveyor <code>50.0</code> seconds ago, and will leave
-the conveyor <code>10.0</code> second from now. In the same way, item <code>1</code> will leave
-<code>30.0</code> seconds from now, and <code>2</code> leaves after <code>45.0</code> seconds. Each item
-has a <em>yellow sticker</em> with the time that the item leaves the conveyor. Based
-on this idea, tuple type <code>conv_item</code> has been defined, consisting of a
-field <code>item</code>, denoting the received item, and a timer field <code>t</code>, with the
-remaining time until the item leaves the conveyor:</p>

-to the next process. The conveyor sends items to a process that is always
-willing to a receive an item, this implies that the conveyor is never blocked.
-Blocking implies that the items nevertheless are transported to the end of the

-</div>
-</div>
-<div class="paragraph">
-<p>This simulation sends a single product through the line, prints the flow time,
-and exits. (All processes end, which makes that the <code>run</code> statement and the
-model end as well.)</p>
-</div>
-<div class="paragraph">
-<p>In this case, the answer is even obvious without running the simulation.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tut-exit">Simulating infinite systems</h4>
-<div class="paragraph">
-<p>For other systems, it is much harder to decide when enough has been simulated.
-Typically, a process (<code>E</code> in the example below), collects values of the
-property of interest (for example flow time of products), until it has
-collected enough samples to draw a conclusion, and compute the resulting value.</p>
-</div>
-<div class="paragraph">
-<p>After doing so, the problem arises to let all processes know the simulation
-should be stopped. This can be programmed in the model (such as adding
-channels to
-signal termination of the simulation to all processes). A simpler alternative
-is to use the <code>exit</code> statement, in the following way:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">proc real E(chan? real a, int N):

- exit total / N
-end
-
-model real M(... int N):
- ...
-
- run ..., E(..., N);
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>In process <code>E</code>, the average flow time is calculated and given as
-argument of the <code>exit</code> statement. At the moment this statement is executed,
-the model and all processes are killed, and the computed value becomes the
-exit value (the result) of the simulation. The <code>real</code> type before
-the name <code>E</code> denotes that the process may perform an <code>exit</code> statement
-returning a real value. The model runs the <code>E</code> process, so it may also give
-an exit value as result. These types are called <em>exit type</em>.
-Exit values are printed to the screen by the simulator when it ends the
-model simulation.</p>
-</div>
-<div class="paragraph">
-<p>Another option is to use <code>write</code> to output the computed value, and use
-<code>exit</code> without argument. In that case, the exit value is of type <code>void</code>.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tut-experiment">Simulating several scenarios</h4>
-<div class="paragraph">
-<p>The above works nicely for single model simulations. The model is started one
-time, and it derives a result for a single scenario.</p>
-</div>
-<div class="paragraph">
-<p>Often however, you want to perform several model simulations. This can be the
-exact same scenario when the model has stochastic behavior, or it can be
-with different parameter values each time (to investigate system behavior
-under different circumstances).
-In such cases, you can use an experiment, like below:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">xper X():

- write("%2d: %.2f\n", n, v)
- end
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The experiment <code>X</code> looks just like a function, except that it has no
-<code>return</code>
-statement. It can however 'call' a model like a function. In the example above
-<code>M(n)</code> starts a simulation with model <code>M</code> and the given value for <code>n</code>.
-When the model exits by means of the <code>exit</code> statement (this is required!),
-the computed exit
-value of the (model) simulation is assigned to variable <code>v</code>. In the
-experiment, this value can be used for post-processing, or in this case, get
-printed as result value in a table.</p>

-<div class="paragraph">
-<p>
-The <a href="http://www.w3.org/TR/SVG11/">Scalable Vector Graphics</a> (SVG) file
-format is a widely used, royalty-free standard for two-dimensional vector
-graphics, developed by the <a href="http://www.w3.org/">World Wide Web Consortium</a>
-(W3C). SVG images consist of three types of objects: vector graphic shapes
-(rectangles, circles, etc.), raster images, and text. The benefit of vector
-images formats over raster image formats, is that raster images are created
-with a fixed size, while vector images contain a description of the image and
-can be rendered at any size without loss of quality.</p>
-</div>
-<div class="paragraph">
-<p>
-
-SVG image files are stored in an
-<a href="http://en.wikipedia.org/wiki/XML">XML</a>-based file format. This means that
-they can be edited with any text editor. However, it is often more convenient
-to edit them with a drawing program that supports vector graphics, such as
-<a href="http://www.adobe.com/products/illustrator.html">Adobe Illustrator</a>
-or <a href="https://inkscape.org/">Inkscape</a>.
-Most modern web browsers also support display of SVG images.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tut-visualization">Visualization</h4>
-<div class="paragraph">
-<p>An SVG file has a tree structure; (graphical) elements are drawn in the same
-order as they appear in the file. Elements further down in the file are thus
-drawn on top of earlier elements. Also, each element has a position and size.
-They may have other properties like a color or a gradient as well. There are
-also 'administrative' elements, that can group, scale, or rotate parts of the
-tree. The website of Jakob Jenkov has a very nice
-<a href="http://tutorials.jenkov.com/svg">SVG Tutorial</a>.</p>
-</div>
-<div class="paragraph">
-<p>The SVG visualization by the Chi simulator exploits this structure. You access
-the elements, and literally change the value of their properties or copy part
-of the tree. The
-<a href="http://xmlgraphics.apache.org/batik/">Apache Batik SVG Toolkit</a>
-used for drawing the SVG image at the
-screen notices the changes, and updates the displayed image.</p>

-(<code>while event > time:</code>), it cycles through getting a product, processing
-it for <code>uptime</code> time units, and sending the product out again. After a
-few cycles, it has reached the <code>event</code> time, goes down, and waits for repair
-(<code>delay sample down;</code>). Once the machine is repaired it starts again.

-<p>A server is to be visualized with a circle that changes color depending on
-what the server is doing. Yellow means it is waiting for a product, green
-means processing, magenta means it is waiting to pass the finished product

-<p>As with the buffer process, the SVG visualization first opens a file
-connection to the visualizer and the SVG file with the
-<code>file f = open("SVG:gbse.svg", "w");</code> line. The filename of the <code>.svg</code> file
-must be the same as with the buffer process (the visualizer can only show
-one SVG file at a time).</p>
-</div>
-<div class="paragraph">
-<p>To display server state in the SVG visualization, we need a circle (called <em>arc</em> in
-SVG) named <code>s_0</code> and <code>s_1</code> (for server 0 and server 1), positioned behind
-its buffer. If there are not too many servers, and their number is fixed, one
-could simply add those arcs to the SVG file and be done with it.
-However, if you have a lot of servers, or you don’t know in advance how many
-you will have, you cannot add them beforehand, you need to construct the SVG
-elements 'on the fly'.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tut-copying-svg-elements">Copying SVG elements</h4>
-<div class="paragraph">
-<p>For showing the server states, arcs named <code>s_0</code> and <code>s_1</code> are required in
-SVG, which are created by copying and moving an SVG element. In this case, a
-server is represented by just one SVG element, so you can copy and move that
-one element. In general however, you want to copy several elements at the same
-time (for example you might want to copy graphical elements to display a work
-station, a server with its buffer).</p>
-</div>
-<div class="paragraph">
-<p>SVG has group elements, where you can put any number of (graphical) elements inside.
-When you copy a group, you copy its entire contents. The <code>gbse.svg</code> file as
-a group called <code>server</code>, containing an arc element called <code>s</code>. The server
-group is copied and moved, which causes the arc element to be copied and moved
-as well.</p>
-</div>
-<div class="paragraph">
-<p>Inside an SVG file, each element must have a unique <code>id</code>, that is, each
-element must have a unique name. When making a copy, the copied elements must
-thus also be given a new name. The entire operation is performed with sending
-a <code>copy [node], [prefix], [suffix]</code> command to the SVG visualizer. It
-takes the element named <code>[node]</code>, and makes a full copy of it
-(all elements inside it are also copied). For each copied element the
-<code>[prefix]</code> is added in front of its <code>id</code> name, and the <code>[suffix]</code> is
-added behind it.</p>
-</div>
-<div class="paragraph">
-<p>The <code>writeln(f, "copy server, , _x%d", num);</code> line in the Chi simulation
-performs the copy operation for the servers. It takes the <code>server</code> group
-element (which contains an <code>s</code> arc element), and adds nothing in front of
-the names (there is no text between the first and the second comma). It
-appends the names with <code>_x0</code> for the first server, and <code>_x1</code> for the
-second server. The result is thus a copy of the <code>server</code> group, called
-<code>server_x0</code> or <code>server_x1</code>, containing an arc <code>s_x0</code> respectively
-<code>s_x1</code>.</p>
-</div>
-<div class="paragraph">
-<p>Note that the copy command performs copying, and nothing else. Since the
-copied element is exactly at the same position as the original, you don’t see
-copies. This is however fixed by a move command explained next.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tut-moving-svg-elements">Moving SVG elements</h4>
-<div class="paragraph">
-<p>You often want to position an SVG element at some point in the display. The
-simplest way to do that is to change its <code>x</code> and <code>y</code> attributes, much
-like the <code>height</code> attribute of the buffer rectangle was modified. Another
-solution is to perform a relative move, using transform/translate.</p>
-</div>
-<div class="paragraph">
-<p>This works, until you add a transformation element that changes the coordinate
-system. Sometimes you do this consciously, for example adding a 'flip'
-transformation to fix the vertical coordinates. At other times the SVG editor
-may insert one, for example when you rotate or scale some part of the drawing.</p>
-</div>
-<div class="paragraph">
-<p>The Chi SVG visualizer has a <code>absmove [node] ([xpos], [ypos])</code>
-command to handle this case. It computes a transformation to get the top-left
-corner of the element named <code>[node]</code> at position (<code>[xpos]</code>, <code>[ypos]</code>).
-Keep in mind that the vertical coordinate starts at the top, and goes down.</p>
-</div>
-<div class="paragraph">
-<p>There are limitations to this command, in some case it may fail (see the
-<a href="#ref-chapter-svg-visualization">reference manual</a> for details about the
-command). It is recommended to use this command one time on an element to move
-it to a known base position. Once it is at a known position, change the <code>x</code>
-and <code>y</code> coordinates of a child element (to avoid disturbing the base
-position), to move relative to that base position. Another solution is to
-perform a relative move, using transform/translate.</p>
-</div>
-<div class="paragraph">
-<p>In the Chi simulation, the
-<code>writeln(f, "absmove s_x%d (%d, 325)", num, num*420+150);</code> line moves the
-copied <code>s_x0</code> and <code>s_x1</code> arcs to the right
-position in the display.</p>

-<div class="paragraph">
-<p>Creating and running a process is done with <a href="#ref-sub-process-statements">Sub-process statements</a>
-(<code>start</code> or <code>run</code>) from another process or from a model.</p>

-</div>
-<div class="paragraph">
-<p>Another common pattern is that the same computation is needed at several

-</div>
-<div class="paragraph">
-<p>However, since a function represents a computation (that is, calculation of an

-<ul>
-<li>
-<p>A computation is performed instantly, no time passes. This means that you

-<li>
-<p>A computation outputs a result. You cannot have a function that has no

-</li>
-<li>
-<p>A computation is repeatable. That means if you run the

-<em>every time</em>. Also in the environment of the function, there should be no
-changes. This idea is known as <em>mathematical functions</em>.</p>
-<div class="paragraph">
-<p>A consequence of having mathematical functions is that you cannot interact
-with 'outside'. No querying of the current time, no communication, no select
-statement, and no use of distributions.</p>

-</div>
-<div class="paragraph">
-<p>The definition is very similar to other definitions. It starts with an

-<p>The primary goal of an <code>xper</code> is to allow you to run one or more model

-<p>The model above is very short to keep the example compact. In practice it will

-The experiment <code>X</code> makes ten calls to the model. Each call causes the

-call, adding it to <code>total</code>.
-After the ten model simulations, the experiment outputs the average value of
-all model simulations.</p>

-<p>An <code>Addressable</code> is a variable. If the variable has a tuple type (see

-Similarly, if the variable is a list (see <a href="#ref-list-type">List type</a>) or a
-dictionary (see <a href="#ref-dictionary-type">Dictionary type</a>) assignment is done to one
-element by using Path 2. The <code>Expression</code> here is evaluated before <em>any</em>

-Since selected elements may also have a type that allows selection, element
-selection can be repeated.</p>
-</div>
-<div class="paragraph">
-<p>After processing the element selections at the left, it is known where
-values are assigned to. If there is exactly one addressable at the left, its
-type must match with the type of the value at the right (which may be a
-constructed tuple value as explained above). The value gets copied into the
-variable (or in its element if one is selected).
-If there are several addressable values at the left, the number of values must
-be equal to the length of the tuple from the expression(s) at the right, and
-each field of the right tuple must pair-wise match with the type of the
-addressed element at the left. In the latter case, all assignments are done at
-the same moment.</p>
-</div>
-<div class="paragraph">
-<p>For a few examples, a number of variable declarations are needed:</p>

-<div class="listingblock">
-<div class="content">

-<div class="paragraph">
-<p>The variable declarations introduce integer variables <code>x</code> and <code>y</code>, a real

-fields, and a function variable <code>f</code>.</p>
-</div>
-<div class="paragraph">
-<p>For reasons of clarity, initialization of the variables has been omitted.
-Also, expressions at the right are simple values. However, you may use all
-allowed expression operations explained in the next chapter
-(<a href="#ref-chapter-expressions">Expressions</a>) to obtain a value to assign.
-The first assignments show assignment of values to variables where there is
-one explicit value for every assigned variable:</p>

-<p>The first assignment statement assigns 3 to <code>x</code>. The second assignment
-assigns the return value of the function call <code>f(y)</code> to tuple <code>t</code>. The
-third assignment assigns 4 to <code>x</code> and 5 to <code>y</code> at the same time. The
-fourth assignment assigns the value of <code>x+x</code> to the first element of the

-is called <em>packing</em>, it 'packs' the sequence of values into one tuple. The
-opposite operation is demonstrated in the second assignment. The value of each
-field of <code>t</code> is assigned to a separate variable. The types of the variables
-at the left have to pair-wise match with the field types of the tuple at the
-right. This assignment is called <em>unpacking</em>, it 'unpacks' a tuple value into
-its separate elements.
-The third assignment does the same as the second assignment, the difference is
-that the value at the right is obtained from a function call. The origin of
-the value is however irrelevant to the assignment statement.</p>

-<p>The Chi language has two statements for repeatedly executing a body (a

-<div class="paragraph">
-<p>A while loop starts with the keyword <code>while</code> with a boolean condition.
-Between the colon and the <code>end</code> keyword, the body of statements is given,
-which is executed repeatedly.</p>
-</div>
-<div class="paragraph">
-<p>Executing an iterative <code>while</code> statement starts with evaluating the boolean
-condition. If it does not hold, the <code>while</code> statement ends (and execution
-continues with the statement following the while statement). If the condition
-holds, the statements in the body are executed from start to end (unless a
-<code>break</code> or <code>continue</code> statement is executed, as explained below).
-After the last statement has been executed, the <code>while</code> statement starts
-again from the beginning, by evaluating the boolean condition again.</p>
-</div>
-<div class="paragraph">
-<p>As an example, consider the following code:</p>

-<div class="paragraph">
-<p>At first, the <code>i < 10</code> condition holds, and the body of the <code>while</code>
-statement (two assignment statements) is executed.
-After the body has finished, <code>i</code> has been incremented, but is still less
-than <code>10</code>. The condition again holds, and the body is again executed, etc.
-This process continues, until the final statement of the body increments <code>i</code>
-to <code>10</code>. The condition does not hold, and execution of the <code>while</code>

-<p>A common case for iterating is to execute some statements for every value in a

-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">list int xs;

-</div>
-</div>
-<div class="paragraph">
-<p>where the <code>...</code> line represents the statements that should be executed for
-each value <code>x</code> of the list. This is a very common case. Chi has a special
-statement for it, the <code>for</code> statement. It looks like:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">list int xs;
-
-for x in xs:
- ...
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This code performs the same operation, the statements represented with <code>...</code>
-are executed for each value <code>x</code> from list <code>xs</code>, but it is shorter and
-easier to write.
-The advantages are mainly a reduction in the amount of code that must be
-written.</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>No need to create and update the temporary index variable <code>i</code>.</p>
-</li>
-<li>
-<p>Variable <code>x</code> is declared implicitly, no need to write a full variable
-declaration for it.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>The behavior is slightly different in some circumstances.</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>There is no index variable <code>i</code> that can be accessed afterwards.</p>
-</li>
-<li>
-<p>When the <code>...</code> statements modify the source variable (<code>xs</code> in the
-example), the <code>while</code> statement above uses the changed value. The <code>for</code>
-statement continues to use the original value of the source variable.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>Continuing use of the original source value can be an advantage or a
-disadvantage, depending on the case. Using the new value gives more
-flexibility, keeping the old value makes the <code>for</code> statement more
-predictable, for example indices in the source variable stay valid.</p>
-</div>
-<div class="paragraph">
-<p>Besides iterating over a list with <code>for</code>, you can also iterate over element
-values of a set, or over key-value tuples of a dictionary, for example:</p>

-<div class="listingblock">
-<div class="content">

-</div>
-</div>
-<div class="paragraph">
-<p>When iterating over a set or a dictionary, the order of the elements is

-<p>The <code>break</code> statement may only be used inside the body of a loop statement.

-Channel directions of the formal parameters must be a sub-set of the channel

-<div class="paragraph">
-<p>The optional assignment of the process to a process variable (which must be of

-keyword at the end to terminate the unwind.</p>

-the channel.)
-When an alternative is chosen by the select statement, the send or receive
-statement are performed (if it was present). If additional statements were
-given in the alternative using Path 3, they are executed after the
-communication has occurred (if a send or receive was present).</p>

-<div class="paragraph">
-<p>The select either receives a value through channel <code>a</code>, or it sends the

-time to select the second alternative).</p>
-</div>
-<div class="paragraph">
-<p>After communication has been performed, the first alternative appends the

-<p>Here <code>cs</code> is a list of channels, for example <code>list(5) chan int cs</code>. (See

-the <code>enumerate(cs)</code> (see <a href="#ref-list-expression">List expressions</a> for details about
-<code>enumerate</code>), assigning the index and the channel to local <code>i</code> and <code>c</code>
-variables. The <code>SelectAlternative</code> uses the variables to express the actions
-to perform (wait for a receive, and output some text saying that a value has
-been received).</p>
-</div>
-<div class="paragraph">
-<p>The above is equivalent to (if list <code>cs</code> has length 5):</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">select

-<p>The <strong>element access</strong> and <strong>slicing</strong> operators use numeric indices to denote a

-the string, for example index value <code>-1</code> points to the last character of a
-string.
-Unlike lists, both the <strong>element access</strong> and the <strong>slicing</strong> operators return a
-string. The former constructs a string with only the indicated character,
-while the latter constructs a sub-string where the first character is at index
-<strong>low</strong>, the second character at index <strong>low</strong> + <strong>step</strong>, and so on, until
-index value <strong>high</strong> is reached or crossed. That final character is not included
-in the result (that it, the <strong>high</strong> boundary is excluded from the result).
-If <strong>low</strong> is omitted, it is 0, if <strong>high</strong> is omitted, it is the length of the

-<p>The <strong>union</strong> of two sets means that the <strong>lhs</strong> elements and the <strong>rhs</strong> elements

-<p>The <strong>element access</strong> operator accesses the value of a key. Querying the value

-<img src="./reference-manual/rail_diagrams/literal_tuple.png" alt="literal tuple">

-</div>
-<div class="paragraph">
-<p>A literal tuple is a comma separated sequence of expressions of length two or
-longer, surrounded by a
-pair of parentheses. The number of expressions and the type of each expression
-decide the tuple type. For example:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">type tup = tuple(bool b; real r);
-
-tup t = (true, 3.48);</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The type named <code>tup</code> is a tuple type with a boolean field and a real field.
-The expression <code>(true, 3.48)</code> constructs the same tuple type, thus it can be
-assigned to variable <code>t</code>. Names of the fields are not relevant in this
-matching, for example variable declaration (and initialization)
-<code>tuple(bool z; real w) u = t</code> is allowed, since the types of
-the fields match in a pair-wise manner.</p>
-</div>
-<div class="paragraph">
-<p>A field of a tuple can be accessed both for read and for assignment by the name
-of the field:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">bool c;
-
-c = t.b; # Read the 'b' field.
-t.b = false; # Assign a new value to the 'b' field.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>In the latter case, only the assigned field changes, all other fields keep the
-same value.</p>
-</div>
-<div class="paragraph">
-<p>Tuples can also be packed and unpacked. Packing is assignment to all fields,
-while unpacking is reading of all fields into separate variables:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">real q;
-
-t = false, 3.8; # Packing of values into a tuple.
-
-c, q = t; # Unpacking into separate variables.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Packing is very closely related to literal tuples above. The difference is
-that packing can be done only like above in an assignment to a tuple value,
-while a literal tuple works everywhere.</p>
-</div>
-<div class="paragraph">
-<p>Unpacking is very useful when the right side (<code>t</code> in the example) is more
-complex, for example, the return value of a function call, as
-in <code>c, q = f();</code>. In such cases you don’t need to construct an intermediate
-tuple variable.</p>
-</div>
-<div class="paragraph">
-<p>Packing and unpacking is also used in multi-assignment statements:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">a, b = 3, 4; # Assign 3 to 'a', and 4 to 'b'.
-
-a, b = b, a; # Swap values of 'a' and 'b'.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The latter works due to the intermediate tuple that is created as part in the

-to a <code>run</code> or <code>start</code> statement. (See <a href="#ref-run-and-start-statements">Run and start statements</a> for
-details on how to create a new process.)

-</div>
-<div class="paragraph">
-<p>Each comma-separated list of real number values is a row of the matrix. The

-<p><code>m</code> is a matrix with two rows and three columns. A comma separates two
-columns from each other, a semi colon separates two rows.</p>
-</div>
-<div class="paragraph">
-<p>The syntax demands at least one semi colon in a literal matrix value, which
-means you cannot write a matrix literal with a single row directly. Instead,
-write a cast expression that converts a list of real numbers to a matrix with

-<ul>
-<li>
-<p>The <code>ElementaryType</code> block contains types that do not build on other types.
-They are explained further in <a href="#ref-elementary-type">Elementary types</a>.</p>
-</li>
-<li>
-<p>The <code>ContainerType</code> block contains types that can store values of a single
-other type, the 'list', 'set', and 'dictionary' type. These types are further
-explained in <a href="#ref-container-type">Container types</a>.</p>
-</li>
-<li>
-<p>The <code>TupleType</code> block describes 'tuples', a type that can hold values of
-several other types.</p>
-</li>
-<li>
-<p>The <code>ChannelType</code> blocks describes communication channels that connect
-processes with each other, see <a href="#ref-channel-type">Channel type</a> for more explanation.</p>
-</li>
-<li>
-<p>The <code>DistributionType</code> block contains the stochastic distribution type,
-explained in <a href="#ref-distribution-type">Distribution type</a>.</p>
-</li>
-<li>
-<p>The <code>FunctionType</code> can hold a function definition. It allows you to pass
-a function to a process or another function. It is further explained in
-<a href="#ref-function-type">Function type</a>.</p>
-</li>
-<li>
-<p>The <code>ProcessType</code> can hold a process definition. It allows you to pass

-<p>The <code>TypeName</code> is the name of a type defined with a <code>type</code> definition

-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">type lot = real;

-<p>The <code>lot x</code> variable declaration (explained in <a href="#ref-variable-declarations">Local variables</a>)

-variable <code>x</code>.</p>
-</div>
-<div class="paragraph">
-<p>The <code>EnumTypeName</code> is similar, except it uses an enumeration definition (see

-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="chi">enum FlagColours = {red, white, blue};
-

- FlagColours x = white;
-
- ...
-end</code></pre>
-</div>

-suffix that is added to the <code>id</code> of all copied elements. Since the <code>id</code>
-of all elements must be unique, leaving both the prefix and the suffix empty
-gives an error about duplicate <code>id</code> labels.</p>
-</div>
-<div class="paragraph">
-<p>Note that the element (and its descendants) is only copied, but not moved.
-In other words, after copying it is fully obscured by the original element.
-The next step is normally an absolute move command or an attribute command

-</li>
-<li>
-<p><strong>Move an element to an absolute position</strong></p>
-<div class="paragraph">

-<code>[ypos]</code> the vertical position to move to. This operation adds a
-translation to the <code>transform</code> attribute of the node such that the
-top-left corner of the bounding rectangle is moved to the provided position.
-It also takes the existing transformation into account, and in doing so,

-<div class="paragraph">
-<p>This manual explains how to use the Chi simulation software. Before using
-the software however, you need to install it. The software is part of the
-Eclipse ESCET software.</p>
-</div>
-<div class="paragraph">
-<p>Once you’re finished installing, you can start to
-<a href="#tool-chapter-software-operation">simulate</a> Chi programs. The easiest way to
-start simulation is to press the <em>F9</em> key in a Chi text editor, or when a Chi
-(a file with a <code>.chi</code> extension) is selected in the
-<em>Project Explorer</em> or <em>Package Explorer</em> tab.</p>

-<p>The Chi simulator software performs two steps internally:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Type checking of the Chi source file, and building a simulator for it.</p>
-</li>
-<li>
-<p>Running the created simulator.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>Starting with a <code>.chi</code> source file, both steps have to be performed for a
-simulation. As this is the common situation, the software normally combines
-both steps.
-If you run many experiments with the same file, it becomes useful to skip the
-first step. How to do this is explained in <a href="#tool-compile-or-simulate">Compile only</a>.
-In addition, the software can be run from the command line. In that case,
-command-line options as explained in <a href="#tool-chapter-command-line">Command line options</a> need to be
-specified.</p>
-</div>
-<div class="sect3">
-<h4 id="tool-compile-and-simulate">Compile and simulate</h4>
-<div class="paragraph">
-<p>Normally, you want to simulate a <code>.chi</code> source file. The Chi simulator
-software uses two steps internally (first checking the input and building the
-simulator, then running the just created simulator), but these steps are
-combined in the dialog.</p>
-</div>
-<div class="paragraph">
-<p>The process starts by selecting the source file you want to use (a file with
-a <code>.chi</code> extension) in the <em>Project Explorer</em> or <em>Package Explorer</em> tab, and opening the
-popup menu with the right mouse button from that selection.
-Alternatively, open the file in the editor, and use the right mouse button to
-get a similar popup menu.</p>
-</div>
-<div class="paragraph">
-<p>From the popup menu, select <em>Simulate Chi file</em> entry. The
-selection causes the <em>Console</em> view to be opened in Eclipse, and a
-dialog window pops up to set the simulator options like below.</p>
-</div>
-<div class="imageblock">
-<div class="content">
-<img src="./tool-manual/chi_simulator_dialog.png" alt="chi simulator dialog">
-</div>
-</div>
-<div class="paragraph">
-<p>The dialog shows the source file being used in the <em>Input file path</em> box.
-Below it, in the <em>Instance</em> box, you can enter how to run the
-model or the experiment of the source file. The syntax of the input is the same
-as you would
-write it in your Chi file. For example, with a model definition
-<code>model M(list real xs, int n): ... end</code>, you could write <code>M([1.5, 2.81], 15)</code> as
-model instantiation. If you leave the entry empty, the simulator tries to find
-an experiment without any parameters (for example <code>X()</code>). If that fails, it
-tries to find a model without any parameters (typically <code>M()</code>). If both
-attempts fail, or the simulator finds more than one such experiment or model,
-an error is reported.</p>
-</div>
-<div class="paragraph">
-<p>If you want to set an initial seed (see
-<a href="#tut-simulating-stochastic-behavior">Simulating stochastic behavior</a> for a discussion), you can use the
-<em>Initial seed value</em> box. Value <code>0</code> means 'create a new one'.</p>
-</div>
-<div class="paragraph">
-<p>This is all you have to do, select <em>OK</em> at the bottom. The software
-performs its two steps, and if no errors are found, it runs the model.</p>
-</div>
-<div class="sect4">
-<h5 id="tool-quick-simulate">Quick simulate</h5>
-<div class="paragraph">
-<p>For files that do not need any further configuration before
-they are run, there is a <em>Quick simulate Chi file</em>. This menu
-option assumes the default configuration (a parameter-less experiment or
-model needs to be run with a new seed), skips the dialog (saving you from
-having to press <em>OK</em>) and immediately proceeds with processing the Chi file.</p>
-</div>
-<div class="paragraph">
-<p>This functionality is also available from the Chi text editor, by pressing
-the <em>F9</em> key. Alternatively, you can select a Chi file in the
-<em>Project Explorer</em> or <em>Package Explorer</em>, and press the
-<em>F9</em> key.</p>
-</div>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tool-compile-or-simulate">Compile only</h4>
-<div class="paragraph">
-<p>The above is convenient for simple experiments, but checking the input and
-building a simulator each time is tedious if you want to do several
-experiments with the same source file.
-For this reason, each step can be done separately as well.</p>
-</div>
-<div class="paragraph">
-<p>Only building a simulator starts in the same way as above, select a <code>.chi</code>
-source file from the <em>Project Explorer</em>, the <em>Package Explorer</em>
-or an editor window, and right-click at it. Select the <em>Simulate Chi file</em>
-option from the popup menu. As the file only gets compiled, the
-simulator options are of no interest. Instead switch to the <em>Compiler</em>
-tab. It looks like this:</p>
-</div>
-<div class="imageblock">
-<div class="content">
-<img src="./tool-manual/chi_compiler_dialog.png" alt="chi compiler dialog">
-</div>
-</div>
-<div class="paragraph">
-<p>Most settings are only useful for developers, but at the bottom, check the
-<em>Write the compiled Java code to a .cchi file</em> box, and click
-<em>OK</em> at the bottom. Setting this option causes the simulator
-software to check the input file, build a simulator, write the constructed
-simulator to a <code>.cchi</code> file (a compiled Chi file), and quit. No simulation
-of the Chi model is performed at this time.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tool-simulate-a-compiled-model">Simulate a compiled model</h4>
-<div class="paragraph">
-<p>You can simulate the Chi model from the <code>.cchi</code> file now, by selecting
-that file as source file by right-clicking on it. Select the
-<em>Simulate Chi file</em> or the <em>Quick simulate Chi file</em>
-option as before, and proceed with setting the
-simulator options and running the model as-if you selected a normal <code>.chi</code>
-file, as explained in <a href="#tool-compile-and-simulate">Compile and simulate</a> above.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="tool-terminating-a-simulation">Terminating a simulation</h4>
-<div class="paragraph">
-<p>A simulation ends when:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>The model goes into a deadlock state,</p>
-</li>
-<li>
-<p>An <code>exit</code> statement is performed (see <a href="#tut-exit">experiments</a>
-in the tutorial),</p>
-</li>
-<li>
-<p>The simulation is terminated by the user, via the console
-<em>Terminate</em> button (explained below), or</p>
-</li>
-<li>
-<p>A runtime error occurs.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>The simulation can be stopped at any time by using the <em>Terminate</em> button
-(image::./tool-manual/terminate_button.png[]),
-located at the upper right corner of the console.
-Note however that if the console does not have the focus, this button may not
-be visible. If the button is not visible, click somewhere in the console to
-make the button appear. If even then the button is still not available, it may
-still appear if you <em>Maximize</em> the console. Also note that the
-button has no effect while the simulator interactively asks for input from the
-console. However, once the console input is provided, and <em>ENTER</em> is
-pressed, the termination request will be processed.</p>

-<div class="paragraph">
-<p>When you run the Chi software from the command line, the interactive dialog

-default), and everything has to be specified at the command line instead.</p>

-<p>The CIF language is a powerful declarative automata-based modeling language
-for the specification of discrete event, timed (linear dynamics), hybrid
-(piecewise continuous dynamics) systems. It can be seen as a rich state
-machine language with the following main features:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Modular specification with synchronized events and communication between
-automata.</p>
-</li>
-<li>
-<p>Many data types are available (booleans, integers, reals, tuples, lists,
-arrays, sets, and dictionaries), combined with a powerful expression language
-for compact variables updates.</p>
-</li>
-<li>
-<p>Text-based specification of the automata, with many features to simplify
-modeling large non-trivial industrial systems.</p>
-</li>
-<li>
-<p>Primitives for supervisory controller synthesis are integrated in the
-language.</p>

-<div class="ulist">
-<ul>
-<li>
-<p>Text-based editor that allows to easily specify and edit models.</p>
-</li>
-<li>
-<p>Feature-rich powerful data-based synthesis tool. A transformation to the
-supervisory controller synthesis tool Supremica is also available.</p>
-</li>
-<li>
-<p>A simulator that supports both interactive and automated validation of
-specifications. Powerful visualization features allow for interactive
-visualization-based validation.</p>
-</li>
-<li>
-<p>Conversion to formal verification tools such as mCRL2 and UPPAAL.</p>
-</li>
-<li>
-<p>Implementation language code generation (PLC languages, Java, C, and

-<h2 id="tut-chapter-index">Language tutorial</h2>
-<div class="sectionbody">
-<div class="paragraph">
-<p>This tutorial introduces the CIF language. It explains the general idea
-behind the concepts of the language, and shows how to use them, all by means of
-examples. The tutorial is focused on giving a short introduction to CIF, and
-does not cover all details. It is recommended reading for all CIF users.</p>
-</div>
-<div class="sect2">
-<h3 id="tut-introduction">Introduction</h3>
-<div class="paragraph">
-<p>CIF stands for <strong>C</strong>ompositional <strong>I</strong>nterchange <strong>F</strong>ormat for hybrid
-systems. CIF is primarily used to create models of physical systems and their
-controllers, describing their behavior. However, CIF is a general-purpose
-modeling language, and can be used to model practically anything, ranging from
-physical real-world systems to abstract mathematical entities.</p>
-</div>
-<div class="paragraph">
-<p>
-
-</p>
-</div>
-<div class="paragraph">
-<p>CIF supports discrete event models, that are mostly concerned with what
-happens, and in which order. CIF also supports timed systems, where timing
-plays and explicit role, and hybrid systems, which combine the discrete events
-with timing. This makes CIF suitable for modeling of all kinds of systems.</p>
-</div>
-<div class="paragraph">
-<p>The CIF tooling puts a particular focus on supporting the entire development
-process of controllers. However, just as the CIF language, the CIF tooling can
-be applied much more generally. The tooling allows among others specification,
-supervisory controller synthesis, simulation-based validation and
-visualization, verification, real-time testing, and code generation.</p>

-<div id="lang-tut-basics-automata-events" class="paragraph">
-<p>Automaton <code>lamp</code> declares two <em>events</em>, named <code>turn_on</code> and <code>turn_off</code>.
-Events model things that can happen in a system. They represent changes. For
-instance, the <code>turn_on</code> event indicates that the lamp is being turned on. It
-represents the change from the lamp being off to the lamp being on. The event
-declaration in the <code>lamp</code> automaton declares two events. The event
-declaration only indicates that these events exist, it does not yet indicate
-when they can happen, and what the result of them happening is.</p>

-</div>
-<div id="lang-tut-basics-automata-location" class="paragraph">
-<p>All automata have one or more <em>locations</em>, which represent the mutually
-exclusive <em>states</em> of the automaton. The <code>lamp</code> automaton has two
-<em>locations</em>, named <code>on</code> and <code>off</code>. Automata have an <em>active</em> or <em>current</em>
-location. That is, for every automaton one of its location is the active
-location, and the automaton is said to be <em>in</em> that location. For instance,
-the <code>lamp</code> automaton is either in its <code>on</code> location, or in its <code>off</code>
-location.</p>

-<div id="lang-tut-basics-automata-loc-init" class="paragraph">
-<p>Initially, the lamp is on, as indicated by the <code>initial</code> keyword in the

-</div>
-<div class="paragraph">
-<p>The <code>lamp</code> automaton has an edge with the <code>turn_off</code> event, in its <code>on</code>
-location, going to the <code>off</code> location. Whenever the lamp is on, the <code>lamp</code>
-automaton is in its <code>on</code> location. Whenever the lamp is turned off, the
-<code>turn_off</code> event happens. The edge with that event indicates what the
-result of that event is, for the <code>on</code> location. In this case the result is
-that the lamp will then be off, which is why the edge goes to the <code>off</code>
-location.</p>

-<div class="sect3">
-<h4 id="tut-basics-chapter-synchronizing-events">Synchronizing events</h4>
-<div class="paragraph">
-<p>
-The power of events is that they synchronize. To illustrate this, consider
-the following CIF specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton producer:
- event produce, provide;
-
- location producing:
- initial;
- edge produce goto idle;
-
- location idle:
- edge provide goto producing;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The automaton represents a producer that produces products, to be consumed
-by a consumer. The <code>producer</code> automaton starts in its <code>producing</code> location,
-in which it produces a product. Once the product has been produced, indicated
-by the <code>produce</code> event, the automaton will be in its <code>idle</code> location, where
-it waits until it can <code>provide</code> the produced product to the consumer. Once it
-has provided the product to the consumer, it will once again be <code>producing</code>
-another product. Consider also the following continuation of the above
-specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton consumer:
- event consume;
-
- location idle:
- initial;
- edge producer.provide goto consuming;
-
- location consuming:
- edge consume goto idle;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This second automaton represents a consumer that consumes products. The
-<code>consumer</code> is initially <code>idle</code>, waiting for a product from the producer.
-Once the producer has provided a product, the consumer will be <code>consuming</code>.
-Once it has consumed the product, as indicated by the occurrence of the
-<code>consume</code> event, it will become <code>idle</code> again.</p>
-</div>
-<div class="paragraph">
-<p>The specification has three events, the <code>produce</code> and <code>provide</code> events
-declared in the <code>producer</code> automaton, and the <code>consume</code> event declared in
-the <code>consumer</code> automaton. The <code>consumer</code> automaton, in its <code>idle</code>
-location, has an edge that refers to the <code>provide</code> event declared in the
-<code>producer</code> automaton. As such, that edge and the edge in the <code>idle</code>
-location of the <code>producer</code> automaton, refer to the same event.</p>
-</div>
-<div class="paragraph">
-<p></p>
-</div>
-<div class="sect4">
-<h5 id="tut-synchronization">Synchronization</h5>
-<div class="paragraph">
-<p>Events that are used in multiple automata, must <em>synchronize</em>. That is, if
-one of those automata performs a transition for that event, the other automata
-must also participate by performing a transition for that same event. If one
-of the automata that uses the event can not perform a transition in its current
-location, none of the automata can perform a transition for that event.</p>
-</div>
-<div class="paragraph">
-<p>Now, lets take a closer look at the behavior of the producer/consumer example.
-Initially, the <code>producer</code> automaton is in its <code>producing</code> location, and the
-<code>consumer</code> automaton is in its <code>idle</code> location. Since the <code>producer</code> is
-the only automaton that uses the <code>produce</code> event, and there is an (outgoing)
-edge in its current location for that <code>produce</code> event, the <code>producer</code> can
-go to its <code>idle</code> location by means of that event.</p>
-</div>
-<div class="paragraph">
-<p>Both the <code>producer</code> and <code>consumer</code> use the <code>provide</code> event. The
-<code>producer</code> has no edge with that event in its <code>producing</code> location, while
-the <code>consumer</code> does have an edge for that event in its <code>idle</code> location.
-Since events must synchronize, and the <code>producer</code> can not participate, the
-event can not occur at this time. This is what we expect, as the <code>producer</code>
-has not yet produced a product, and can thus not yet <code>provide</code> it to the
-consumer. The <code>consumer</code> will have to remain <code>idle</code> until the <code>producer</code>
-has produced a product and is ready to <code>provide</code> it to the <code>consumer</code>.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-The <code>producer</code> blocks the <code>provide</code> event in this case, and is said to
-<em>disable</em> the event. The event is not blocked by the <code>consumer</code>, and is thus
-said to be <em>enabled</em> in the <code>consumer</code> automaton. In the entire
-specification, the event is <em>disabled</em> as well, as it is disabled by at least
-one of the automata of the specification, and all automata must enable the
-event for it to become enabled in the specification.</p>
-</div>
-<div class="paragraph">
-<p>The only behavior that is possible, is for the <code>producer</code> to <code>produce</code> a

-<code>producer</code> is in its <code>producing</code> (p) location, and the <code>consumer</code> is in

-<div class="paragraph">
-<p>By using multiple automata, the producer and consumer were modeled
-independently, allowing for separation of concerns. This is an important
-concept, especially when modeling larger systems. In general, the large system
-is decomposed into parts, usually corresponding to physical entities. Each of
-the parts of the system can then be modeled in isolation, with little regard
-for the other parts.</p>
-</div>
-<div class="paragraph">
-<p>By using synchronizing events, the different automata that model different
-parts of a system, can interact. This allows for modeling of the connection
-between the different parts of the system, ensuring that together they

-Depending on the context in which it is used, non-determinism can mean

-<p>One cause of non-determinism is that multiple events are enabled, leading to

-Initially, the machines are <code>idle</code>. Then, they warm themselves up. Once they
-start processing, they set their boolean variable <code>claimed</code> to <code>true</code> to
-indicate that they claimed the shared resource. After processing, the machines
-release the resource, by setting <code>claimed</code> to <code>false</code>. They finish their
-processing cycle by cooling down, before starting the cycle for the next
-product. To ensure that a machine can not claim the resource if the other
-machine has already claimed it, the edges going to the <code>processing</code> locations
-have a guard that states that it is only allowed to claim the resource and
-start processing, if the other machine has not already claimed the resource.

-The lesson on <a href="#tut-data-chapter-discrete-variables">discrete variables</a> used
-the following CIF specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton counter:
- event increment, decrement;
-
- disc int count = 3;
-
- location:
- initial;
- edge decrement when count > 0 do count := count - 1;
- edge increment when count < 5 do count := count + 1;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The counter can repeatedly be incremented and decremented by one, as long as
-the count remains at least one and at most five. To keep the count in the
-allowed range of values, guards were used to limit the occurrence of the
-<code>increment</code> and <code>decrement</code> events.</p>
-</div>
-<div class="paragraph">
-<p>Instead of using guards, it is also possible to use state (exclusion)
-invariants, also called state invariants, or just invariants:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton counter:
- event increment, decrement;
-
- disc int count = 3;
-
- invariant count >= 0; // Added invariants
- invariant count <= 5;
-
- location:
- initial;
- edge decrement do count := count - 1; // No more guards
- edge increment do count := count + 1;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The guards on the edges have been replaced by the two invariants. The first
-invariant specifies that the value of variable <code>count</code> must always be at
-least zero. The second invariant specifies that the value must also be at most
-five.</p>
-</div>
-<div class="paragraph">
-<p>Invariants specify conditions that must always hold. Invariants must hold in
-the initial state, and all states reached via transitions. If a transition
-results in a state where an invariant doesn’t hold, the transition is not
-allowed and can’t be taken.</p>
-</div>
-<div class="paragraph">
-<p>For the counter example, initially the <code>count</code> is <code>3</code>. The edge for the
-<code>increment</code> event can be taken, leading to a state where the <code>count</code> is
-<code>4</code>. Taking another transition for the <code>increment</code> event leads to a state
-where the <code>count</code> is <code>5</code>. If we then were to take another transition for
-the <code>increment</code> event, the <code>count</code> would then become <code>6</code>. However, that
-violates the invariant. Therefore, in the state where the <code>count</code> is <code>5</code>,
-no transition for the <code>increment</code> event is possible. In other words, the
-invariant disables the transition for the <code>increment</code> event for that state.</p>
-</div>
-<div class="paragraph">
-<p>The two invariants can be specified in various ways:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">// Multiple invariants, each with a single predicate.
-invariant count >= 0;
-invariant count <= 5;

-// Single invariant, with multiple predicates.
-invariant count >= 0, count <= 5;
-
-// Single invariant, with single predicate.
-invariant count >= 0 and count <= 5;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Each of these variants leads to the exact same behavior, and which variant to
-use depends mostly on the modeler’s own preference.</p>
-</div>
-<div class="paragraph">
-<p>The benefit of guards over invariants is that they more explicitly state the
-condition under which an edge can lead to a transition. If a guard doesn’t
-hold, the edge can’t be part of a transition. It is thus immediately clear when
-the edge can lead to a transition. For invariants, the update has to be
-calculated first, after which the invariants can be evaluated for the state
-resulting from the transition. If one of the invariants doesn’t hold, the
-transition is not allowed. In the case of the invariants, it is not as
-immediately clear from the edge alone, when that specific edge can or can not
-lead to a transition.</p>
-</div>
-<div class="paragraph">
-<p>The benefit of invariants over guards is that they apply to all edges. If
-several edges in an automaton have updates to the same variable, then the
-invariants need to be specified only once, and apply to all transitions, for
-all edges. Using guards, all the edges that modify the variable would need
-their own guards, and if the updates are different, the different edges usually
-require different guards. Furthermore, if new edges with updates to the same
-variables are added, the invariant is already present, but guards have to be
-added, which can easily be forgotten. In those cases, invariants can thus help
-keep the specification consistent.</p>
-</div>
-<div class="paragraph">
-<p>Another benefit of invariants is that they explicitly state the conditions that
-must hold in relation to the variables, while guards specify the condition
-under which the update is allowed. Consider the following CIF specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">// Using invariants.
-automaton a:
- disc int x;
-
- invariant 0 <= x, x <= 100;
-
- location:
- initial;
- edge do x := 2 * x + 3;
-end
-
-// Using guards.
-automaton a:
- disc int x;
-
- location:
- initial;
- edge when x <= 48 do x := 2 * x + 3;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The goal is to keep the value of in the range [0..100]. The invariant is simple
-and direct. The guard however, has to state the condition under which the
-update does not violate the goal. That is, the upper bound has to be decreased
-by three, and the result has to be divided by two, to get the highest value
-(48) for which the update is still within the valid range of values. That is,
-for value 48 the update results in value 99 (2 * 48 + 3 = 99), and for value
-49 the update results in value 101 (2 * 48 + 3 = 99). The more complex the
-update, the harder it is to figure out the guard to use to keep satisfy the
-goal.</p>
-</div>
-<div class="paragraph">
-<p>You can of course also use <code>2 * x + 3 <= 100</code> as guard, instead of
-<code>x <= 48</code>. However, this duplicates part of the update in the guard.</p>
-</div>
-<div class="paragraph">
-<p>So far, all invariants have been specified in automata. They may however also
-be specified outside of the automata, similar to
-<a href="#tut-data-chapter-init-preds">initialization predicates</a>. It is generally
-recommended to place an invariant inside an automaton if the condition only
-applies to declarations from that automaton, and to place it outside of the
-automata if the condition applies to declarations of multiple automata.</p>
-</div>
-<div class="paragraph">

-Consider an elevator, consisting of three parts: a motor to make the elevator
-move up and down, a door that can be opened and closed to let passengers enter
-and exit, and an emergency button that can be used to stop the elevator in
-case of an emergency. The following CIF specification models the three parts:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton motor:
- event turn_on, turn_off;
-
- location off:
- initial;
- edge turn_on goto on;

-end
-
-automaton door:
- event open, close;
-
- location closed:
- initial;
- edge open goto opened;
-
- location opened:
- edge close goto closed;
-end
-
-automaton emergency_button:
- event push, release;
-
- location released:
- initial;
- edge push goto pushed;
-
- location pushed:
- edge release goto released;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Each part is modeled by an automaton. Since the automata don’t share any
-events, they operate independently. What is missing, is a controller that
-links the different automata, and controls them in a safe manner. Such a
-controller restricts the behavior of the individual automata, allowing only
-the combined behavior that is deemed desired. There are several ways to
-restrict events, including introducing synchronization between the different
-automata, and adding guards. The downside of these approaches it that they
-require modification of the automata. What if we wanted to specify the
-controller separately from the behavior of the physical system? We could
-introduce an additional automaton, that synchronizes with the existing
-automata. For instance, we could add the following to the CIF specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton controller:
- location:
- initial;
- edge motor.turn_on when door.closed and emergency_button.released;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This controller introduces restrictions for the <code>turn_on</code> event of the
-<code>motor</code>. In this particular case, the controller ensures that the motor may
-only be turned on when both the door is closed and the emergency button is
-released. By restricting the event, the controller prohibits the event from
-taking place in certain states, ensuring that only the desired behavior
-remains.</p>
-</div>
-<div class="paragraph">
-<p>It is nice that we can separate the description of the physical behavior of the
-elevator from the controller that controls it. This separation of concerns may
-make it easier to reason about the behavior, it may make it easier to adapt
-the controller when the physical system doesn’t change, and it may make it
-easier to reuse the model of the physical system for other purposes.</p>
-</div>
-<div class="paragraph">
-<p>However, modeling an automaton with a single location that must then also be
-<code>initial</code> requires quite some syntax. State/event exclusion invariants can
-serve the same purpose, but are often easier to use, shorter to write, and
-more intuitive to read. Instead of the <code>controller</code> automaton, we can also
-use the following:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">invariant motor.turn_on needs door.closed and emergency_button.released;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Each state/event exclusion invariant restricts an event, preventing it from
-happening in certain states. That is, the event is excluded from taking place
-in certain states. In this case, the <code>turn_on</code> event of the <code>motor</code>
-automaton needs the <code>door</code> to be in its <code>closed</code> location and the
-<code>emergency_button</code> to be in its <code>released</code> location, for the event to be
-allowed/enabled. For the states in which that condition doesn’t hold, the event
-is disabled.</p>
-</div>
-<div class="paragraph">
-<p>The invariant consists of two conditions. It can also be written as two
-separate state/event exclusion invariants, one for each condition:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">// Single state/event exclusion invariant.
-invariant motor.turn_on needs door.closed and emergency_button.released;
-
-// Multiple state/event exclusion invariants.
-invariant motor.turn_on needs door.closed;
-invariant motor.turn_on needs emergency_button.released;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The second and third invariants lead to the same behavior as the first combined
-invariant. The second invariant ensures that the event can only take place when
-the door is closed, while the third invariant ensures that the event can only
-take place when the emergency button is released. The second and third
-invariants each indicate a necessary condition that must hold for the event to
-be allowed/enabled. Together, they require that both conditions hold, for the
-event to be allowed/enabled. If one of the conditions doesn’t hold, the event
-will be disabled.</p>
-</div>
-<div class="paragraph">
-<p>The <code>door</code> is either <code>opened</code> or <code>closed</code>. So far, we’ve required that
-the door is closed to allow the motor to be turned on. We can also specify it
-the other way around: to disallow the motor to be turned on, while the door is
-opened:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">// State/event exclusion invariant to specify when event is allowed/enabled.
-invariant motor.turn_on needs door.closed;
-
-// State/event exclusion invariant to specify when event is disallowed/disabled.
-invariant door.opened disables motor.turn_on;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Both invariants have the exact same effect. The first invariant only allows the
-motor to be turned on while the door is closed, which means that it disallows
-the motor to be turned on in all other situations, namely when the door is
-opened. And that is exactly what is specified by the second invariant: when the
-door is opened, turning the motor on is disallowed/disabled. In general,
-state/event exclusion invariants can always be specified as a positive form
-(allowed/enabled) and a negative form (disallowed/disabled). It is up to the
-modeler to choose, based on considerations such as personal preference and
-readability. Consider the following four alternative forms:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">// Single state/event exclusion invariant for enabling the event.

-invariant emergency_button.pushed disables motor.turn_on;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Each of the four forms has the exact same effect, but is written in a different
-way.</p>
-</div>
-<div class="paragraph">
-<p>We already saw earlier that for state/event exclusion invariants that
-introduce necessary conditions for an event to be enabled (the <code>needs</code>
-variant), the conditions can be combined using an <code>and</code> operator to form a
-combined condition, for a single invariant.</p>
-</div>
-<div class="paragraph">
-<p>Here, we also see how in a similar way, state/event exclusion invariants that
-introduce sufficient conditions for an event to be disabled (the <code>disabled</code>
-variant) can be combined. Each of them individually has a condition, that if
-satisfied disables the event, regardless of the other invariants. So, if one of
-them disables the event, the event is disabled. To combine such invariants into
-a single invariant, the conditions need to be combined using an <code>or</code>
-operator, as shown above.</p>
-</div>
-<div class="paragraph">
-<p>It may occur that multiple events need to be disabled for the same conditions.
-Instead of writing multiple invariants with the same conditions, one for each
-event, they can also be combined:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">// Two separate invariants with same condition, for different events.

-</div>
-</div>
-<div class="paragraph">
-<p>The first two invariants have the same condition, but restrict different
-events. The third invariant has the same condition, but restricts both events.
-In general, for all state/event invariants, multiple events may be given, if

-Tuples are used for keeping several (related) kinds of data together in one

-A list is an ordered collection of values (called <em>elements</em>) of a same type.
-Lists can be used to model anything where duplicate values may occur or where
-order of the values is significant. Examples are customers waiting in a shop,
-process steps in a recipe, or products stored in a warehouse. Consider the
-following:</p>
-</div>
-<div class="listingblock">

-<pre class="CodeRay highlight"><code data-lang="cif">disc list int x = [7, 8, 3];</code></pre>

-</div>
-<div class="paragraph">
-<p>
-</p>
-</div>
-<div id="lang-tut-values-list-literal" class="paragraph">
-<p>Variable <code>x</code> has a list of integers as its value. In this case, its initial
-value is a literal list with three integer elements. Lists are ordered
-collections of elements. <code>[7, 8, 3]</code> is thus a different list as
-<code>[8, 7, 3]</code>. Lists are empty by default, and they may have duplicate
-elements:</p>

-<div class="listingblock">

-<pre class="CodeRay highlight"><code data-lang="cif">disc list int x1; // Implicitly empty list.
-disc list int x2 = []; // Explicitly empty list.
-disc list int x3 = [1, 2, 1, 2, 2]; // Duplicate elements in a list.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>
-
-Since lists are ordered, there is a first element and a last element (unless
-the list is empty). An element can be obtained by <em>projection</em>, usually called
-<em>indexing</em> for lists:</p>
-</div>
-<div class="listingblock">

-edge ... do x[0] := 5; // the first element of 'x' is replaced by '5'</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The first three edges obtain specific elements of the list, and assign them to
-variable <code>i</code>. The first element is obtained using <em>index</em> or <em>offset</em> <code>0</code>,
-the second element using index <code>1</code>, etc. The index of the last element is the
-length of the list (the number of elements in the list), minus one. Indexing
-does not change the value of variable <code>x</code>. The fourth edge is invalid, as
-the fourth element (index <code>3</code>) of variable <code>x</code> is used, which does not
-exist. The fifth edge replaces only the first element (index <code>0</code>) of list
-<code>x</code>, while keeping the remaining elements as they are. It is also allowed to

-</div>
-</div>
-<div class="paragraph">
-<p>Negative indices start from the back of the list, rather than from the front.
-Index <code>-1</code> thus always refers to the last element, <code>-2</code> to the second to

-that is out of range of available elements, results in an error. To obtain a
-non-negative index from a negative index, add the negative index to the length
-of the list: <code>3 + -1 = 2</code>, <code>3 + -2 = 1</code>, and <code>3 + -3 = 0</code>. The following

-Besides obtaining a single element from a list, it is also possible to obtain
-a sub-range of the elements of a list, called a <em>slice</em>. Slicing also does not
-change the contents of the list. It results in a copy of a contiguous
-sub-sequence of the list. The result of a slice operation is again a list, even
-if the slice contains just one element, or no elements at all. Slicing requires
-two indices: the index of the first element of the sub-range (inclusive), and
-the index of the last element of the sub-range (exclusive). Both indices may be
-omitted. If the start index is omitted, it defaults to zero. If the end index
-is omitted it defaults to the length of the list. If the begin index is equal
-to or larger than the end index, the slice is empty. Similar to indexing,
-negative indices may be used, which are relative to the end of the list rather
-than the start of the list. Indices that are out of bounds
-<a href="http://en.wikipedia.org/wiki/Saturation_arithmetic">saturate</a> to those
-bounds. Some examples:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">disc list int x = [7, 8, 3, 5, 9];

-x[2:7] // [3, 5, 9] Slice that excludes the first two elements.
-x[1:] // [8, 3, 5, 9] Slice that excludes the first element.
-x[:-1] // [7, 8, 3, 5] Slice that excludes the last element.
-x[:] // [7, 8, 3, 5, 9] Slice includes all elements (is equal to 'x').</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The first slice takes the third (index <code>2</code>) and fourth (index <code>3</code>)
-elements. The begin index (<code>2</code>) is thus included, the end index (<code>4</code>) is
-not. The second slice starts at the same index, but extends to the sixth
-element (index <code>7</code>). Since there are only five elements, the index is
-saturated (or clamped) to the end of the list. The results is that all but the
-first two elements are included. The third slice excludes the first element
-(index <code>0</code>), by starting at index <code>1</code>. It omits the end index, meaning that
-the entire remainder of the list is kept, and only the first element is not
-included. The fourth slice begins at the beginning of the list, as the begin
-index is omitted. It continues until the last element of list, which it
-excludes. It thus excludes a single element from the end of the list. The fifth
-slice includes all elements, as both the begin and end index are omitted. The
-slice is thus identical to the list in <code>x</code>. The following figure graphically
-represents the slices:</p>

-A set is an unordered collection of values (called <em>elements</em>) of a same type.
-Each element value either exists in a set, or it does not exist in a set. Each
-element value is unique, as duplicate elements are silently discarded. Consider
-the following:</p>
-</div>
-<div class="listingblock">
-<div class="content">

-disc set int x3 = {8, 3, 7, 3}; // Duplicates ignored (same as 'x2').
-disc set int x4 = {}; // Empty set.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>
-
-Variable <code>x1</code> has a set of integers as its value. In this case, its initial
-value is a literal set with three integer elements. As sets are unordered
-collections of elements, <code>{3, 7, 8}</code> is the same set as <code>{8, 3, 7}</code>, and
-thus variables <code>x1</code> and <code>x2</code> have the same initial values. Since elements
-in a set are unique, set <code>{8, 3, 7}</code> is equal to the set <code>{8, 3, 7, 3}</code>,
-and thus variables <code>x2</code> and <code>x3</code> have the same initial values. For
-readability, elements in a set are normally written in increasing order, for
-example <code>{3, 7, 8}</code>. Variable <code>x4</code> has an empty set as initial value, which
-is also the default initial value for sets.</p>
-</div>
-<div class="paragraph">
-<p>
-The <em>union</em> of two sets results in a set that contains the combined elements of
-both sets. You can think of the resulting set containing the elements that are
-in the one set <code>or</code> in the other set (or in both of them). Since sets never
-contain duplicates, common elements are present only once in the resulting set:</p>

-<p>Since sets are unordered, both answers are possible, and represent the same

-
-A dictionary is an unordered collection of <em>keys</em> and associated <em>values</em>. A
-key with its associated value is called a key/value <em>pair</em>. Consider the
-following:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">disc dict(string:int) age = {"eve": 32, "john": 34, "adam": 25};</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>
-
-Variable <code>age</code> has as value a dictionary consisting of pairs of strings
-(the keys) and integers (the values). In this example, each string represents
-a person’s name, and each integer represents the age of that person. Variable
-<code>age</code> is initialized with a literal dictionary, containing three key/value
-pairs. You can think of the dictionary as storing the information that <code>eve</code>
-is <code>32</code> years old, or that the age of <code>eve</code> is <code>32</code>.</p>
-</div>
-<div class="paragraph">
-<p>As with sets, dictionaries are unordered. The order of the key/value pairs is
-irrelevant, <code>{"eve": 32, "adam": 25}</code> is the same dictionary as
-<code>{"adam": 25, "eve": 32}</code>. For readability, key/value pairs of dictionary
-literals are normally written in increasing order of their keys.
-<code>{"adam": 25, "eve": 32}</code> is thus preferred over <code>{"eve": 32, "adam": 25}</code>,
-as <code>adam</code> goes before <code>eve</code> in a phone book.</p>
-</div>
-<div class="paragraph">
-<p>Dictionary literals are often written using multiple lines, to get two
-'columns' for the keys and values, which can improve readability:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">disc dict(string:int) age = {"eve": 32,
- "john": 34,
- "adam": 25};</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The default value for dictionary types, is an empty dictionary. The following
-two variables thus have the same initial value:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">disc dict(string:int) x1 = {}; // Explicitly initialized as empty.
-disc dict(string:int) x2; // Implicitly initialized as empty.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Every key of a dictionary is unique, but they may be associated with the same
-value. For the above example with ages, the names (keys) are used to uniquely
-identify people, but multiple people may have the same age (values). It is not
-allowed to have the same key twice, in a dictionary literal, regardless of
-whether they map to the same value or to different values:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">disc dict(int:int) x1 = {1: 2, 1: 2}; // Invalid due to duplicate key '1'.
-disc dict(int:int) x2 = {1: 2, 1: 3}; // Invalid due to duplicate key '1'.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The values of a dictionary can be obtained by <em>projection</em> on that dictionary,
-using the keys:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">disc dict(string:int) age = {"adam": 25, "eve": 32, "john": 34};

-edge ... do i := age["carl"]; // error (there is no "carl" key)</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Projection using a key that exists in the dictionary, results in the associated
-value. Projection using a key that does not exist in the dictionary, leads to
-a runtime error.</p>
-</div>
-<div class="paragraph">
-<p>It is possible to modify single elements of a dictionary, as follows:</p>

-edge ... do age["bob"] := 47; // Adds a new key/value pair.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The age of <code>eve</code> is changed from <code>32</code> to <code>33</code>. The age is thus replaced
-by a new age. The age of <code>bob</code> is set to <code>47</code>. Since there was no key/value

-<h4 id="tut-reuse1-chapter-constants">Constants</h4>
-<div class="paragraph">
-<p>
-Through the use of <em>constants</em>, fixed values can be given a name. Using
-constants, it is easy to change certain fixed values. If the constant is
-used consistently throughout the model, the value needs to be changed only in
-one place. Constants can thus make it easier to keep the model consistent.</p>
-</div>
-<div class="paragraph">
-<p>Consider the following CIF specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">const int STEP = 2;

- disc int position = 0;
- event move;
-
- location:
- initial;
- edge move when position < TARGET do position := position + STEP;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>In this example, the <code>movement</code> automaton keeps track of the <code>position</code> of
-an object. The object starts at position <code>0</code>. It can <code>move</code> until it
-reaches its target position. The target position is <code>100</code>. Rather than using
-<code>position < 100</code> as guard, the value <code>100</code> is stored in a constant named
-<code>TARGET</code>. The constant can then be used instead the value <code>100</code>. Similarly,
-the step size of the object is stored in a constant named <code>STEP</code>.</p>
-</div>
-<div class="paragraph">
-<p>Constants have a name, which by contention is usually written using upper case
-letters. Using a constant instead of a fixed value makes it more clear what
-that value represents. For instance, by using <code>position < TARGET</code> rather than
-<code>position < 100</code>, the intention of the guard condition is more clear. Using a
-constant can thus enhance readability.</p>
-</div>
-<div class="paragraph">
-<p>Another benefit of constants, is that they can be used multiple times in the
-same model:</p>

- location:

- edge forward when position < TARGET do position := position + STEP;
- edge backward when position > 0 do position := position - STEP;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>In this modified example it is possible for the object to perform <code>forward</code>

-changed by changing the value of the constant. Without using a constant, the
-speed would have to be changed separately for each edge.</p>
-</div>

-It is usually easier to use relative model time, i.e. a certain amount of time
-passes after a certain event. This is where <em>continuous variables</em> are ideal.
-A continuous variable is a variable that changes value automatically, as time

-of continuous variable <code>t</code> is reset to <code>0</code> using an assignment. As a result
-of this reset, <code>t</code> will be <code>0</code> when the automaton enters the <code>producing</code>
-location. The edge for the <code>finished</code> event indicates that the event can only
-happen when <code>t >= 3</code> holds. This condition will hold after three time units.
-This means that automaton <code>machine</code> remains in the <code>producing</code> location for
-three time units, before going to the <code>idle</code> location. It will thus always

-<p>The <code>producer</code> keeps track of the identification number (variable <code>nr</code>) of
-the current product, and provides products to either the first consumer
-(event <code>provide1</code>) or the second consumer (<code>provide2</code>). Both consumers
-have an identification number of their current product as well (variable
-<code>nr</code> in the consumer automata). Initially, the consumers don’t have a
-product, as indicated by value <code>-1</code>. When a consumer gets a new product, it
-looks up the identification number of the product at the producer, and stores
-it locally. The producer then moves on to the next product, by increasing its
-current identification number.</p>
-</div>
-<div class="paragraph">
-<p>We can identify two problems in this model.</p>
-</div>
-<div class="paragraph">
-<p>The first problem is that we need two events in order for the producer to
-provide products to <em>either</em> the one consumer <em>or</em> the other consumer. If we
-used only one event, both consumers would need to use that event, have the
-event in their <a href="#tut-basics-chapter-alphabet">alphabet</a>, and would thus have
-to simultaneously participate in the
-<a href="#tut-basics-chapter-synchronizing-events">synchronization</a>. A consequence of
-having an event per consumer, is that the <code>producer</code> automaton has both
-events on its edge. Adding a third consumer entails having to add another
-event, as well as having to modify the edge of the <code>producer</code> automaton. This
-is not a nice scalable solution.</p>
-</div>
-<div class="paragraph">
-<p>The second problem is that the consumer refers directly to the <code>nr</code> variable
-of the <code>producer</code> automaton. This introduces a very tight coupling between
-the producer and the consumers. It exposes the <code>nr</code> variable of the
-<code>producer</code> to the consumers, making it more difficult to change the producer
-without changing the consumers.</p>
-</div>
-<div class="paragraph">
-<p>
-
-Both these problems can be solved by using <em>channels</em>. Channels are a special
-form of events, that can be used to communicate or transmit data from a
-<em>sender</em> to a <em>receiver</em>. In our example, data that is communicated are the
-identification numbers of the products, the producer is the sender, and the
-consumers are the receivers.</p>
-</div>
-<div class="paragraph">
-<p>Channels require one or more potential senders, and one or more potential
-receivers. Automata cannot be both sender and receiver for a single channel.
-They may however be a sender for one channel, and a receiver for another
-channel. For every transition, exactly one of the senders and exactly one of
-the receivers participate. The sender sends a value, and the receiver
-receives that value. This type of communication is often called channel
-communication or <em>point-to-point</em> communication, as the data is communicated
-from one point (the sender) to another point (the receiver).</p>
-</div>
-<div class="paragraph">
-<p>Multiple automata that synchronize over the same event perform a transition
-together. Similarly, a sender and receiver that together perform a
-channel communication, perform a transition together. In both cases,
-all automata involved take their respective edges <em>synchronously</em>
-(simultaneously).</p>
-</div>
-<div class="paragraph">
-<p>Channels are ideally suited for modeling product flows, or more generally the
-movement of physical entities through a system. Physical objects usually don’t
-duplicate themselves or spontaneously stop to exist. This fits nicely with
-channels, where data is communicated or passed along from exactly one sender
-to one receiver. In our example, product produced by the producer are
-physically provided to one of the consumers.</p>
-</div>
-<div class="paragraph">
-<p>The following CIF specification models the above example using channels:</p>

-The <code>provide1</code> and <code>provide2</code> events have been replaced by a single
-channel named <code>provide</code>. Channels are declared similar to events, but have a
-<a href="#tut-values-chapter-types-values-exprs">data type</a> that indicates the type
-of <a href="#tut-values-chapter-types-values-exprs">values</a> that are communicated

-<p>
-
-The <code>producer</code> now uses the channel on its edge, instead of the two events.
-The exclamation mark (<code>!</code>) after the channel name means that the producer
-is sending over the channel. After the exclamation mark, the value that the
-producer sends is given. In this case, the producer sends the identification
-number of its current product.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-
-The edges of the consumers have been modified as well. The channel is used
-with a question mark (<code>?</code>) after the channel name, indicating that the
-consumers receive over the channel. The received value, which is available as
-the <code>?</code> variable in the update, is directly assigned to the <code>nr</code> variable
-of the consumer.</p>
-</div>
-<div class="paragraph">
-<p>By using channels, we no longer need multiple events, and the producer does not
-need to be modified if another consumer is added. This makes the model scalable
-to varying amount of consumers. Furthermore, the consumers now use the <code>?</code>
-variable to obtain the received value, and no longer need direct access to the
-variables of the producer. This makes it easier to modify the producer
-without having to also modify the consumers.</p>

-Besides channels that communicate data, it is also possible to use dataless
-channels. A channel that does not communicate any data, is declared with the
-<code>void</code> type. Dataless channels are also called <code>void</code> channels. When using
-dataless channels, the sender does not provide a value to send over the

-<p>Dataless channels are used in the same situations as 'normal' channels,

-<div class="paragraph">
-<p>If an event parameter is actually a channel (it has a data type), it may also
-be called a <em>channel parameter</em>. By default, a channel parameter can be used to
-send, receive, or synchronize. However, it is also possible to restrict the
-allowed usages. By putting certain event usage restriction flags after the name
-of the channel parameter, only those usages are allowed. The available flags
-are <code>!</code> to allow sending, <code>?</code> to allow receiving, and <code>~</code> to allow
-synchronizing. Duplicate flags are not allowed, the <code>!</code> should be before the
-<code>?</code> flag, and the <code>!</code> and <code>?</code> flags should be before the <code>~</code> flag.</p>
-</div>
-<div class="paragraph">
-<p>By restricting the usages, you can immediately see how a channel parameter is
-used within the automaton definition, as only the usages indicates by the
-parameter are allowed. It serves as sort of documentation of the intention of
-the channel parameter. This is much simpler than finding the actual usages of
-the parameter in the automaton. However, note that the parameter indicates the
-allowed usages, and doesn’t guarantee that the event/parameter is actually used
-at all.</p>
-</div>
-<div class="paragraph">
-<p>Another benefit of restricting the usages, is that it makes it possible to spot
-mistakes. You might for instance use a channel parameter on an edge (e.g.
-<code>edge e</code>), but forget to include the send part (e.g. <code>edge e!1</code>). If the
-parameter only allows sending, the accidental synchronization (<code>edge e</code>) is
-reported as an invalid use. Without the usage checking, you might not encounter
-the problem until for instance simulation, where it is much more difficult to
-find the cause.</p>

-For large CIF specifications with many automata, it can be beneficial to add

-<p>The two CIF specifications together form a simplified producer/consumer system.

-<div class="paragraph">
-<p>
-Supervisory controller synthesis (or supervisor synthesis, or just synthesis)
-is a generative technique, where one derives a supervisory controller from a
-collection of plants and requirements. Synthesis allows to focus on the <em>what</em>,
-i.e. which requirements should hold, rather than on the <em>how</em>, i.e. how to
-implement this in a controller.</p>
-</div>
-<div class="paragraph">
-<p>
-
-</p>
-</div>
-<div id="lang-tut-extensions-synthesis-plant-req-sup" class="paragraph">
-<p>The <em>plants</em> describe capabilities or behavior of a physical system 'as is',
-without any integrated control. They represent the available behavior of the
-uncontrolled system. <em>Requirements</em> model (a part of) the functions a system is
-supposed to perform. They represents behavior that is allowed in the controlled
-system, or more precisely, they specify the behavior that is not allowed in the
-controlled system. In other words, requirements restrict the behavior of the
-plants, to ensure that only the desired behavior remains. The goal of
-supervisory controller synthesis is to compute a supervisory controller (or
-<em>supervisor</em>) that enforces the requirements, assuming the behavior of the
-plants, additionally preventing deadlock and livelock, and without restricting
-the system any further than is required.</p>
-</div>
-<div class="paragraph">
-<p>It is beyond the scope of the CIF language tutorial to go into the details of
-supervisory controller synthesis. However, CIF has several features that are
-used solely of modeling systems for the purpose of supervisory controller
-synthesis:</p>

-<h5 id="lang-tut-extensions-synthesis-autkind">Automaton kinds</h5>
-<div class="paragraph">
-<p>For supervisory controller synthesis, different kinds of automata are treated
-in different ways. Regular automata, as used in the language tutorial so far,
-are specified using only the <code>automaton</code> keyword. Regular automata do not
-specify a kind for supervisory controller synthesis, and are therefore
-sometimes also referred to as kindless automata. Synthesis tools typically
-require knowledge about the purpose of each of the automata, and therefore
-don’t support regular automata.</p>
-</div>
-<div class="paragraph">
-<p>For supervisory controller synthesis, three different kinds of automata are
-available: plant automata, requirement automata, and supervisor automata. These
-automata are identical to regular automata, except for the keywords used to
-declare their intent. The <code>automaton</code> keyword is preceded or replaced by the
-<code>plant</code>, <code>requirement</code>, or <code>supervisor</code> keyword respectively.</p>
-</div>

-<h5 id="lang-tut-extensions-synthesis-invkind">Invariant kinds</h5>
-<div class="paragraph">
-<p>Similar to automata, different kinds of invariants are treated in different
-ways for supervisory controller synthesis. Invariants can be declared as plant,

-<code>invariant</code> keyword with a <code>plant</code>, <code>requirement</code>, or <code>supervisor</code>
-keyword respectively.</p>

-<div id="lang-tut-extensions-synthesis-invkind-implicit" class="paragraph">

-result in a warning. To get rid of the warning, explicitly specify the
-supervisory kind of the invariant.</p>

-<div class="paragraph">
-<p>The first invariant has no explicit supervisory kind specified, and therefore

-<code>plant</code> kind. It is also a plant invariant, but due to the explicit kind
-specification, there is no warning. The third and last invariant is identical

-</div>
-<div class="paragraph">
-<p>There are two forms of invariants:
-<a href="#tut-data-chapter-stat-invariants">state invariants</a> and

-<div class="paragraph">
-<p>The counter can be incremented and decremented. The plant invariant specifies

-<h5 id="lang-tut-extensions-synthesis-evtctrl">Event controllability</h5>
-<div class="paragraph">
-<p>Supervisory controller synthesis distinguishes two kinds of
-<a href="#lang-tut-basics-automata-events">events</a>: controllable events and
-uncontrollable events.</p>
-</div>
-<div class="paragraph">
-<p>Uncontrollable events are events that a supervisor can not prohibit, and are
-usually related to sensors. A typical example are events that indicate that a
-button has been pushed or released. A button is essentially a sensor that is
-on if the user pushes the button, and off if the user doesn’t push it. The
-supervisor can not prevent a user from physically pushing or releasing a
-button, and can also not determine when the user pushes or releases it. The
-supervisor thus also can not prevent the events from occurring.</p>
-</div>
-<div class="paragraph">
-<p>Another example is an event that indicates that a moving part has reached its
-outer position (limit sensor turns on). If the part reaches its outer position,
-the event will occur. The supervisor can not control the sensor, as it is
-physically linked to the position of the moving part.</p>
-</div>
-<div class="paragraph">
-<p>Controllable events may be restricted by a supervisor, and are usually related
-to actuators. Typical examples are events used to turn a motor on or off, to
-turn a lamp on or off, or to change the direction of movement.</p>
-</div>
-<div class="paragraph">
-<p>Even though a supervisor may not be able to control a limit sensor directly,
-and thus restrict the corresponding events, it may be able to influence it
-indirectly. For instance, a motor may be available that makes it possible for
-the part to move. That motor may then be controlled using controllable on and
-off events. Stopping the motor then makes the part stop moving, ensuring that
-the part never reaches its outer position, indirectly preventing the limit
-sensor from turning on, and the corresponding event from happening.</p>
-</div>
-<div class="paragraph">
-<p>Events and <a href="#tut-channels-chapter-intro">channels</a> in CIF are declared
-using the <code>event</code> keyword. For controllable events, the <code>event</code> keyword
-may be preceded or replaced by the <code>controllable</code> keyword. Similarly,
-for uncontrollable events, the <code>event</code> keyword may be preceded or replaced
-by the <code>uncontrollable</code> keyword. Similar to event declarations, for
-<a href="#lang-tut-reuse2-aut-def-param-kinds-event">event parameters</a> the
-<code>event</code> keyword may by preceded or replaced by the <code>controllable</code> or
-<code>uncontrollable</code> keyword, for controllable and uncontrollable event
-parameters respectively.</p>
-</div>
-<div class="paragraph">
-<p>As a convention, controllable events are given names that start with <code>c_</code>,
-and uncontrollable events are given names that start with <code>u_</code>. This allows
-them to be highlighted in different colors.</p>

-<h5 id="lang-tut-extensions-synthesis-marked">Marker predicates</h5>
-<div class="paragraph">
-<p>Marking is very weak form of liveness, and is used by supervisory controller
-synthesis to prevent livelocks, to ensure progress. It is also used to prevent
-deadlocks. A supervisor per definition ensures that a marked state can always
-be reached, for the entire system. A system is marked if all its automata are
-marked. An automaton is marked if its active location is a marked location. In
-literature, marked location are also called <em>safe</em> locations. Note that
-deadlock in marked states is not prevented, as a marker state (the state
-itself) can be reached by not taking any transition. In literature, marked
-deadlock states are also called <em>final</em> states.</p>
-</div>
-<div class="paragraph">
-<p>Marking can be specified using <em>marker predicates</em>. Locations can be marked
-using the <code>marked</code> keyword, as follows:</p>

-<p>In this example location <code>off</code> is both initial and marked, while location

-<a href="#tut-data-chapter-init-preds">initialization predicates</a>, as by default,

-Marker predicates can be specified in locations, automata,
-<a href="#tut-reuse2-chapter-groups">groups</a>, and the top level of the specification
-(which can be seen as a group), similar to initialization predicates.</p>

-<p>An integer literal. Defined by the regular expression: <code>0|[1-9][0-9]*</code>.
-Integers thus consist of numeric digits. Only for the number <code>0</code> may an
-integer literal start with <code>0</code>. E.g. <code>02</code> is invalid.</p>

-<p>A real literal. Defined by the regular expression:
-<code>(0|[1-9][0-9]*)(\.[0-9]+|(\.[0-9]+)?[eE][\-\+]?[0-9]+)</code>.
-Simple double literals consist of an integer literal followed by
-a period (<code>.</code>) and some numeric digits. Double literals using scientific
-notation start with either an integer literal or a simple double literal.
-They then contain either an <code>e</code> or <code>E</code>, followed by the exponent.
-The exponent consists of numeric digits, optionally preceded by <code>+</code> or <code>-</code>.</p>

-<dd>
-<p>A string literal. Defined by the regular expression:
-<code>\"([^\\\"\n]|\\[nt\\\"])*\"</code>. String literals are enclosed in double
-quotes (<code>"</code>). String literals must be on a single line and must thus not
-include new line characters (<code>\n</code>, Unicode U+0A). To include a double quote
-(<code>"</code>) in a string literal, it must be escaped as <code>\"</code>. Since a
-backslash (<code>\</code>) serves as escape character, to include a backslash in a string
-literal it must be escaped as <code>\\</code>. To include a tab character in a string
-literal, use <code>\t</code>. To include a newline in a string literal, use <code>\n</code>.</p>

-<div class="paragraph">
-<p>CIF supports spaces, tabs, and new line characters as whitespace.
-Whitespace is ignored (except in string literals), but can be used to separate
-tokens as well as for layout purposes. The use of tab characters is allowed,
-but should be avoided if possible, as layout will be different for text
-editors with different tab settings. You may generally format a CIF
-script as you see fit, and start on a new line when desired.</p>

-The CIF to yEd transformer can be used to transform CIF specifications to
-yEd diagrams. Several <a href="#tools-cif2yed-diagram-kinds">kinds of diagrams</a>
-can be generated. These diagrams can be used to better understand the
-specification, to communicate the specification to other, or to be included in
-reports.</p>
-</div>
-<div class="paragraph">
-<p>The
-<a href="http://www.yworks.com/en/products/yfiles/yed/">yEd Graph Editor</a>
-is an
-application that can be used to view, create, edit, arrange, import and export
-various kinds of diagrams. It is freely available and runs on Windows, Linux,
-and Mac OS X.</p>
-</div>
-<div class="paragraph">
-<p>The yEd diagrams are generated as
-<a href="http://graphml.graphdrawing.org/">GraphML</a>
-files (<code>*.graphml</code> files), using yEd specific extensions to specify the
-graphical representation.</p>

-<h5 id="tools-starting-the-transformation">Starting the transformation</h5>
-<div class="paragraph">
-<p>The transformation can be started in the following ways:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>In Eclipse, right click a <code>.cif</code> file in the 'Project Explorer' tab
-or 'Package Explorer' tab and choose
-<b class="menuref">Convert CIF to yEd diagram…​</b>.</p>
-</li>
-<li>
-<p>In Eclipse, right click an open text editor for a <code>.cif</code> file and choose
-<b class="menuref">Convert CIF to yEd diagram…​</b>.</p>
-</li>
-<li>
-<p>Use the <code>cif2yed</code> tool in a
-ToolDef script. See the
-<a href="#tools-scripting-chapter-intro">scripting documentation</a> and
-<a href="#tools-scripting-chapter-tools">tools overview</a> page for details.</p>

-<h5 id="tools-cif2yed-options">Options</h5>
-<div class="paragraph">
-<p>Besides the general application options, this application has the following
-options:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p><em>Input file path</em>: The absolute or relative local file system path to the
-input CIF specification.</p>
-</li>
-<li>
-<p><em>Output file path</em>: The absolute or relative local file system path to the
-output yEd/GraphML diagram file. If not specified, defaults to the input file
-path, where the <code>.cif</code> file extension is removed (if present), and a
-<code>.kind.graphml</code> file extension is added. For the added default file
-extension, <code>kind</code> is replaced by the diagram kind (see other option), e.g.
-<code>model</code>, resulting in file extension <code>.model.graphml</code>. If multiple
-diagrams are generated, the output file path may not be specified. In such
-cases, either use the implicit/default file names, or generate one diagram at
-a time, allowing you to specify an explicit output file path for each of
-them.</p>
-</li>
-<li>
-<p><em>Diagram kinds</em>: The kinds of diagrams to generate. The default is to
-generate all the different kinds of diagrams. See the
-<a href="#tools-cif2yed-diagram-kinds">Diagram kinds</a> section for details.</p>
-</li>
-<li>
-<p><em>Syntax highlighting</em>: Whether to apply syntax highlighting (if option is
-enabled), or use plain text (if option is disabled). By default, syntax
-highlighting is enabled. For large diagrams, disabling syntax highlighting
-can significantly improve the performance, when displaying the diagrams in
-yEd.</p>
-</li>
-<li>
-<p><em>Transparent edge labels</em>: Enable option to use a transparent background for
-edge labels. Disable option to use a light gray background. By default, the
-option is disabled (a light gray background is used). See the
-<a href="#tools-cif2yed-layout">Layout</a> section below for further details.</p>

-<p>Each data usage in a component not related to a declaration (variable,

-<p>Event parameters of component instantiations are coupled to the actual event

-</div>
-<div class="ulist">
-<ul>
-<li>
-<p><em>BDD output mode</em>: This option can be used to control how the BDDs are

-section below.</p>
-</li>
-<li>
-<p><em>BDD variable order</em>: CIF variables and automata are represented using one or

-an internal operation cache. This option can be used to set the ratio of the
-size of the operation cache of the BDD library to the size of the node table
-of the BDD library. For instance, a ratio of <code>0.1</code> means that the size of
-the operation cache is 10% of the size of the node table. The operation cache
-ratio must be in the range [0.01 .. 1000]. The default ratio is 1.0. This

-<a href="#tut-data-chapter-stat-evt-excl-invariants">state/event exclusion invariants</a>, and
-<a href="#lang-tut-extensions-synthesis-autkind">requirement automata</a>.</p>
-</div>
-<div class="paragraph">
-<p>State invariants are global conditions over the values of variables (and
-locations of automata) that must always hold. Such requirements are sometimes
-also called mutual state exclusions. Here are some examples:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">requirement invariant x != 0 and not p.b;
-requirement invariant x > 5;

-requirement (3 <= x and x < = 5) or (2 <= y and y <= 7);
-requirement x = 1 => y > 2;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>State/event exclusion invariants or simply state/event exclusions are
-additional conditions under which transitions may take place for certain
-events. Here are some examples:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">requirement invariant buffer.c_add needs buffer.count < 5;
-requirement invariant buffer.c_remove needs buffer.count > 0;
-requirement invariant button.on = 1 disables lamp.c_turn_on;

-requirement p.x = 3 and p.y > 7 disables p.u_something;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Requirement automata are simply automata marked as <code>requirement</code>. They
-usually introduce additional state by using multiple locations or a variable.
-The additional state is used to be able to express the requirement. One common
-example is a counter. For instance, consider the following requirement, which
-prevents more than three products being added to a buffer:</p>
-</div>
-<div class="listingblock">

-<pre class="CodeRay highlight"><code data-lang="cif">requirement automaton counter:

- initial;
- marked;
-
- edge buffer.c_add do count := count + 1;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Another common example is a requirement that introduces ordering. For instance,
-consider the following requirement, which states that <code>motor1</code> must always be
-turned on before <code>motor2</code> is turned on, and they must always be turned off in
-the opposite order:</p>
-</div>
-<div class="listingblock">

-<p>Besides the explicit requirements, synthesis also prevents runtime errors. This

-<code>0 <= x and x <= 5 and 1 <= y and y <= 3</code> is

-<p>Internally, predicates are represented using

-(BDDs). The supervisor
-that is the output of synthesis, contains several predicates as well. For

-initialization predicate. The predicates represented as BDDs need to be
-represented as CIF predicates. There are multiple approaches to do this, and
-the <em>BDD output mode</em> option (see <a href="#tools-datasynth-options">options</a>
-section above), can be used to configure the approach to use.</p>
-</div>
-<div class="paragraph">
-<p>The first approach, which is also the default approach (named <code>normal</code>), is
-to use either
-<a href="http://en.wikipedia.org/wiki/Conjunctive_normal_form">Conjunctive Normal Form</a>
-(CNF) or
-<a href="http://en.wikipedia.org/wiki/Disjunctive_normal_form">Disjunctive Normal Form</a>
-(DNF) predicates. This

-systems), the CIF predicates are often intuitive, and can easily understood.
-The downside is that for larger systems, the CIF predicates often grow
-exponentially in size.</p>
-</div>
-<div class="paragraph">
-<p>The second approached (named <code>nodes</code>), is to represent the internal BDD nodes
-directly in CIF. The BDD is then more or less coded directly in CIF, using
-some constants and algebraic variables, and is evaluated using a BDD evaluation
-function. The benefit is that for larger systems, this representation remains
-relatively small, and at the very least doesn’t blow up nearly as much as the
-CNF and DNF representations. The downside to this approach, is that it leads to
-a supervisor that can not be easily understood by inspecting it. For this
-approach, several objects are created in the top level scope of the CIF
-specification. The names of these declarations all share a common prefix. The
-default prefix is <code>bdd</code>, but it can be changed using the
-<em>BDD output name prefix</em> option (see

-occur if the requirement automata and state/event exclusion invariants allow
-them.</p>
-</div>
-<div class="paragraph">
-<p>The synthesis algorithm does not restrict any uncontrollable events. Instead,

-<div class="paragraph">
-<p>If a variable in the uncontrolled system has a single initial value, and the

-</div>
-<div class="paragraph">
-<p>
-
-Calculations during synthesis often involve
-<a href="https://en.wikipedia.org/wiki/Reachability">reachability</a>.
-For instance,
-from which states is it possible to reach a marker state? To compute the states
-that can reach a marker state, the marker predicate of the input specification
-is used. The marker predicate indicates the states that are themselves marked.
-Then, the states are calculated that can reach one of those marked states, via
-a single transition. They are put together, to form the states that are marked
-or can be marked after one transition. By taking another such step, we can add
-the states that can reach a marked state via two transitions. We then have all

-</div>
-<div class="paragraph">
-<p>
-This form of reachability is called backward reachability, as it starts with
-some target (e.g. marked states), and goes backwards to find all states from
-which the target can be reached. Backward reachability can lead to states that
-could never be reached from an initial state, even in the uncontrolled system.
-This leads to two separate issues.</p>
-</div>
-<div class="paragraph">
-<p>The first issue is about unintuitive resulting supervisor guards. The
-resulting supervisor forbids certain transitions, by restricting controllable
-events. It among others forbids transitions that end up in states from which no
-marked state can be reached. However, if those forbidden states can never be
-reached from an initial state, there is no reason to restrict the controllable
-events in such cases. The guards of the resulting supervisor then appear to
-restrict the controllable events, while in fact the guard doesn’t impose a
-restriction for the controlled system. The supervisor simply doesn’t have the
-necessary information to know this.</p>
-</div>
-<div class="paragraph">
-<p>The second issue is about performance. Expanding unreachable states during
-backward reachability takes time and costs memory, while it has no useful
-effect on the resulting controlled system.</p>
-</div>
-<div class="paragraph">
-<p>
-The use of forward reachability can be a solution to both problems. Forward
-reachability starts with the initial states, and adds states reachable via one
-transitions, then via two transitions, then via three transitions, etc. This
-is repeated until all reachable states are found.</p>
-</div>
-<div class="paragraph">
-<p>By combining both forward and backward reachability, the supervisor knows about
-states that exist in the uncontrolled system (due to forward reachability) and
-about states that it should forbid (due to backward reachability). This leads
-to the supervisor only restricting transitions that are strictly necessary.
-However, both when using forward reachability and when not using it, the
-synthesized supervisor is safe, non-blocking, and maximally permissive. It is
-only the guards that are more complex than they might need to be, if forward
-reachability is not used. More complex guards are often less readable, and
-potentially more expensive to implement in an actual controller.</p>
-</div>
-<div class="paragraph">
-<p>By combining both forward and backward reachability, parts of the state space
-that are not relevant may not have to be expanded (as much), which may improve
-performance. However, computing the forward reachability may also take time
-and cost memory, thus reducing performance.</p>
-</div>
-<div class="paragraph">
-<p>It depends on the specification being synthesized whether enabling forward
-reachability increases or decreases performance. It also depends on the
-specification whether there is any benefit to using forward reachability for
-the guards of the supervisor. Forward reachability is disabled by default. It
-can be enabled using the <em>Forward reachability</em> option (see

-<p>Internally, predicates are represented using
-<a href="http://en.wikipedia.org/wiki/Binary_decision_diagram">Binary Decision Diagrams</a>
-(BDDs). CIF
-variables and automata are represented using one or more boolean variables
-(also called BDD variables or bits). For instance, a boolean CIF variable is
-represented using a single boolean/BDD variable, and a CIF variable of type
-<code>int[0..8]</code> is represented using four boolean/BDD variables (9 possible
-values, log<sub>2</sub>(9) ≈ 3.17). For each automaton with two or
-more locations, a location pointer variable is created, that represents the
-current or active location of that automaton. For instance, an automaton with
-three locations is represented using two boolean/BDD variables. Two boolean/BDD
-variables can represent 2<sup>2</sup> = 4 values, so one value is not
-used.</p>
-</div>
-<div class="paragraph">
-<p>The CIF variables and location pointer variables for the automata
-(together called synthesis variables) can be ordered. This ordering can
-significantly influence the performance of synthesis. Synthesis variables that
-have a higher influence on the result of predicates (simply put, occur more
-frequently in predicates) should generally be put earlier in the ordering.
-Furthermore, in general, strongly related synthesis variables (e.g. by
-comparison, integer computation, or assignment) should be kept closely together
-in the order. For two synthesis variables <code>x</code> and <code>y</code>, examples of
-predicates that introduce relations are <code>x = y</code> (by comparison) and
-<code>5 < x + y</code> (by integer computation), and examples of assignments that
-introduce relations are <code>x := y</code> and <code>x := y + 1</code> (both by assignment).</p>
-</div>
-<div class="paragraph">
-<p>For the initial variable ordering, it is possible to order the BDD variables
-per synthesis variable, or to interleave the BDD/boolean variables of some
-synthesis variables. This can significantly influences the performance of
-synthesis. Generally, strongly related synthesis variables should be
-interleaved.</p>

-<div class="paragraph">
-<p>The variables and automata are initially ordered randomly. If no

-<p>Furthermore, a custom initial order can be defined. Custom orders consist of

-<code>a</code>, with a discrete variable <code>x</code>, the absolute name of the variable is
-<code>a.x</code>. The <code>*</code> character can be used as wildcard in those names, and

-</div>
-<div class="paragraph">
-<p>Multiple names can be separated with <code>;</code> characters. The synthesis variables

-</div>
-<div class="paragraph">
-<p>Each name pattern in the order must match at least one variable or automaton.
-A variable or automaton may not be included more than once in the
-order. Every variable and automaton (with two or more locations) needs to be
-included in the order. It is not possible to specify new variables, as they
-are always directly after their corresponding old variables, and they are
-always interleaved.</p>
-</div>
-<div class="paragraph">
-<p>For instance, consider two automata: <code>a</code> and <code>b</code>, each with three
-variables of type <code>int[0..3]</code>: <code>x1</code>, <code>x2</code>, and <code>x3</code>. The automata have
-three locations each, so location pointers are created for them. We thus have
-six discrete variables: <code>a.x1</code>, <code>a.x2</code>, <code>a.x3</code>, <code>b.x1</code>, <code>b.x2</code>, and
-<code>b.x3</code>, and two location pointer variables: <code>a</code> and <code>b</code>. Consider the
-following custom order: <code>b*;a.x3,a.x1;a.x2,a</code>. Pattern <code>b*</code> matches
-location pointer variable <code>b</code> as well as the three discrete variables of
-automaton <code>b</code> (<code>b.x1</code>, <code>b.x2</code>, and <code>b.x3</code>). They are ordered in
-increasing alphabetic order, and are interleaved. Variables <code>a.x3</code> and
-<code>a.x1</code> are also interleaved, with <code>a.x3</code> before <code>a.x1</code>. Finally, variable
-<code>a.x2</code> is ordered before the location pointer for automaton <code>a</code>, and they
-are interleaved as well. This results in the following initial boolean/BDD

-<div class="paragraph">
-<p>One of the main properties of BDDs is that they employ full sharing. That is,
-if a part of a binary tree needs to be represented more than once, it is stored
-only once, and reused. This leads to BDDs being represented using directed
-acyclic graphs, rather than binary trees.</p>
-</div>
-<div class="paragraph">
-<p>The BDD library uses an operation cache to speed up synthesis. Whenever a
-certain operation is performed on one or more nodes of a BDD graph, the result
-is cached. If that same operation is performed again on the same nodes, the
-cached result is reused, if available. This way, repeated calculations can be
-prevented for shared sub-graphs.</p>
-</div>
-<div class="paragraph">
-<p>The operation cache is essential for the performance of the synthesis
-algorithm. With infinite caches, the operations are generally linear in the
-number of nodes used to represent the BDDs on which they are applied. Without
-caching, the computation time grows exponentially.</p>
-</div>
-<div class="paragraph">
-<p>Obviously, in practice we can’t have infinite caches, as a computer only has a
-finite amount of memory available. We thus need to work with finite caches.
-Whenever a new cached operation result doesn’t fit in the cache, an older
-result is overwritten, and will need to be recomputed if it is needed again.</p>
-</div>
-<div class="paragraph">
-<p>Increasing the cache size can significantly increase performance for large
-systems, as a cache that is too small is ineffective, and results in many
-operations needing to be repeated, that could have otherwise been obtained from
-the cache. However, a larger than needed cache may also significantly decrease
-performance, as a cache that is too large may no longer fit within CPU caches,
-leading to more expensive accesses to the main memory rather than e.g. L1/L2/L3
-caches.</p>
-</div>

-Synthesis, 'supervisor synthesis', or 'supervisory controller synthesis', is a
-generative technique, where one derives a (supervisor) automaton from a
-collection of plants and requirements. The resulting supervisor is maximally
-permissive under the conditions of being free of deadlocks, and always having
-the option of reaching a marked state.</p>
-</div>
-<div class="paragraph">
-<p>While there is only one true synthesis tool (the tool that actually derives a
-supervisor automaton from a collection of plant and requirement automata),
-other tools exist to support the process. These tools together form the
-<em>event-based synthesis toolset</em>.</p>
-</div>
-<div class="paragraph">
-<p>These tools use and modify the sequences of events that can be performed. This
-in contrast to state-based tools, which operate primarily on the
-<a href="#tools-cifsim-traces-state">state</a> of the system. Event sequences
-directly hook into language theory, which places these tools firmly in the
-language theory mathematical framework.</p>

-</div>
-<div class="paragraph">
-<p>To use the tool, enable creation of the <em>Synthesis Dump</em> file during

-<p>By double clicking the generated dump file, or by right-clicking the dump file

-</div>
-<div class="paragraph">
-<p>At the left, all automata with their initial location are shown. You can
-select a different supervisor state by changing these locations. At the top,
-in the middle, there are three buttons. The bottom button labeled <em>Search
-state</em> is used to search the information about a supervisor state selected at
-the left. The <em>Jump to initial state</em> button resets the automata locations
-to their initial state, useful when you want to start again. The middle button
-is disabled now, but allows you to go back to the previous state.</p>
-</div>
-<div class="paragraph">
-<p>At the right, a number of options are available in case the displayed
-information is not sufficient. These are explained later.</p>
-</div>
-<div class="paragraph">
-<p>Below the buttons and options is the report area, which just displays some

-<div class="content">
-<img src="./tools/eventbased/analysis_basic.png" alt="analysis basic">
-</div>
-</div>
-<div class="paragraph">
-<p>The report area changes to display the information about the selected state.
-It starts with the internal number of this state (<code>#0</code>), and its properties.
-The <code>initial</code> means this state is the initial state, <code>marked</code> means this
-state is marked. Then follows an explicit list of locations of every
-automaton. It is the same list as the selected locations at the left, but more
-compact. Then the analysis result is shown. This state exists in the
-supervisor, and has no outgoing edges. In other words, this state is the only
-state in the result. Below it, the edges removed by the requirements are
-listed, together with the name of the requirement automaton that disabled it.</p>
-</div>
-<div class="paragraph">
-<p>Not displayed here is the list of edges removed due to plant automata. These
-can be displayed by enabling the <em>Display disabled plant events</em> option at the
-top-right.</p>
-</div>
-<div class="paragraph">
-<p>If a state does have outgoing edges, these are displayed as well:</p>

-<p>State <code>#7</code> has one outgoing edge, leading to state <code>#9</code> using event
-<code>Sensor_In_Off</code>. The last line with the removed controllable events
-displays a removed edge because destination state <code>#8</code> was removed.</p>
-</div>
-<div class="paragraph">
-<p>If you want to know what states <code>#9</code> or <code>#8</code> are, you can enable the
-<em>Display full state</em> at the top-right, and the tool will display the full
-list of automaton locations with each state, just like the first line in the
-report. You can also go to these states, by double-clicking at the blue area.
-If you click at removed state <code>#8</code> you get a display like:</p>

-<img src="./tools/eventbased/analysis_removed.png" alt="analysis removed">

-<p>As expected, the analysis tools displays that the state was removed,
-apparently because it was not co-reachable. Again you get the list of removed
-edges from this state, as an aid to decide which requirement should be
-checked, if this was not expected.</p>
-</div>
-<div class="paragraph">
-<p>The final screenshot shows what is displayed if a state is removed because

-<div class="content">
-<img src="./tools/eventbased/analysis_chain.png" alt="analysis chain">
-</div>
-</div>
-<div class="paragraph">
-<p>This is an example from a bigger system, where the supervisor is empty. The
-analysis of the initial state reveals that it was removed due to a removal of
-a chain of other states. State <code>#24</code> was removed due to a requirement
-(reading from bottom to top), which caused the chain of states <code>#9</code>, <code>#2</code>,
-and eventually <code>#0</code> to be removed.</p>
-</div>
-<div class="paragraph">
-<p>Removed edges with controllable events are not displayed here, since these
-have no influence to the disappearing of the states. If you want, you can
-display them by toggling the <em>Always display disabled controllable events</em>
-option at the top-right.</p>
-</div>
-<div class="paragraph">
-<p>In this example, the number of states in the chain to the disabling
-requirement was 4 states. This chain can be longer. Usually the middle part
-is not that interesting and it is omitted from the display, but if you want to
-see them, you can increase the number of displayed states at the top-right
-(which is by default <code>5</code>).
-Another way to see them is to double-click at a state in the chain, and the
-analysis tool will display the chain starting from that state.</p>
-</div>
-<div class="paragraph">
-<p>A situation that is not shown here, is that the analysis tool has no
-information about a state. It happens when the synthesis encountered a bad
-state on all paths to that state. In such a case, it displays that there is no
-information about the queried state.</p>

-<p>While this main simulation loop is simplified with respect to the real

-The simulator keeps taking transitions. Once a transition is taken, the current
-state is updated to the target state of the transition. This means that the
-other possible transitions (the ones that were not chosen), are not taken.
-Therefore, if we want to take a different transition, we should restart
-simulation from the initial state, and make different choices. That is, if we
-want to simulate a different trace, we perform another simulation.</p>

-<p>It should be clear by now, that simulating a single trace is almost never

-The other two options randomly choose a duration for the time transitions.
-For both options, a uniform random distribution is used, which is sampled to

-The upper bound (exclusive) of the uniform random distribution is to be
-provided by the user. You can think of these random options as adding an extra

-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton auto_time_trans_duration:
- const real UPPER = ...;

- disc real timeToWait;
- cont t der 1.0;
-
- location sampling:
- initial;
- edge do (timeToWait, d) := sample d goto waiting;
-
- location waiting:
- edge when t >= timeToWait do t := 0.0 goto sampling;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The upper bound of the uniform real distribution (<code>UPPER</code> > 0), is provided
-by the user. A sample is taken from the distribution, indicating the time to
-wait before the time transition is to be interrupted. Once that much time has
-elapsed, a new sample is taken, and the process repeats itself. The actual
-implementation is slightly different, in that no actual automaton is added,
-no additional <code>tau</code> transitions result from using this option, and no zero
-length time transitions are chosen. However, the effect is very similar.</p>
-</div>
-<div class="paragraph">
-<p>So, say the user wants to use a uniform distribution over interval [0 .. 10).
-The simulator takes a sample, say 3.0. Assume we then get a time transition for
-at most 0.5 time units. We take that entire transition and are left with 2.5
-remaining time units (3.0 - 0.5). If we then get another time transition for at
-most 1.2 time units, we take that one entirely as well. We are left with 1.3
-(2.5 - 1.2) time units. If we would then get a time transition for at most 5.0
-time units, the automatic input component ensures that we instead get a time
-transition for at most 1.3 time units, instead of one for at most 5.0 time
-units. Since we choose to interrupt after 1.3 time units anyway, there is no
-reason to compute the remainder of the time transition after those 1.3 time
-units. We choose the entire time transition of 1.3 time units, and compute a
-new sample. The simulator then once again calculates new transitions, and the
-process repeats. The next time transition that is calculated will be for the
-remaining 3.7 (5.0 - 1.3) time units, unless it is interrupted again before
-that time, i.e. if the new sample is smaller than 3.7.</p>

-<div class="paragraph">
-<p>The random durations are particularly useful in combination with
-<a href="#tools-cifsim-chapter-env-events">environment events</a>, as it allows the
-environment events to be chosen at the time the time transition is interrupted.
-That is, it allows the environment events to occur at random times.
-Using this option, the user can specify the distribution used for 'cutting up'
-the time transitions, and thus the possible moments when environment events can
-potentially take place. This is in addition to the state events, at which the
-environment events can also be chosen. These new additional possibilities
-however, are not influenced by the occurrence rate of the events of the system,
-and allow more control for the user. In particular for cases where the
-simulation allows infinite time transitions (no state events), the infinite

-used are mostly fixed, as the options don’t allow using for instance an
-exponential distribution. Furthermore, there is no way to specify the
-distribution for events individually, and it is not possible to specify the
-distribution between event transitions and time transitions. Concretely, the
-options for instance don’t enforce that environment events get chosen. They

-<div class="paragraph">
-<p>SVG input is usually combined with <a href="#tools-cifsim-output-chapter-realtime">real-time simulation</a>.
-Clicking an interactive SVG element results
-in the application of an input mapping, which results in an event. That event
-is put in the queue. If a time transition is being taken by the simulator, the
-simulator will continue to take that time transition until the input component
-interrupts it. However, an input component can only interrupt a time transition
-during <a href="#tools-cifsim-output-realtime-frames">intermediate frames</a>. As
-such, choosing a low <a href="#tools-cifsim-output-realtime-framerate">frame rate</a>
-(typically less than 10 frames per
-second) can significantly reduce the responsiveness of the SVG input.</p>

-<h8 id="tools-cifsim-input-svg-simulation-groups">Interactive groups</h8>
-<div class="paragraph">
-<p>It is possible to make a group of SVG elements (an <code>svg:g</code> element) an
-interactive element. By doing so, all the elements that are part of the group
-together become one single interactive element.</p>
-</div>
-<div class="paragraph">
-<p>One practical example where this is very useful, is for buttons with a text
-label. In SVG, this requires the use of a rectangle and a text label. To ensure
-that clicking either one of them results in the same event, group the rectangle
-and text label together in a group. Then assign an
-<a href="#tools-cifsim-output-svgviz-svg-id">id</a> to the group and use that id in
-an <a href="#tools-cifsim-input-svg-chapter-svgin">input mapping</a>. During simulation,
-when hovering over either the rectangle or the text label, both will will be
-highlighted. Clicking on either of them results in the corresponding input
-mapping being applied, and the resulting event being chosen by the SVG input
-component.</p>
-</div>
-<div class="paragraph">
-<p>In general, if an SVG image is clicked, the simulator will figure out on which
-graphical element the user clicked. If that element is itself an interactive
-SVG element, then the corresponding mapping is applied. If it is not an
-interactive SVG element, its parent (which may be a group) is checked. If the
-parent is not an interactive SVG element either, the parent of the parent is
-checked, etc. If none of the ancestors is an interactive SVG element, clicking
-the element has no effect on the simulation. Because of this behavior, it is
-strongly recommended not to make a child (or descendant in general) of an

-<h6 id="tools-supervisory-control-application-domain">Supervisory control application domain</h6>
-<div class="paragraph">
-<p>This section discusses environment events in the application domain of
-supervisory control, where the system consists of a plant (the hardware),
-and a supervisor (or other controller that restricts the plant behavior).</p>
-</div>
-<div class="paragraph">
-<p>Informally, we can distinguish the following types of events:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p><em>Controller events</em></p>
-<div class="paragraph">
-<p>Controller events are those events that are initiated by a controller, such
-as a supervisor. These events are usually controllable events. However, if
-supervisor synthesis is not used, the events need not necessarily be
-controllable.</p>
-</div>
-<div class="paragraph">
-<p>For controller events, the behavior is usually fully specified in the CIF
-model. That is, if the CIF model contains both the plant and the controller,
-the CIF model determines when the events are enabled, and when they are
-disabled. The controller events should happen as soon as they are enabled.
-That is, once the controller determines that for instance a motor should be
-turned on, the motor should be turned on without further delays. Thus,
-controller events are urgent.</p>
-</div>
-<div class="paragraph">
-<p>For low-level controllers, the events generally correspond directly to the
-events of the actuators. For instance, a controller may turn a lamp on or
-off. For higher level controllers however, there usually is no such direct
-relation. Furthermore, internal events of the controller (usually event
-<code>tau</code>, or other events that are neither controllable nor uncontrollable),
-are considered controller events as well.</p>
-</div>
-</li>
-<li>
-<p><em>Plant events</em></p>
-<div class="paragraph">
-<p>Plant events are those events that are initiated by the plants. These events
-are usually uncontrollable events. However, if supervisor synthesis is not
-used, the events need not necessarily be uncontrollable.</p>
-</div>
-<div class="paragraph">
-<p>For plant events, the behavior is usually fully specified in the CIF model.
-The CIF model models exactly when the events become enabled. For instance,
-when an elevator moves and reaches its top position, the event that indicates
-that 'the top position sensor goes on' becomes enabled, and should be
-executed at that time. That is, the plant model models/follows the physical
-behavior, and determines when the plants events are enabled. This behavior
-is fully specified and known, and further delays are undesirable. As such,
-plant events are urgent.</p>
-</div>
-<div class="paragraph">
-<p>For low-level plants, the events generally correspond directly to the events
-of sensors. Typical examples include limit sensors, such as the elevator top
-position sensor described above, and sensors that detect products throughout
-the system. For higher level plants however, there usually is no such
-direct relation. Furthermore, internal events of the plants (usually event
-<code>tau</code>, or other events that are neither controllable nor uncontrollable),
-may be considered plant events as well.</p>
-</div>
-</li>
-<li>
-<p><em>Environment events</em></p>
-<div class="paragraph">
-<p>Environment events are those events that are initiated by the environment
-(anything outside and the plants and the controller). These events are
-usually uncontrollable events. However, if supervisor synthesis is not used,
-the events need not necessarily be uncontrollable.</p>
-</div>
-<div class="paragraph">
-<p>The CIF model only observes or monitors the environment events. The
-environment (outside of the behavior specified in the CIF model), determines
-when, if ever, the events actually happen, and thus defines their behavior.
-From the point of view of the CIF model, the environment events can happen at
-any time, and as such the CIF model allows them at all times. The
-behavior is left completely unrestricted/free in the CIF specification, as
-it is unknown when the events will actually happen. Since time may pass
-before these events actually happen (as determined by the environment, rather
-than the CIF model), these events are thus non-urgent (from the point of view
-of the CIF model). If the CIF model would instead consider them to be urgent,
-the model would always forbid time to progress, even if the environment does
-not currently allow any environment event to occur, leading to deadlock.</p>
-</div>
-<div class="paragraph">
-<p>For low-level plants, the events generally correspond directly to the events
-of sensors. For instance, the buttons of a user interface can be pushed and
-released. Other typical examples of environment events include events for
-other user interface elements, and events that indicate that a product has
-entered the system, from the environment of the system. For higher level
-plants however, there usually is no such direct relation. Furthermore,
-internal events of the plants (usually event <code>tau</code>, or other events that
-are neither controllable nor uncontrollable), may be considered plant events
-as well.</p>
-</div>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>Thus, for plant events as well as for controller events, the CIF model
-specifies/defines when the events may/should occur, while for environment
-events the specification always allows them, and lets the environment
-choose/determine when they actually occur. In other words, plant/controller
-events originate from within the specification (internal behavior), while
-environment events originate outside of the specification (external behavior).</p>
-</div>
-<div class="paragraph">
-<p>A closed system is a system for which the entire behavior is specified in the
-CIF model. Closed systems have no environment events.</p>
-</div>
-<div class="paragraph">
-<p>An open system does not model the environment. As such, open systems typically
-have plant events, controller events, and environment events. The environment
-events are then unrestricted in the CIF model, leaving the environment (which
-is not specified) free to determine its own behavior, and thus the behavior
-(enabledness) of the environment events.</p>
-</div>
-<div class="paragraph">
-<p>An open system can be closed by adding a use case, which models one possible
-sequence of behavior of the environment, over time. That is, the added use case
-eliminates environment events, by defining when they are enabled. Open systems
-can also be closed by the simulator, as described above for the different
-input modes.</p>
-</div>
-<div class="paragraph">
-<p>As an example, consider the following open system:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">plant automaton Button:
- uncontrollable u_pushed, u_released;
-
- location Released:
- initial;
- edge u_pushed goto Pushed;
-
- location Pushed:
- edge u_released goto Released;
-end
-
-plant automaton Lamp:
- controllable c_on, c_off;
-
- location Off:
- initial;
- edge c_on goto On;
-
- location On:
- edge c_off goto Off;
-end
-
-supervisor automaton ButtonLampController:
- location:
- initial;
- edge Lamp.c_on when Button.Pushed;
- edge Lamp.c_off when Button.Released;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Here we have a simple button and a lamp. The lamp can only be turned on while
-the button is pushed, and will be turned off as soon as the button is released.
-The button events are environment events, since it always possible to either
-push the button, or release it.</p>
-</div>
-<div class="paragraph">
-<p>By specifying the button events as environment events, and specifying the the
-lamp events as <a href="#tools-cifsim-input-chapter-semi-automatic">semi-automatic</a>
-events, we can use the <a href="#tools-cifsim-input-chapter-console">interactive console input mode</a>
-or the <a href="#tools-cifsim-input-chapter-gui">interactive GUI input mode</a> to try different traces,
-where we only have to
-choose between the button events and how much time we want to let pass.</p>
-</div>
-<div class="paragraph">
-<p>Alternatively, we could add a use case, modeling one possible behavior of a
-user:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">plant automaton User:
- cont t der 1.0;
-
- location:
- initial;
- edge Button.u_pushed, Button.u_released when t >= 1 do t := 0.0;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This specifies that the user either pushes or releases the button, after one
-unit of time has passed (typically one second). Since clock <code>t</code> is reset each
-time, the user repeats this behavior. Thus, the button is pushed after one
-second, for one second, after three seconds, for one second, after five
-seconds, for one second, etc. This extended model (with use case), can be
-simulated using the <a href="#tools-cifsim-input-chapter-automatic">automatic input mode</a>, as the
-<code>User</code> plant automaton closes the system.</p>

-The CIF simulator supports several forms of
-<a href="#tools-cifsim-output-chapter-index">output</a>. By default, simulation results, such as the
-current <a href="#tools-cifsim-traces-state">state</a>, are printed to the console.
-While this provides useful information, it can also be useful to generate
-custom output, tailored to ones specific needs. To allow this, the CIF
-simulator supports <em>print output</em>.</p>
-</div>
-<div class="paragraph">
-<p>Simulation using the CIF simulator results in a
-<a href="#tools-cifsim-traces-traces">trace</a>. A trace consists of the
-<a href="#tools-cifsim-traces-state">states</a> that are encountered and the
-transitions that are taken, during the simulation. The print output
-declarations allow specifying for which transitions text should be printed
-(for instance only for transitions for a certain event), when the text should
-be printed (for instance before or after the transition), where the text should
-be printed (for instance to a file), and what text should be printed.</p>

-<p>Print output declarations are an extension to the CIF language, and can be
-specified directly in the CIF specification. They are only used to couple
-the model to textual output. They don’t influence the behavior of the model

-integration for the print output declarations extension, complete with syntax
-highlighting, background validation, etc.</p>

-<p>Consider the following CIF specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">print "Time=" + <string>time;</code></pre>
-</div>

-</div>
-</div>
-<div class="paragraph">
-<p>As you can see, due to rounding and simulation imprecision, the length of the
-textual representations of the values of <code>time</code> can vary wildly during
-simulation. Furthermore, the explicit casts (conversions) from real to string
-(<code><string></code>) and string concatenation (the <code>+</code> operator) can quickly
-become cluttered, and hard to read.</p>
-</div>
-<div class="paragraph">
-<p>To improve readability of the print declaration, we could adapt the CIF
-specification to the following:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">print fmt("Time=%s", time);</code></pre>
-</div>

-<div class="paragraph">
-<p>Here, manual text construction has been replaced by the use of the <code>fmt</code>
-standard library function. The first argument is a <em>format pattern</em>, and the
-remaining arguments are the values that are to be included in the text, in
-this case the value of variable <code>time</code>. The <code>fmt</code> function ensures that we
-no longer have to use casts. We also no longer have to create pieces of text
-and concatenate them (using the <code>+</code> operator).</p>
-</div>
-<div class="paragraph">
-<p>This is a typical use of a format pattern. The print declaration prints the
-value that results from text formatting. The value that is used is the value of
-variable <code>time</code>. The value of this variable is not used 'as is', but is
-instead converted to a textual representation using the format pattern. This
-format pattern specifies that the resulting text should start with <code>Time=</code>.
-It also specifies that the value (of variable <code>time</code>) should be included at
-the end of the textual representation. The <code>%s</code> part of the format pattern is
-a <em>format specifier</em>. The <code>%s</code> specifier is the generic specifier that can
-convert any type of value to a textual representation.</p>

-<p>As we saw in the previous section, due to rounding and simulation imprecision,
-the length of the generic textual representations of the values of variable

-alternative CIF specification:</p>

-specifies the precision, and indicates that the floating point number in
-decimal notation should have exactly two digits after the decimal point. When

-<code>%.2f</code> includes the value of variable <code>x</code>, the second <code>%.2f</code> includes the
-value of variable <code>y</code>, etc). The format pattern includes spaces between the
-format specifiers (between the <code>%.2f</code> parts), and thus the formatted values
-include spaces between them as well. When simulated, this could give the
-following output:</p>
-</div>
-<div class="listingblock">

-<p>Due to some larger values being mixed with shorter values, as well as due to

-<div class="paragraph">
-<p>Unlike many programming languages that have print statements, CIF has print
-declarations. Print declarations are
-<a href="http://en.wikipedia.org/wiki/Declarative_programming">declarative</a>,
-rather than
-<a href="http://en.wikipedia.org/wiki/Imperative_programming">imperative</a>.
-Print
-declarations center on transitions. The following is a schematic overview of
-a transition:</p>

-<div class="imageblock">
-<div class="content">
-<img src="./tools/cifsim/output/print/transition.png" alt="transition">
-</div>
-</div>
-<div class="paragraph">
-<p>The transition is graphically depicted as an arrow, with a label. The label
-denotes the event that occurred, or <code>time</code> for time transitions. Every
-transition has a <em>pre</em> or <em>source</em> <a href="#tools-cifsim-traces-state">state</a>,
-and a <em>post</em> or <em>target</em> state. The states are graphically depicted as circles,
-with a name above them. These names are only used so that they can be referred
-to from the text.</p>
-</div>
-<div class="paragraph">
-<p>The figure thus contains the transition and its immediate environment (its
-source and target states). Print declarations allow specifying what, how, and
-when to print, for transitions. Since the transition is the central part, we

-<h8 id="tools-extended-trace">Extended trace</h8>
-<div class="paragraph">
-<p>Simulation using the CIF simulator results in a
-<a href="#tools-cifsim-traces-traces">trace</a>. A trace consists of the
-<a href="#tools-cifsim-traces-state">states</a> that are encountered and the
-transitions that are taken, during the simulation. For instance, consider the
-following CIF specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton buffer:
- event add, remove;
- disc int cnt = 5;
-
- location:
- initial;
- edge add when cnt < 10 do cnt := cnt + 1;
- edge remove when cnt > 0 do cnt := cnt - 1;
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The <code>buffer</code> initially contains five items (<code>cnt = 5</code>). As long as there
-is room in the buffer (<code>cnt < 10</code>), an item can be added (event <code>add</code>) to
-the buffer. As long as the buffer is not empty (<code>cnt > 0</code>), an item can be
-removed (event <code>remove</code>) from the buffer. The following is a potential
-simulation trace:</p>
-</div>
-<div class="imageblock">
-<div class="content">
-<img src="./tools/cifsim/output/print/trace_normal.png" alt="trace normal">
-</div>
-</div>
-<div class="paragraph">
-<p>In the initial state (S1), variable <code>cnt</code> has value <code>5</code>. An item is then
-added (transition for the event <code>add</code>), resulting in a new state (S2), where
-<code>cnt</code> has value <code>6</code>. After that, another item is added, leading to state
-S3, where <code>cnt</code> has value <code>7</code>. Finally, an item is removed by means of a
-transition for event <code>remove</code>, leading to state S4, where <code>cnt</code> has value
-<code>6</code> again.</p>
-</div>
-<div class="paragraph">
-<p>As can be seen in the figure, the initial state (S1) has no incoming
-transition. Furthermore, the last/final state (S4) has no outgoing
-transition. As we’ll see later, that poses some difficulties in applying the
-transition centric view. To get around these limitations, the trace is extended
-as follows:</p>
-</div>
-<div class="imageblock">
-<div class="content">
-<img src="./tools/cifsim/output/print/trace_extended.png" alt="trace extended">
-</div>
-</div>
-<div class="paragraph">
-<p>A transition with the <em>initial</em> label is added before the initial state, and a
-transition with the <em>final</em> label is added after the final state. This ensures
-that all states have an incoming and outgoing transition. These two added
-transitions are <em>virtual</em>, they don’t actually exist. They are added only for
-the benefit of print output. That is, they don’t affect the simulation behavior
-of the model, and are thus not part of the 'real' trace.</p>
-</div>
-<div class="paragraph">
-<p>The added 'initial' virtual transition has no source state, and the added
-'final' virtual transition has no target state. Since in the transition centric
-view every transition should have a source and a target state, we add the
-initial state (S1) as source state (S0) for the 'initial' transition, and the
-final state (S4) as target state (S5) for the 'final' transition. This way,
-every transition (whether virtual or real) has a source and target state, and
-fits the transition centric view. For the 'initial' and 'final' virtual
-transitions, the source and target states are thus the same (S0 = S1, S4 = S5).</p>
-</div>
-<div class="paragraph">
-<p>The trace with added virtual 'initial' and 'final' transitions, and with the

-<h8 id="tools-specifying-the-text-to-print">Specifying the text to print</h8>
-<div class="paragraph">
-<p>Every print declaration must specify <em>what</em> to print, using CIF expressions.
-These CIF expressions can for instance refer to variables from the CIF model.
-Since variables can change values, it is important to know in which state the
-expression is evaluated. In the transition centric view, we have two states to
-choose from, the pre/source state and the post/target state. The following
-variants are supported to specify what to print:</p>

-</div>
-</div>
-<div class="paragraph">
-<p>The first variant has only one expression, which is printed in the post/target
-state. The third variant is identical, but explicitly indicates that the
-post/target state is used. The second variant also has a single expression, but
-is evaluated in the pre/source state. The fourth variant has two expression,
-one of which is evaluated in the pre/source state, and one of which is
-evaluated in the post/target state. The first three variants only print one
-piece of text per transition, while the fourth variant prints two pieces of
-text per transition.</p>

-<p>The expressions that indicate what text to print may be of any type, and the

-that closely resembles the textual syntax of CIF. For string literals this
-means that the text is escaped, and double quotes are added. If however the
-result of the expression is a <code>string</code> typed value, then that string is used
-'as is' (without quoting, and without escaping). Thus, consider the following
-example:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">print ["a\"b"];
-print "a\"b";</code></pre>

-<div class="paragraph">
-<p>The first print declaration prints a list that contains a single string value,

-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">["a\"b"]

-<p>That is, in general string values are quoted and escaped, as is the case for

-evaluated in the post/target state of the transition results in value <code>true</code>,
-text may be printed. Otherwise, no text is printed for that transition.</p>
-</div>
-<div class="paragraph">
-<p>The second variant also has a single predicate, but is evaluated in the

-is only printed if the pre/source state satisfies the first predicate, and the
-post/target state satisfies the second predicate. If either of the states does
-not satisfy its corresponding predicate, no text is printed for that
-transition.</p>

-</div>
-<div class="paragraph">
-<p>The first example prints <code>a</code> after each transition, and does not restrict the
-pre/source or post/target states. The second example only prints <code>b</code> for

-<p>For the first example, the value of variable <code>time</code> is printed after time

-value of variable <code>x</code> is strictly less than three, and after such transitions
-the value of variable <code>x</code> is strictly larger than <code>5</code>. For the third
-example, the value of variable <code>y</code> is printed twice for all 'default'

-<div class="paragraph">
-<p>The <code>fmt</code> function requires at least one argument, the <em>format pattern</em>. The
-remaining arguments of the function are the <em>values</em> that can be inserted into
-the format pattern, to allow variable output. For instance, consider:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">fmt("%s %s", x, y)</code></pre>
-</div>

-<p>Here, <code>"%s %s"</code> is the format pattern, <code>x</code> is the first value, and <code>y</code> is
-the second value.</p>
-</div>
-<div class="paragraph">
-<p>The first argument, the format pattern, must be a string literal. That is, it
-must be text between double quotes (<code>"</code>).</p>
-</div>
-<div class="paragraph">
-<p>The real usefulness of format patterns comes from the inclusion of the values
-into the format pattern. The values can be included by inserting format
-specifiers (e.g. <code>%s</code>) into the format pattern. Multiple values may be used
-by including multiple format specifiers. The first format specifier includes
-the first value, the second format specifier includes the second value, etc.</p>
-</div>
-<div class="paragraph">
-<p>The result of <code>fmt</code> applied to it arguments is the text of the format
-pattern, with the format specifiers replaced by their corresponding values.</p>
-</div>

-<p>Format specifiers can be customized to influence how their corresponding values
-are to be inserted. For instance, consider:</p>

-</div>
-<div class="paragraph">
-<p>They are optionally followed by a value index. If the value index is specified,
-it must be followed by a dollar sign (<code>$</code>). The value index is a positive
-decimal integer indicating the position of the value in the value list. The
-first value is referenced by <code>1$</code>, the second by <code>2$</code>, etc. Index zero and
-indices starting with zero are not allowed.</p>
-</div>
-<div class="paragraph">
-<p>The index is followed by optional flags. Flags are characters that modify the
-output, and may be specified in any order. Each flag may only be specified once
-per specifier. The set of valid flags depends on the conversion.</p>
-</div>
-<div class="paragraph">
-<p>After the flags, an optional width may be specified. The width is a
-non-negative decimal integer indicating the minimum number of characters that
-should be included in the result, for that specific specifier.</p>
-</div>
-<div class="paragraph">
-<p>After the width, a precision may optionally be specified. A precision is always
-preceded by a dot (<code>.</code>). The precision is a non-negative decimal integer used
-to restrict the number of characters. The specific behavior depends on the

-(<code>%3$f</code>) explicitly specifies index <code>3</code> and thus uses the third value. The
-fourth specifier (<code>%d</code>) is the second specifier to not explicitly specify an

-is the third specifier to not explicitly specify an index, and thus implicitly

-
-The SVG visualization feature uses Scalable Vector Graphics (SVG) images.
-<a href="http://www.w3.org/TR/SVG11/">SVG</a>
-is a widely-deployed royalty-free standard
-for two-dimensional vector graphics, developed by the
-<a href="http://www.w3.org/">World Wide Web Consortium</a>
-(W3C). SVG images consist of
-three types of objects: vector graphic shapes (rectangles, circles, etc.),
-raster images, and text. The benefit of vector images formats over raster image
-formats, is that raster images are created with a fixed size, while vector
-images contain a description of the image and can be rendered at any size
-without loss of quality.</p>
-</div>
-<div class="paragraph">
-<p></p>
-</div>
-<div id="tools-cifsim-output-svgviz-svg-svg11" class="paragraph">
-<p>Multiple versions of the SVG standard exist. The CIF simulator uses the
-free and open source
-<a href="http://xmlgraphics.apache.org/batik/">Apache Batik SVG Toolkit</a>
-to render SVG images. Batik supports
-version 1.1 of the SVG specification.</p>
-</div>
-<div class="paragraph">
-<p>
-SVG image files are stored in an
-<a href="http://en.wikipedia.org/wiki/XML">XML</a>-based file format. This means that
-they can be edited with any text editor. However, it is often more convenient
-to edit them with a drawing program that supports vector graphics, such as
-<a href="http://www.adobe.com/products/illustrator.html">Adobe Illustrator</a>
-or
-<a href="#tools-cifsim-output-svgviz-chapter-inkscape">Inkscape</a>. Most modern web
-browsers also support SVG images.</p>
-</div>
-<div class="paragraph">
-<p>Since SVG images are essentially XML files, we get all the benefits of XML
-for free. One of those benefits is that XML files represent tree structures,
-which can be easily manipulated by applications. This is essential for the CIF
-simulator. During initialization, the CIF simulator loads the SVG image
-file that the user provided, and subsequently has access to the XML tree.
-It then uses the aforementioned Batik toolkit to draw the SVG image
-represented by the XML tree. Once the simulator starts taking transitions and
-updates its <a href="#tools-cifsim-traces-state">state</a>, it can use the
-information from the state to modify the XML tree. Changes to the XML tree then
-result in an updated SVG image, the next time the image is rendered again.</p>

-</div>
-<div id="tools-cifsim-output-svgviz-svg-id" class="paragraph">
-<p>In order to be able to modify particular objects (shapes, text labels, etc.) of
-the SVG image, the simulator should be able to identify the objects that make
-up the image. Here we once again reap the benefits of XML. All nodes (called
-elements) in the XML tree can have an <code>id</code> attribute that specifies the
-id (also called name or identity) of the element. As such, all SVG objects can
-be identified using their unique id. The
-<a href="#tools-cifsim-output-svgviz-svgout-id">SVG element id</a> section of the

-<div class="paragraph">
-<p>The <code>svgout</code> keyword is followed by a specification of an SVG element
-<a href="#tools-cifsim-output-svgviz-svg-id">id</a>. Every output mapping must
-<a href="#tools-cifsim-output-svgviz-svgout-id">specify the id</a> of an SVG
-element, and an SVG element with that id must exist in the SVG image. The
-<code>id</code> indicates the element for which an attribute or text is to be updated.</p>
-</div>
-<div class="paragraph">
-<p>The <code>id</code> is followed by a specification of what part of the SVG element is to

-The id is checked, to make sure an SVG element with that id actually exists in
-the SVG image.</p>
-</div>
-<div class="paragraph">
-<p>Only valid SVG names may be used as ids. Valid SVG names start with a letter
-(<code>a</code> to <code>z</code>, <code>A</code> to <code>Z</code>), an underscore (<code>_</code>), or a colon (<code>:</code>),
-and may be followed by more of the same characters, as well as dashes (<code>-</code>),
-dots (<code>.</code>), and numbers (<code>0</code> to <code>9</code>).</p>
-</div>
-<div class="paragraph">
-<p>Ids must be put between double quotes. For instance, to use <code>some-name</code> as
-id, it must be written as <code>"some-name"</code>.</p>
-</div>
-<div class="paragraph">
-<p>Instead of using a hard coded SVG element id, it is also allowed to use an
-expression that when evaluated results in the SVG element id. Such an
-expression must evaluate to a <code>string</code> typed value, and must be statically
-evaluable (must not refer to variables that can change value during simulation,
-etc). For instance:</p>
-</div>
-<div class="listingblock">

-const string c = "bo";
-svgout id c + "x" attr "width" value ...;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The first output mapping applies to the SVG element with the id <code>box</code>. The
-<code>box</code> id is hard coded into the output mapping. The second
-output mapping uses the expression <code>c + "x"</code> to specify the SVG element id.
-Once the expression is evaluated (its value is computed), this results in the
-<code>string</code> typed value <code>"box"</code>. As such, the second mapping applies to the
-SVG element with id <code>box</code> as well.</p>
-</div>
-<div class="paragraph">
-<p>The expressions may also refer to for instance algebraic parameters of
-automaton definitions. Since different values can be given to the parameters
-for each instantiation, this allows the SVG element id to vary for the
-different instantiations of the automaton definition. This particular usage
-allows for reuse and scalable solutions. The

-<a href="#tools-cifsim-output-svgviz-chapter-example-workstation">workstation example</a>

-Similarly to specifying ids, attribute names must be valid SVG names. They also

-attribute (in any casing) using an output mapping is explicitly not supported,
-to avoid conflicting style changes. See also the

-</div>
-<div class="paragraph">
-<p>The supported attributes for an SVG element depend on what kind of element it

-<p>Rectangle <code>rect1</code> uses the SVG presentation attribute <code>fill</code> to specify the

-<code>fill</code> to specify the fill color the rectangle. The SVG presentation
-attributes are all direct attributes of the SVG element. CSS style attributes
-on the other hand, are always part of the SVG presentation attribute <code>style</code>.</p>
-</div>
-<div class="paragraph">
-<p><a href="https://en.wikipedia.org/wiki/Cascading_Style_Sheets">CSS</a>
-stands for
-<em>Cascading Style Sheets</em>, and it is a style sheet language used
-for describing the look and formatting of a document. It’s best known for its
-use in styling web pages written in
-<a href="https://en.wikipedia.org/wiki/HTML">HTML</a>.
-Like SVG, CSS is an international
-standard developed and maintained by the
-<a href="http://www.w3.org/">World Wide Web Consortium</a>
-(W3C). SVG reuses the CSS standard for its CSS style
-attributes. The most commonly used attributes for certain elements are also
-available in the SVG standard as SVG presentation attributes. Furthermore, SVG
-adds additional presentation attributes not found in CSS.</p>
-</div>
-<div class="paragraph">
-<p>If an attribute is specified on an element using both an SVG presentation
-attribute, and a CSS style attribute, the CSS style attribute usually takes
-precedence. The output mappings handle all of this automatically and
-transparently. That is, you just specify the attribute name in the header of
-the output mapping, and the simulator makes sure the proper attribute is
-update, regardless of whether it is an SVG presentation attribute, or a CSS
-style attribute. It is explicitly not supported to change the <code>style</code>
-attribute directly (using an output mapping), in order to avoid conflicting
-style changes when other output mappings update CSS style attributes that are

-<div class="paragraph">
-<p>In order for an output mapping to be able to update attributes or text labels,

-<a href="#tools-cifsim-output-svgviz-svgout-simple">simple output mapping</a> example
-already showed how
-a value can be specified. This section further explains the details of the
-specification of such values.</p>
-</div>
-<div class="paragraph">
-<p>The <code>value</code> keyword is followed by an expression. This expression may
-for instance be a literal value, such as <code>1</code>, <code>true</code>, <code>1.0</code>,
-<code>"some text"</code>, or <code>[1, 2]</code>. At first, it might not seem useful to use a
-literal as a value for an output mapping, since the mapping will then produce
-the same value every time it is applied. However, the
-<a href="#tools-cifsim-output-svgviz-chapter-example-rate">rate example</a> shows why this can in fact be
-very useful.</p>
-</div>
-<div class="paragraph">
-<p>The expressions however, may also contain references to variables (discrete,
-continuous, or algebraic), functions, constants, locations, etc. For instance,
-we could use the value of a continuous variable and multiply it by two, by
-using <code>x * 2</code> as expression, assuming that the continuous variable is named
-<code>x</code>. Since we may refer to the <a href="#tools-cifsim-traces-state">state</a> of
-the CIF specification, the value of the expression can change as the simulation
-continues, resulting in different values being mapped to the image.</p>
-</div>
-<div class="paragraph">
-<p>The expressions can also include <code>if</code> expressions, which are particularly
-powerful in this context. Using <code>if</code> expressions, a different value can be
-used for several different conditions. See the

-<div class="paragraph">
-<p>The value expression of an output mapping may be of any type. The result of
-evaluating the expression is converted to a textual representation that closely
-resembles the textual syntax of CIF, before using it to set the value of an
-attribute, or the text of a text label. For string literals this means that the
-text is escaped, and double quotes are added. If however the result of the
-expression is a <code>string</code> typed value, then that string is used 'as is'
-(without quoting, and without escaping). Thus, consider the following examples:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">svgout id "..." attr "..." value ["a\"b"];
-svgout id "..." attr "..." value "a\"b";</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The value of the first output mapping is a list that contains a single string
-value, while the value of the second output mapping is a string value directly.
-This results in the following texts being used as values of the attributes:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">["a\"b"]
-a"b</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>That is, in general string values are quoted and escaped, as is the case for

-'as is', without quoting and without escaping.</p>

-<div class="sect7">
-<h8 id="tools-cifsim-output-svgviz-svgout-whitespace">Whitespace handling</h8>

-<p>If the textual result of an output mapping contains a new line character (for
-instance due to including <code>\n</code> in a string literal or
-<a href="#tools-cifsim-output-print-ref-fmt-pattern">format pattern</a>), the new
-line character is ignored by SVG. Furthermore, tabs (<code>\t</code>) are replaced by a
-single space character. Finally,
-<a href="http://www.w3.org/TR/SVG/text.html#WhiteSpace">by default</a>
-consecutive
-spaces (including tabs) are merged together into a single space, and spaces at
-the beginning and end of the output of a mapping are discarded by SVG.</p>
-</div>

-<p>This essentially renders <code>\n</code> and <code>\t</code> useless, as the first is ignored,
-and for the second spaces can be used instead.</p>
-</div>
-<div class="paragraph">
-<p>This also means that it is not possible to set multiple lines of text using a
-single output mapping. This is a fundamental restriction of SVG, not of CIF/SVG

-for each <code>tspan</code> element. The benefit over multiple text labels (multiple
-<code>text</code> elements with a single <code>tspan</code> child element each) is that the one

-</div>
-</div>
-<div class="paragraph">
-<p>The <code>svgcopy</code> keyword is followed by a specification of an SVG element
-<a href="#tools-cifsim-output-svgviz-svg-id">id</a>. Every copy declaration must
-<a href="#tools-cifsim-output-svgviz-svgout-id">specify the id</a> of an SVG
-element, and an SVG element with that id must exist in the original SVG image,
-or must exist after applying one of the other copy declarations of the same
-CIF specification. The <code>id</code> indicates the element that is to be copied.</p>
-</div>
-<div class="paragraph">
-<p>The prefix and postfix are both optional, but at least one of them must be
-specified. The prefix and postfix are used to generate unique ids for the
-copied elements. The prefix (if any) is prepended to the ids of the copied
-elements, while the postfix (if any) is appended to the ids of the copied
-elements. Prefixes (if specified) must be valid SVG name prefixes, which means
-they must be valid SVG names, just as
-<a href="#tools-cifsim-output-svgviz-svgout-id">SVG element ids</a>.
-Similarly, postfixes (if specified) must be valid SVG name postfixes, which
-means they must be valid SVG names, but may start with dashes (<code>-</code>), dots
-(<code>.</code>), and numbers (<code>0</code> to <code>9</code>). Similar to
-<a href="#tools-cifsim-output-svgviz-svgout-id">ids</a>, expressions may be
-used for both prefixes and postfixes, as long as they result in a <code>string</code>
-typed value when they’re evaluated.</p>
-</div>
-<div class="paragraph">
-<p>If we look at the rectangles example above, we see that the <code>rect</code> element is
-copied, and that the <code>id</code> of the copied element is prefixed with <code>a</code>,
-resulting in <code>arect</code> as <code>id</code> of the copy. Similarly, <code>rect3</code> is prefixed
-with <code>_</code> and postfixed with <code>x</code> resulting in <code>_rect3x</code> as <code>id</code> of the
-copy.</p>
-</div>
-<div class="paragraph">
-<p>The <code>grp</code> element is copied as well, with a <code>b</code> postfix. This results in
-a copied group with <code>grpb</code> as its <code>id</code>. Group <code>grp</code> also contains the
-rectangle with id <code>rect2</code>. When an element is copied, all its contents are
-copied as well. That is, the copy is recursive. This means that the <code>rect2</code>
-element is copied as well, and that copy is also given a <code>b</code> postfix,
-resulting in <code>rect2b</code> as its <code>id</code>.</p>
-</div>
-<div class="paragraph">
-<p>In the syntax examples above, we see that it is also allowed to declare a

-<p>The copies are added to the SVG image, as siblings of their originals. That is,
-the copies are added just before their originals. In the rectangles example
-above, this means that the <code>arect</code> copy is added just before the <code>rect</code>
-original, and the <code>grpb</code> copy is added just before the <code>grp</code> original.</p>
-</div>
-<div class="paragraph">
-<p>The order of the <code>rect</code>, <code>rect2</code>, and <code>rect3</code> rectangles is important,
-in that it determines their <em>rendering order</em>. Elements that are listed first,
-get <em>rendered</em> or <em>painted</em> first. Subsequent elements are painted on top of
-previously painted elements. Thus, the red <code>rect</code> rectangle is painted first,
-and is partially covered by the green <code>rect2</code> rectangle, which is painted
-second and is partially covered by the blue <code>rect3</code> rectangle, which is
-painted third.</p>

-<h8 id="tools-cifsim-output-svgviz-simulation-order">Application order</h8>
-<div class="paragraph">
-<p>When the simulator is started, the SVG image is loaded. First, the
-<a href="#tools-cifsim-output-svgviz-chapter-svgcopy">CIF/SVG copy declarations</a> are
-applied, to ensure all elements exist. For copies of copied elements, the
-former are applied after the latter, to ensure the elements that need to be
-copied actually exist. Besides that, the copy declarations from a CIF file
-are applied in the order in which they are specified (after
-<a href="#tools-cif2cif-chapter-elim-comp-def-inst">elimination of component definition/instantiation</a>).
-The copy declarations are only applied once.</p>
-</div>
-<div class="paragraph">
-<p>After the copy declarations, the
-<a href="#tools-cifsim-output-svgviz-chapter-svgmove">CIF/SVG move declarations</a>
-are applied. The move declarations from a CIF file are applied in the order in
-which they are specified (after
-<a href="#tools-cif2cif-chapter-elim-comp-def-inst">elimination of component definition/instantiation</a>).
-The move declarations are only applied once.</p>
-</div>
-<div class="paragraph">
-<p>The <a href="#tools-cifsim-output-svgviz-chapter-svgout">CIF/SVG output mappings</a> are
-applied after that, for the initial <a href="#tools-cifsim-traces-state">state</a>.
-After the output mappings have been applied, the resulting SVG image is shown
-by the simulator. The output mappings are applied again and again, as the state
-of the CIF model changes.</p>
-</div>
-<div class="paragraph">
-<p>The output mappings from a CIF file are applied in the order in
-which they are specified (after
-<a href="#tools-cif2cif-chapter-elim-comp-def-inst">elimination of component definition/instantiation</a>).
-Note however, that the order does not matter, as all output mappings are
-<a href="#tools-cifsim-output-svgviz-svgout-unique">unique</a> and independent of each
-other.</p>
-</div>
-<div class="paragraph">
-<p>Each mapping that is applied, results in an update of an attribute or text
-label. Either the new value is different from the previous value, or the value
-is updated to the value that was already there. The results of the mappings
-are cumulative. That is, the first mapping is applied to the original SVG
-image, the second mapping is applied to the image that resulted from applying
-the first mapping, the third mapping is applied to the image that resulted
-from applying the second mapping, etc.</p>
-</div>
-<div class="paragraph">
-<p>During simulation, the simulator provides states to the SVG visualizer, which
-applies the mappings to each of those states, in order to generate
-<a href="#tools-cifsim-output-realtime-frames">frames</a>. Whenever the
-mappings are applied, they are all applied, one after the other. Between the
-application of the individual output mappings, the display is never updated.
-That is, only after all mappings are applied, is the visualization updated.
-This assures that the images are in a consistent state when they are rendered.</p>
-</div>
-<div class="paragraph">
-<p>By changing the <code>width</code> and <code>height</code> attributes of the root <code>svg</code> element
-of an SVG image, it is possible to change the size of the image, and thus the
-canvas on which it is displayed during simulation. Changes to these attributes
-currently only have effect for the initial state. If the size of the image is
-changed during simulation, such changes are ignored.</p>

-<div class="sect7">
-<h8 id="tools-cifsim-output-svgviz-debugging-console">Console debugging</h8>
-<div class="paragraph">
-<p>Console debugging for CIF/SVG declarations can be enabled or disabled by using
-the
-<b class="menuref">Debug output</b>
-option (<b class="menuref">Output</b>
-category). It is
-disabled by default. If enabled, it produces debug output to the console,
-whenever CIF/SVG declarations are applied. Here is an example of what such
-output looks like:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">SVG output ("some_file.svg") id "a" text: "10.00"

-SVG output ("some_file.svg") id "c" text: "3.16"
-SVG output ("some_file.svg") id "n" attr "fill" (CSS attr): "#ff0000"

-</div>
-</div>
-<div class="paragraph">
-<p>Each of the output mappings that is applied, results in a line of debugging
-output. For output mappings that update the value of an attribute, the output
-indicates whether the attribute is handled as an
-<a href="#tools-cifsim-output-svgviz-svgout-svgcss">SVG presentation attribute</a> or as a
-<a href="#tools-cifsim-output-svgviz-svgout-svgcss">CSS style attribute</a>.</p>

-<p>The textual representations of the values that are set, are put between double
-quotes, and their content is not escaped in any way.</p>
-</div>
-<div class="paragraph">
-<p>
-Due to the asynchronous nature of the SVG visualizer, the simulator will
-continue to calculate the next states that are to become a frame, while the SVG
-visualizer is still applying mappings for previous frames. As such, the debug
-output and other simulation output are likely to be out of sync and
-interleaved. To ease debugging, you can enable the
-<a href="#tools-cifsim-chapter-test-mode">test mode option</a>, which ensures synchronous
-execution, and thus synchronous output.</p>
-</div>
-<div class="paragraph">
-<p>For the input mappings, whenever an interactive SVG element is clicked, and
-the corresponding mapping is used to determine the event to take, a line of
-debug output is produced. Here is an example of what such output looks like:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">SVG input ("some_file.svg") id "button": event "button.u_pushed"

-<code>button</code> was clicked, and this resulted in the execution of event
-<code>button.u_pushed</code>.</p>

-using the
-<b class="menuref">Group</b>
-command from Inkscape’s
-<b class="menuref">Object</b>
-menu.
-The group can also be seen in the XML representation, as an <code>svg:g</code> element,
-with the actual shapes (paths in this case) as children. We assigned the
-<code>person</code> id to the <code>svg:g</code> element, as it represents the entire person. For

-<p>Note that we moved the person as a whole, to the start of the floor. Since
-<code>svg:g</code> elements don’t have an <code>x</code> and <code>y</code> attribute in SVG, Inkscape
-applies a translation to move the group. This is reflected in the XML as a
-<code>transform</code> attribute, with the <code>translate(-290,-467)</code> value. This
-indicates that the person was moved 290 pixels to the left, and 467 pixels to
-the top (as SVG has its origin in the upper left corner of the canvas).</p>

-<p>To get rid of this, once the person is at the correct initial position, we
-can ungroup the <code>person</code> group (

-transformation is pushed to the individual elements of the group. The regroup
-simply adds a new group around the elements, without a translation
-transformation. The new group is given an automatically generated name, so we
-need to rename it to <code>person</code>. This ungroup/group trick is often very useful.

-<p>The example models a workstation with two machines. The first machine has a
-processing time of <code>1.0</code> time units and the second machine has a processing
-time of <code>2.5</code> time units. Each machine gets products to <code>start</code> processing,
-processes them, and sends them out as it is <code>done</code>. The first machine gets
-its input from an infinite generator (event <code>generate</code>). The second machine
-sends its finished products to an infinite exit buffer (event <code>exit</code>).
-Products are transported from the first machine to the second machine via a
-transport system (event <code>transfer</code>). Note that the <code>Machine</code> automaton
-definition has three locations. In location <code>idle</code> it is waiting for a
-product to enter the machine (event <code>start</code>). In location <code>processing</code> it
-processes the product, which takes <code>ptime</code> time units. Finally, in location
-<code>completed</code> it has completed processing the product, and waits until it can
-send it as output. After that, the machine is back in the <code>idle</code> location,
-where it waits for the next product.</p>
-</div>
-<div class="paragraph">
-<p>Both machines (<code>m1</code> and <code>m2</code>) are instantiations of the same automaton
-definition (<code>Machine</code>). The definition/instantiation mechanism allows us to
-specify the behavior of a machine only once, and still have multiple machines.
-This reuse improves scalability, as well as maintainability. The reuse of the
-behavior applies to the visualization as well. By declaring the output mappings
-in the automaton definition, we get mappings for each instantiation of an
-actual machine.</p>
-</div>
-<div class="paragraph">
-<p>Since each machine has its own graphical representation in the SVG image, the
-graphical elements for the different machines have different ids as well.
-However, they only differ in the number that is used. For instance, there is
-an <code>m1_bar_front</code> rectangle for the first machine, and an <code>m2_bar_front</code>
-rectangle for the second machine. In order to make sure each machine gets the
-correct mappings that apply to their own ids, we added an algebraic parameter
-<code>nr</code> to the definition of <code>Machine</code>, that indicates to the machine which
-machine it is. We can then use that <code>nr</code> to compute the id. For machine
-<code>m1</code>, the <code>Machine</code> automaton definition is instantiated with value <code>1</code>
-for the <code>nr</code> parameter. The <code>"m" + <string>nr + "_bar_front"</code> id expression
-then evaluates to <code>"m1_bar_front"</code>, and <code>m1_bar_front</code> is used as the id
-for the output mapping.</p>
-</div>
-<div class="paragraph">
-<p>The first mapping updates the width of the <code>m*_bar_front</code> rectangles to show
-the progress of the machines. If a machine is actually <code>processing</code>, the
-value of clock <code>t</code> is used, as that clock indicates how much of the
-processing has been completed.</p>
-</div>
-<div class="paragraph">
-<p>When a machine is <code>idle</code> (and waiting for a product) or has <code>completed</code>
-processing (but can not yet push the processed product out of the machine),
-the progress is either nothing, or everything. In both cases, we choose the
-full processing time (variable <code>ptime</code>) as the value. The reason to choose
-this value for the <code>idle</code> location, becomes clear in the next output mapping.</p>
-</div>
-<div class="paragraph">
-<p>The <code>ptime</code> value is chosen for the <code>completed</code> location to ensure that
-the rectangle does not get wider than the box (rectangle <code>m*_bar_back</code>). If
-we would have used the value of clock <code>t</code> in this location as well, then
-since the value of the clock keeps increasing in that location, the value
-becomes larger than <code>ptime</code>, and thus the progress bar would be partly
-outside the box (rectangle <code>m*_bar_back</code>).</p>
-</div>
-<div class="paragraph">
-<p>The value that is selected for this first mapping, is transformed using the
-<code>scale</code> standard library function. The function is used to scale the
-processing time interval [0 .. <code>ptime</code>] to the [0 .. 130] interval, which
-represents the <code>width</code> of the rectangle in pixels. The upper bound of 130
-pixels matches the <code>width</code> of the box (rectangle <code>m*_bar_back</code>).</p>
-</div>
-<div class="paragraph">
-<p>The second mapping updates the <code>fill</code> color (foreground color) of the same
-SVG element. In the <code>idle</code> location, the color is <code>gray</code>. Since we used the
-full width in that location (value <code>ptime</code> in the [0 .. <code>ptime</code>] interval),
-the entire box is then filled by a gray rectangle, indicating that the machine
-is idle.</p>
-</div>
-<div class="paragraph">
-<p>For the other locations, the <code>fill</code> color is set to <code>dodgerblue</code>. Since the
-width in pixels is a value in the interval [0 .. 30], part of the box will be
-blue, and part will be the background color of the box, which is white. In the
-<code>completed</code> location, the full width is used as well, resulting in a
-completely blue box, indicating that the machine has a completely processed
-product, waiting to be released as output.</p>

-<p>This SVG image is the same as the original SVG image for this example, but with
-an inverted <code>y</code>-axis, for the <code>water</code> rectangle. The <code>y</code>-axis was
-inverted by using the
-<b class="menuref">Flip Vertical</b>
-command from Inkscape’s
-<b class="menuref">Object</b>
-menu, while the <code>water</code> rectangle was selected. As can be
-seen in the screenshot, Inkscape corrects for the applied transformation, and
-still indicates the same <code>x</code> and <code>y</code> coordinates (at the top of the
-screenshot). In SVG (and thus the
-<b class="menuref">XML Editor</b>
-window), we see a new
-<code>transform</code> attribute, <code>scale(1,-1)</code> as value, which represents the
-inversion of the <code>y</code>-axis. Also, the bottom of the water (the inverted top of
-the water) is now <code>90</code> pixels (the inverted <code>-90</code> value of the <code>y</code>
-attribute) from the top of the image. Using this vertical flip, we now fixated
-the 'bottom' of the water, and we can thus change the height of the water
-without having to correct its position. The mappings for this modified SVG

-<p>This specification has two lamps, <code>lamp1</code> and <code>lamp2</code>. Both lamps have
-identical behavior, and therefore the behavior is only specified once, using
-automaton definition <code>Lamp</code>. This definition is instantiated two times, once
-for each of the lamps. A lamp is initially off, can go on, go off again, go on
-again, etc. The following SVG image is used for this example:</p>

-lamp that is off has a thin border and the lamp that is on has a thicker
-border. The CIF specification also contains four

-<p>The use of the automaton definition allows us to add another lamp by simply

-<pre class="CodeRay highlight"><code data-lang="cif">lamp3: Lamp();</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This single line ensures that we have a third lamp, with the corresponding
-behavior. However, we also need to adapt the SVG image, by adding another
-circle, and we need to add two more output mappings to the CIF model. In this
-case, the additional amount of work is manageable. If however our lamp would
-have been represented in the image by many different graphical elements,
-adding another lamp would require copying all those graphical elements, and
-might also lead to adding many more output mappings per lamp.</p>
-</div>
-<div class="paragraph">
-<p>Furthermore, if we were to decide to change the graphical representation of
-lamps from a circle to a square, we would have to change the graphical
-representation of each of the lamps in the image.</p>
-</div>
-<div class="paragraph">
-<p>It should be clear that this approach does not scale very well. Ideally, we
-would add another lamp by just adding another instantiation of the <code>Lamp</code>
-definition as we did above, and automatically get another circle in the image,
-and two more output mappings in the CIF model.</p>

-</div>
-<div class="sect7">
-<h8 id="tools-a-scalable-solution">A scalable solution</h8>
-<div class="paragraph">
-<p>For the behavior of the lamp, we already had a scalable solution, by using the
-component definition/instantiation mechanism. That same mechanism can be used
-to make the image and mappings scalable. First, we’ll change the SVG image:</p>
-</div>
-<div class="imageblock">
-<div class="content">
-<img src="./tools/cifsim/output/svgviz/lamps/lamps3_inkscape.png" alt="lamps3 inkscape">
-</div>
-</div>
-<div class="paragraph">
-<p>The second lamp has been removed from the image. We only keep one lamp, as a
-sort of template for all the lamps. Since we want to use the same graphical
-representation for all lamps, we only want to include it once in the SVG image.
-This allows us to change the graphical representation of the template, to have
-all the lamps change appearance at once. The lamp has been moved outside of the
-visible part of the canvas, and its <code>id</code> has been changed from <code>lamp1</code> to
-<code>lamp</code>. The reason for these last two changes will become clear once we look
-at the new CIF model, and especially the new output mappings:</p>
-</div>
-<div class="listingblock">

-end
-
-lamp1: Lamp(1);
-lamp2: Lamp(2);
-lamp3: Lamp(3);</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The first change is that the <code>Lamp</code> automaton definition now has a <code>nr</code>
-parameter, that indicates which lamp it is. Each lamp is given a different
-number when instantiated. This allows the lamp automata to know their own
-identity, and use that for the SVG visualization.</p>
-</div>
-<div class="paragraph">
-<p>We also put the CIF/SVG declarations for the visualization inside the automaton
-definition. By doing this, we ensure that each instantiation (each lamp) gets
-their own version of these declarations.</p>
-</div>
-<div class="paragraph">
-<p>The CIF/SVG declarations have changed as well. A
-<a href="#tools-cifsim-output-svgviz-chapter-svgcopy">CIF/SVG copy declaration</a> has been added. The copy
-declaration states that the SVG element with id <code>lamp</code> (the circle) should
-be copied. It also states that the copy should be postfixed with
-<code><string>nr</code>. That is, for automaton <code>lamp1</code>, the value of the <code>nr</code>
-parameter is <code>1</code>, and the id is thus postfixed with <code>"1"</code>. In other words,
-circle <code>lamp</code> is copied, and the copy is given name <code>lamp1</code> (composed
-from <code>lamp</code> and <code>1</code>). For <code>lamp2</code>, the id of the copied circle is
-<code>lamp2</code>, etc. For each of the lamps, the copy gets a different name, that is
-unique within the SVG image. This single copy declaration takes care of the
-scalability of the SVG image, by ensuring we have exactly as many circles as we
-have lamps (not counting the template circle <code>lamp</code>).</p>
-</div>
-<div class="paragraph">
-<p>The copies of the template circle all get exactly the same attributes as the
-template (except for their <code>id</code> attribute). As such, they are all positioned
-outside the visible part of the canvas. The easiest way to put them at the
-correct positions, is to use a
-<a href="#tools-cifsim-output-svgviz-chapter-svgmove">CIF/SVG move declaration</a>, which
-is also new compared to the previous CIF model. The move declarations use the
-ids of the copied circles, so that each move declaration moves the circle for
-that specific lamp. They are all moved to 20 pixels from the top of the canvas,
-and '20 + (<code>nr</code> - 1) * 100' pixels from the left side of the canvas. So, the
-first lamp (<code>nr</code> 1) is moved to (20, 20), the second lamp (<code>nr</code> 2) is moved
-to (120, 20), and the third lamp (<code>nr</code> 3) is moved to (220, 20). This single
-move declaration takes care of the scalability of the positions of the lamps,
-by ensuring we have exactly as many movements as we have lamps. By using the
-<code>nr</code> parameter, each lamp can easily be moved to their own unique position.</p>
-</div>
-<div class="paragraph">
-<p>The output mappings for the background color of the circles and thickness of
-the borders of the circles, are very similar to the output mappings of the
-first version of the CIF model, though there are a few changes. The mappings
-use the same method as the move declaration, to construct the ids. Since the
-mappings are now defined within the automaton definition, they can directly
-refer to the <code>on</code> variable. This ensures that for each different lamp, the
-mappings refer to the <code>on</code> variable of that specific lamp. We now have only
-one output mapping for the background color, and also only one output mapping
-for the thickness of the border.</p>
-</div>
-<div class="paragraph">
-<p>By putting the CIF/SVG declarations inside the automaton definition, and by
-using the copy and move declarations, we now have a scalable solution. We only
-have one lamp in our SVG image, only one behavioral specification in the CIF
-model, and only one output mapping per attribute that we want to couple. No
-matter how many instantiations of the <code>Lamp</code> automaton definition we add, we
-don’t have to manually change the SVG image or the visualization coupling.</p>

-<p>By default, if plot visualization is enabled, all variables (officially
-'state objects') that can be plotted are plotted. The one exception is variable
-<code>time</code>, which is excluded by default, as it already represents the x-axis.
-That is, variables are plotted against time. Using the
-<b class="menuref">Plot visualization filters</b>
-option
-(<b class="menuref">Output: Plot visualization</b>
-category), the state objects can
-be filtered. The
-<b class="menuref">Plot visualization filters</b>
-option only has effect
-if plot visualization is enabled, using the
-<b class="menuref">Plot visualization</b>
-option.</p>
-</div>
-<div class="paragraph">
-<p>As value for the option, comma separated <em>filters</em> should be supplied. Each
-filter specifies one or more state objects. The absolute names of the objects
-are used. That is, for an automaton <code>a</code>, with a variable <code>x</code>, the absolute
-name of the variable object is <code>a.x</code>. If CIF textual syntax keyword are
-used as names for events (such as <code>plant</code>), then they must be escaped in
-<code>.cif</code> files (<code>$plant</code>). For filters however, all escape characters (<code>$</code>)
-in the names are ignored. The <code>*</code> character can be used as wildcard, to
-indicate zero or more characters. If a filter doesn’t match any of the state
-objects of the CIF model, a warning is printed to the console. A warning is
-also printed if the entire state is filtered out.</p>
-</div>
-<div class="paragraph">
-<p>By default, filters include matching state objects. Filters may however be
-preceded by a <code>-</code> character, turning them into exclusion filters, which
-exclude matching states objects rather than including them. Filters are
-processed in the order they are specified, allowing for alternating additions
-and removals. If a filter does not result in the addition/removal of any state
-objects to/from the filter result, a warning is printed to the console.</p>
-</div>
-<div class="paragraph">
-<p>As an example, option value <code>a.*,-a.b*,a.bc*</code> consists of three filters:
-<code>a.*</code>, <code>-a.b*</code>, and <code>a.bc*</code>. The first filter indicates that state
-objects whose absolute names start with <code>a.</code> are to be included. The second
-filter indicates that from those matching state objects, the state objects
-whose absolute names start with <code>a.b*</code> are to be excluded. To that result,
-the third filter adds those state objects whose absolute names start with
-<code>a.bc*</code>. For instance, if a specification contains state objects <code>time</code>,
-<code>a.a</code>, <code>a.b</code> <code>a.bb</code>, <code>a.bc</code>, <code>a.b.c</code>, <code>a.bc</code>, <code>a.bcc</code>, and
-<code>a.bcd</code>, the result of the three filters is that the following state objects
-are displayed: <code>a.a</code>, <code>a.bc</code>, <code>a.bc</code>, <code>a.bcc</code>, and <code>a.bcd</code>.</p>

-<p>As value for the option, comma separated <em>filters</em> should be supplied. Each

-<p>By default, filters include matching state objects. Filters may however be

-filter indicates that from those matching state objects, the state objects
-whose absolute names start with <code>a.b*</code> are to be excluded. To that result,

-<div class="paragraph">
-<p>
-
-
-The CIF simulator allows for a form of real-time simulation. By enabling
-real-time simulation, the simulator interprets the model time (the value of
-variable <code>time</code>) in seconds. The simulator attempts to ensure that the actual
-simulation time is equal to the model time. This feature is very useful for
-visualizers, which then visualize their output at a steady rate. Without
-real-time simulation, the rate at which such visualizers would visualize their
-output, would primarily be determined by the amount of time it takes for the
-simulator to compute the output, leading to abrupt slow downs and sudden speed
-increases.</p>
-</div>
-<div class="paragraph">
-<p>
-</p>
-</div>
-<div class="sect6">
-<h7 id="tools-cifsim-output-realtime-frames">Frames</h7>
-<div class="paragraph">
-<p>If real-time simulation is disabled, visualizations are only updated for the
-<a href="#tools-cifsim-traces-state">states</a> that are reached. That is, the
-visualizations are updated for the initial state, and each new state that is
-reached after taking a transition. The visual representations of the
-visualizations resulting from these states are called <em>frames</em>.</p>
-</div>
-<div class="paragraph">
-<p>As time progresses, the values of continuous variables (and algebraic variables
-for which the value is directly or indirectly derived from a continuous
-variable, etc) change. If the visualization is only updated before and after
-time transitions, as is done when real-time simulation is disabled, this leads
-to 'jumps' in the visualization. For real-time simulation, the simulator
-calculates states that are evenly spaced over time. This ensures that we get
-regular updates of the visualizations, as time progresses, and the
-visualizations thus become 'smooth' or 'fluent'. If enough states are
-visualized per second, a visualization essentially becomes a <em>movie</em>.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-
-The states that result from transitions are always calculated. For real-time
-simulation, the simulator calculates additional states for the purpose
-of visualization, as mentioned above. These additional states are called
-<em>intermediate states</em>, and the corresponding visual representations of the
-visualizations to which they lead are called <em>intermediate frames</em>.</p>
-</div>
-<div class="paragraph">
-<p>For real-time simulation, the simulator thus uses intermediate frames that are
-evenly spaced over time, for smooth visualizations. A consequence of this, is
-that state changes between those intermediate frames are lost. If the effect is
-still visible in the next intermediate state, this is not a problem. If however
-the effect is temporary, and does not last until the next intermediate state,
-the effect is thus not visualized.</p>
-</div>
-<div class="paragraph">
-<p>For real-time simulation combined with an interactive
-<a href="#tools-cifsim-input-chapter-index">input mode</a>, the
-simulator uses both the state frames and the intermediate frames. This ensures
-that at the moment an interactive choice has to be made about which
-transition to take, the visualization reflects the current state of the system.
-Semi-automatic mode is not taken into account.</p>

-<p>Using the

-option (<b class="menuref">Output</b>
-category), it is
-possible to specify how often per second of real time, visualizations should
-be updated. A higher frame rate leads to more updates per second, and thus to
-a more fluent visualization. However, since a higher frame rate also leads to
-more frequent updates, the amount of CPU power it takes to perform these
-updates increases as well. If the computer can not update the visualization in
-time for the next update to take place, the visualization may start to
-'stutter'.</p>
-</div>
-<div class="paragraph">
-<p>
-The frame rate will thus always be a compromise between fluency and
-performance. Choosing an appropriate frame rate depends not only on the
-complexity of the specification being simulated and the visualization that is
-being shown, but also on the computer on which the simulation is run.
-Furthermore, it may depend on the other tasks the computer is performing while
-the simulation is being run.</p>
-</div>
-<div class="paragraph">

-Similarly, it can hinder
-<a href="#tools-cifsim-chapter-termination">termination</a> of the simulation, as the red

-One of the simplest root finding algorithms, is the
-<a href="http://en.wikipedia.org/wiki/Bisection_method">bisection method</a>.
-This algorithm starts with
-the two time points where the guard has opposite
-<a href="http://en.wikipedia.org/wiki/Sign_%28mathematics%29">signs</a>.
-This is the interval
-where the guard sign change occurs (it contains the root). The bisection method
-tries to reduce the size of the interval, by calculating the value of the guard
-in the middle of the interval. Depending on the sign of the value of the guard
-at this middle point, this middle point replaces either the lower bound or the
-upper bound of the interval. This is done in such a way that the values of the
-guard at the lower and upper bound of the interval have opposite signs, and the
-interval thus <em>brackets</em> the root.</p>
-</div>
-<div class="paragraph">
-<p>For the example above, the root is calculated as follows:</p>

-<div class="imageblock">
-<div class="content">
-<img src="./tools/cifsim/solver/root_root.png" alt="root root">

-<div class="paragraph">
-<p>We start with the interval <code>[1.1111 .. 5.0]</code>. The middle point is <code>3.0555</code> at which
-the guard holds, just like the upper bound (at <code>5.0</code>). Thus <code>5.0</code> is replaced by
-<code>3.0555</code>. The middle point of <code>1.1111</code> and <code>3.0555</code> is <code>1.5972</code>. Since the guard holds
-for time <code>1.5972</code>, upper bound <code>3.0555</code> is replaced by <code>1.5972</code>. The middle point
-of <code>1.1111</code> and <code>1.5972</code> is <code>1.3542</code>. The guard does not hold at time <code>1.3542</code>, so the
-lower bound of <code>1.1111</code> (at which the guard does not hold) is replaced by <code>1.3542</code>.
-This process continues until the interval is smaller than a certain tolerance
-value. Once we have that interval, we can choose a value from the interval as
-the computed root.</p>

-<p>While the bisection method is relatively simple, the root finding algorithms

-<div class="paragraph">
-<p>The first solution is to use the
-<b class="menuref">ODE solver root finder maximum check interval</b>
-option (<b class="menuref">ODE solver: ODE root finder</b>
-category). This
-option can be used to set the maximum time interval between two consecutive
-checks of the sign of the guard. By default, this is <code>0.5</code> time units. If we
-set this value to <code>0.001</code>, then we ensure that at least once every <code>0.001</code>
-time units, the guard sign is checked. This means that between time points
-<code>2.1111</code> and <code>2.61111</code>, the guard will be checked approximately 500 times.
-This also means that between time points <code>2.33</code> and <code>2.34</code>, the guard will
-be checked approximately 10 times. Therefore, this ensures that we check a time
-point just before time <code>2.33</code>, and one just after it, which means we can’t
-miss the guard change.</p>
-</div>
-<div class="paragraph">
-<p>In the above example, <code>x'</code> is <code>1.0</code>. If however <code>x'</code> would be <code>2.0</code>,
-then the time interval where the guard is enabled reduces from <code>0.01</code> time
-units to <code>0.005</code> time units. Using a maximum check interval of <code>0.001</code>
-would then still suffice, as the guard would be checked approximately 5 times
-in that time interval. If however <code>x'</code> is <code>100</code>, then the time interval
-would become <code>0.0001</code>, which is smaller than the maximum check interval of
-<code>0.001</code>. That is, the derivatives of the values occurring in guards influence
-the value that should be chosen for the maximum delay interval.</p>
-</div>
-<div class="paragraph">
-<p>In general, to choose an appropriate value for the maximum check interval, not

-<pre class="CodeRay highlight"><code data-lang="cif">automaton p:
- cont x = 0.0;

-<img src="./tools/cifsim/solver/root_problem2.png" alt="root problem2">
-</div>
-</div>
-<div class="paragraph">
-<p>The difference with the original specification is the guard of the edge. In the
-original specification, the <code>and</code> binary operator is used, making it a single
-guard. In the new specification, a comma (<code>,</code>) is used, which constructs two
-separate guards. Both guards can be individually checked by the root finding
-algorithm. As shown in the image, each of the guards changes value only once.</p>
-</div>
-<div class="paragraph">
-<p>The comma between guards means that both guards have to hold, in order for the
-edge to be enabled. This is similar, but not identical, to the <code>and</code> binary
-operator. For the <code>and</code> binary operator, the left hand side must be evaluated
-before the right hand side, and the right hand side may only be evaluated if
-the left hand side evaluates to <code>true</code>. This is called
-<a href="http://en.wikipedia.org/wiki/Short-circuit_evaluation">short-circuit evaluation</a>.
-For guards separated by commas, no such relation may be assumed. That is, even if
-the first guard evaluates to false, can the second guard still be evaluated by
-the root finding algorithm, for guard changes. It can even be the case that the
-second guard is evaluated before the first guard. These differences not only
-influence root finding, but are also of particular interest when the right hand
-side can result in a runtime evaluation failure. For instance, the following
-specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="cif">automaton p:
- cont x der 1.0;

-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>results in a runtime error. The second guard (<code>1 / x < 0.5</code>) is evaluated
-even if the first guard (<code>x > 0</code>) does not hold. Initially, the first guard
-does not hold, and the second guard results in division by zero. Changing the
-comma between the guards to an <code>and</code> operator, makes it possible to simulate

-Linux/Mac path separators (<code>/</code>) and Windows path separators (<code>\</code>) may be

-</div>
-<div class="paragraph">
-<p>The method is resolved in the Java Virtual Machine (JVM) that runs the

-<p>The randomness of the stochastic distributions is implemented in the CIF

-<a href="http://en.wikipedia.org/wiki/Mersenne_twister">Mersenne Twister</a>.
-The sequences of

-</div>
-<div class="paragraph">
-<p>Since the sequence of generated random numbers is always the same, the only

-</div>
-<div class="paragraph">
-<p>The initial seed as provided by the option, is used for the first stochastic

-<div class="paragraph">
-<p>Besides the general application options, this application has the following
-options:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p><em>Input file path</em>: The absolute or relative file system path to the input
-CIF specification.</p>
-</li>

-<p><em>Instance tree definition</em>: mCRL2 uses a tree of processes which you can
-specify manually here. If not specified, it takes the default solution,
-which first merges all CIF automata (one at a time), and on top of that, the
-variable processes of the shared variables (also one at a time).
-How to define your own tree is explained in the
-<a href="#tools-cif2mcrl2-instancetree-syntax">instantiation tree syntax</a> Section.</p>
-</li>
-<li>
-<p><em>Enable debug output</em>: The transformer derives information about used and
-available variables in the instantiation tree, and uses that information to
-generate the mCRL2 action operations at every level. By enabling this
-option, this information is also written to an output file for further
-external analysis. By default, the information is written in a file with the
-same name as the input file, except first the <code>.cif</code> extension is removed
-(if present), and a <code>_dbg.txt</code> extension is appended. The name of the
-output file can be changed with the <em>Debug output file path</em> option. Setting
-the latter option enables this option.</p>
-</li>
-<li>
-<p><em>Debug output file path</em>: The absolute or relative file system path to use
-for writing derived information about used and available variables at every
-level in the instantiation tree. Setting this option changes the debug
-output file path to the given path. It also enables the <em>Enable debug
-output</em> option.</p>
-</li>
-<li>
-<p><em>Output file path</em>: The absolute or relative file system path for writing
-the generated mCRL2 output file. By default, the output file path is the
-same as the input file path, but with the <code>.cif</code> extension removed (if it
-exists), and the <code>.mcrl2</code> extension added. By setting this option, the
-default is overridden by the given value.</p>
-</li>
-<li>
-<p><em>Generate 'value' actions</em>: To query the value of variable <code>x</code>,
-a <code>value_x</code> action can be used. By default, such actions are generated for

-available anyway increases the amount of work that has to be done by the mCRL2

-</div>
-<div class="paragraph">
-<p>The option takes a comma separated list of variable patterns. Each pattern

-<h5 id="tools-cif2mcrl2-instancetree-syntax">Syntax of the instance tree</h5>
-<div class="paragraph">
-<p>In mCRL2, a behavior process is required for every automaton in the input, and
-a variable process is needed for every variable used (read or written) by two
-or more automata. In addition, it is allowed to have a variable process for
-variables that are used in one automaton only (that is, a local variable of
-the automaton).</p>
-</div>
-<div class="paragraph">
-<p>All these processes must be instantiated using the parallel composition
-operator. For larger specifications, the naive solution of instantiating all
-processes together in one level fails due to having too many allowed
-combinations of actions for the mCRL2 tool to handle.</p>
-</div>
-<div class="paragraph">
-<p>A different solution is to instantiate smaller groups of processes at a time,
-and then use these groups again in other instantiations. Instantiation happens
-in multiple levels in this case, leading to a tree of process instantiations.
-At each level, the set of allowed actions is restricted by adding action
-operators. This results in a large reduction of the number of possible
-combinations of actions that need to be explored by the mCRL2 tool. Fewer
-combinations of actions in turn leads to enabling larger specifications to be
-verified.</p>
-</div>
-<div class="paragraph">
-<p>Which processes and groups are taken together at each level in the tree has a
-large impact on feasibility. The CIF to mCRL2 transformer has a default
-scheme, where pairs of one group and one behavior process are taken together
-at each level (except at the bottom, where two behavior processes are merged
-instead). On top of that tree, pairs of a group and a variable process are
-taken together.</p>
-</div>
-<div class="paragraph">
-<p>The CIF to mCRL2 transformer does not perform analysis to decide how processes
-and variables should combined. In many cases this provides a working solution.
-For some specifications however, you may want to have more influence in the
-order of grouping. For this reason, the <em>Instance tree definition</em> option
-exists. It allows you to define which processes should be taken together at
-each level in the instantiation tree.</p>
-</div>
-<div class="paragraph">
-<p>The current implementation has limits with respect to ordering. Automata
-processes must be merged first (but the number of levels and the order of
-combining is free), and then variables must be added one at a time (but which
-variable to use at each level is free).</p>
-</div>
-<div class="paragraph">
-<p>The option expects absolute names of all automata in the specification and
-absolute names of all discrete variables used in two more automata, separated
-by white space or commas. In addition you may add the absolute names of
-variables used in only one automaton. For each element mentioned, a process is
-created in mCRL2. Variables used in one automaton that are not mentioned,
-become local variables of the behavior process of the automaton that uses the
-variable.</p>
-</div>
-<div class="paragraph">
-<p>Processes for the mentioned CIF elements are instantiated. Sub-groups of
-processes are written by surrounding them with parentheses. For example:</p>

-<p>CIF features synchronizing events, while UPPAAL only supports channels. A
-<code>SendAut</code> automaton/template is added to the UPPAAL system to ensure proper
-event synchronization. The UPPAAL template has a single location, and self
-loops for every event in the CIF specification. The guards of the self loops
-express the conditions under which the events are globally enabled (guard wise)
-in the CIF specification. Every CIF event is a broadcast channel in UPPAAL. If
-the self loop is enabled (guard wise), the <code>SendAut</code> template broadcasts over
-the channel. All the other templates (for the CIF automata) receive the event.
-They can actually receive, as the guard of the self loop ensures that. Together
-the <code>SendAut</code> self loops and the receive edges form the synchronization.</p>
-</div>
-<div class="paragraph">
-<p>As the <code>SendAut</code> template needs to refer to locations of the other templates,
-location pointer variables are added for all the other templates. For every
-CIF automaton <code>some.aut</code>, a location pointer variable <code>LP_some_aut</code> is
-added. The location pointers are integer variables with range <code>[0,n-1]</code>, for
-an automaton with <code>n</code> locations. Updates are added to the edges to ensure the
-location pointer variables have the proper values. The location pointers are
-similar to those created by the CIF to CIF transformation that
-<a href="#tools-cif2cif-chapter-elim-locs-in-exprs">eliminates the use of locations in expressions</a>.</p>
-</div>
-<div class="paragraph">
-<p>In CIF, assignments interpret the right hand side of the assignment (the new
-value of the variable) in the source state of the transition. In UPPAAL,
-assignments have order, and the right hand sides are interpreted over the
-current state, after any preceding assignments. Furthermore, the order in which
-the assignments of the edges of different participating templates are executed
-is not defined. To ensure the proper CIF semantics, 'old' versions of all
-variables (including the location pointer variables) are added. For a variable
-<code>x</code>, <code>OLD_x</code> is added. The <code>SendAut</code> automaton assigns the current values
-of all variables to their 'old' counterparts. The assignments on the edges of
-the other automata then use the 'old' variables to compute the new values of
-the variables. As the values of the 'old' variables are only used during the
-transitions, the 'old' variables are <em>meta</em> variables in the UPPAAL system.</p>

-<p>The names of templates, variables, etc in UPPAAL are based on the absolute

-<div class="sect5">
-<h6 id="tools-code-overview">Code overview</h6>
-<div class="paragraph">
-<p>The code that executes the edges of the CIF model is called the <em>event loop</em>
-code. The event loop is not the only code that is executed. Before the loop,
-the values of the input variables are obtained from the environment, the
-initial state is initialized (for the first execution only), and the values of
-the continuous variables are updated to account for the amount of time that has
-passed (for all but the first execution). Then the event loop is executed.
-Finally, output values may be supplied to the environment.</p>
-</div>
-</div>
-<div class="sect5">
-<h6 id="tools-repeated-execution">Repeated execution</h6>
-<div class="paragraph">
-<p>During the execution of the code, variable <code>time</code> from the CIF model is
-not updated. Execution of the code takes time. After the code is executed,
-potentially more time passes. Then, the code can be executed again. The time
-(in seconds) between the first execution and the current execution is the
-total time that has passed since execution started, and this becomes the new
-value of variable <code>time</code>.</p>
-</div>
-<div class="paragraph">
-<p>How often the code is executed, and whether this is done with a fixed cycle
-time (periodic task scheduling) or with a variable cycle times (non-periodic
-tasks) can be influenced by the end user. The details differ per target
-language, and can be found on their respective pages.</p>
-</div>
-</div>
-<div class="sect5">
-<h6 id="tools-event-loop">Event loop</h6>
-<div class="paragraph">
-<p>The CIF model is first <a href="#tools-cif2cif-chapter-linearize-merge">linearized</a> to
-eliminate parallel composition. The result is self loop edges with guards and
-updates. The main part of the generated code essentially consists of update
-code that is conditionally executed. This code executes edges. This is done
-repeatedly, until no more events are enabled. The loop in the generated code
-that repeatedly executes event code until no more events are possible, is
-called the <em>event loop</em>. Once no more events are enabled, the event loop
-terminates.</p>
-</div>
-</div>
-<div class="sect5">
-<h6 id="tools-event-order">Event order</h6>
-<div class="paragraph">
-<p>The order in which the code is generated for the different edges (in the
-<em>event loop</em>), is done in such a way that it matches the order in which
-transitions are chosen by the simulator. Assuming the simulator is used to
-simulate by always automatically choosing the
-<a href="#tools-cifsim-input-chapter-automatic">first transition</a> that is enabled, the
-generated code will choose that same transition. That is, for each iteration of
-the event loop, the code is executed for the first event with an enabled guard.
-Then, a new iteration of the loop is started, from the top, to ensure that the
-first enabled event is always executed, similar to simulation. If during an
-iteration of the loop none of the events is enabled, the event loop terminates.</p>
-</div>
-</div>
-<div class="sect5">
-<h6 id="tools-termination-2">Termination</h6>
-<div class="paragraph">
-<p>If in the CIF model always at least one event is enabled, the generated code
-will run forever, and will never terminate. Time will not pass. Code generation
-should be avoided for such models. It is the responsibility of the modeler to
-ensure this is taken into account.</p>
-</div>
-</div>
-<div class="sect5">
-<h6 id="tools-predictability-of-execution-time">Predictability of execution time</h6>
-<div class="paragraph">
-<p>If at least one event is enabled, the event loop is executed again. If during
-an iteration of the loop none of the edges is enabled, the loop terminates.
-This approach generally does not result in predictable execution times of the
-program body. That is, if a certain edge keeps being enabled, the loop is
-executed over an over again. In that case, the execution time of the body
-may exceed the fixed cycle time, and the controller is no longer guaranteed to
-work correctly. Even if the loop is only executed a finite number of times,
-the execution time of the body may exceed the fixed cycle time. One may
-consider monitoring the execution times to detect such issues. All
-implementations provide a way to obtain execution time statistics. The details
-differ per target language, and can be found on their respective pages.</p>
-</div>
-</div>
-<div class="sect5">
-<h6 id="tools-optional-execution-feedback">Optional execution feedback</h6>
-<div class="paragraph">
-<p>Several implementations provide additional information during simulation, such as
-which events have been executed, timing information, and what new print output
-has been generated. Such information can generally be enabled and disabled in
-the implementations. The details differ per target language, and can be found
-on their respective pages.</p>

-<h6 id="tools-correct-handling-of-io">Correct handling of I/O</h6>
-<div class="paragraph">
-<p>The generated code cannot guarantee its correct behavior if the inputs from the
-external I/O change more rapidly than the generated code is executed. That is,
-if an input changes during a single execution of the code, the change is not
-noticed until the next execution. If an input changes during an execution and
-changes back during that same execution, the change is not noticed at all.
-Therefore, executing the code often enough per second, is essential. In other
-words, choosing an appropriate cycle time is essential for the correct
-functioning of the generated code.</p>

-<p>The generated C89, C99 and Java code maintains the running time in seconds.
-Due to the finite
-representation of numeric values, this results in numeric overflow after
-execution for a long time. Running the code continuously for longer than 100
-years should be avoided.</p>
-</div>
-<div class="paragraph">
-<p>The continuous variables from the CIF specification in the generated code
-are updated each execution
-using the <a href="http://en.wikipedia.org/wiki/Euler_method">Euler method</a> for
-integration. That is, each execution the time that has elapsed since the
-previous execution is multiplied by the derivative of the continuous variable
-in the state of the previous execution. This value is added to the value of the
-continuous variable. Essentially, a linear approximation of the derivative is
-used, calculated using the state of the previous execution.</p>
-</div>
-<div class="paragraph">
-<p>The Euler method can be
-<a href="http://en.wikipedia.org/wiki/Numerical_stability">numerically unstable</a>, it
-can suffer from rounding
-errors due to the use finite binary representations of real values, and has
-some other issues as well. The effects are likely to be limited if linear
-continuous variable (continuous variables with constant derivatives) are used.
-Especially clocks (derivative +1 or -1) generally don’t suffer too much from
-these issues. However, even clocks may suffer from loss of accuracy over time.
-As such, clocks should not be used to measure over long periods of time.

-specific information applicable only to Simulink code generation.</p>
-</div>
-<div class="paragraph">
-<p>The aim of the the conversion from CIF to Simulink is to provide a smooth path

-</div>
-<div class="paragraph">
-<p>At this page, all the details about the Simulink code generation are discussed.
-For an example of how to use this code generation in practice, read

-<div class="sect5">
-<h6 id="tools-supported-specifications-9">Supported specifications</h6>
-<div class="paragraph">
-<p>The CIF code generator supports a subset of CIF specifications. See the
-<a href="#tools-codegen-supported">Supported specifications</a> section of the <a href="#tools-codegen-chapter-index">CIF code generator</a> page
-for more information. Generation of Simulink S-Function C code adds
-a restriction to the type of CIF input variables caused by limitations in
-Simulink input ports.</p>
-</div>
-<div class="paragraph">
-<p>Simulink input ports can only handle real and complex signals. The latter
-cannot be expressed in CIF, while the former creates the need for CIF input
-variables with data types that can be relatively easily converted to real
-number values. For this reason, CIF input variables must have a boolean,
-enumeration, integer, or real elementary type. Arrays (fixed length CIF lists)
-of these elementary types are also supported, they are converted to a vector
-of real numbers at a Simulink input port. Finally, arrays of arrays of the
-elementary types are converted to a matrix of real numbers at a Simulink input
-port.</p>
-</div>
-<div class="paragraph">
-<p>Data types of all other CIF variables have no additional constraints. However,
-Simulink poses similar restrictions to its other data vectors, in particular
-the output ports. The CIF to Simulink code generator toool only makes
-variables available for output that are compatible with real number, vectors
-of real numbers, or matrices of real numbers.
-That means that use of the CIF string type, the tuple type, or arrays with
-a deeper nesting than two levels will not be available at the output.</p>
-</div>
-</div>
-<div class="sect5">
-<h6 id="tools-differences-in-output-3">Differences in output</h6>
-<div class="paragraph">
-<p>When converting a real number to text, for example when printing a real value,
-the generated Simulink code does not preserve trailing zeroes of real number
-fractions while using <code>%g</code>. For example <code>fmt("%.3g", 1.0)</code> will output
-<code>1</code> rather than <code>1.000</code>.
-This may cause real number values to be printed with less digits precision than
-indicated in the CIF program.</p>
-</div>
-<div class="paragraph">
-<p>Strings have an upper limit in length that is set during compilation. Longer
-strings are silently truncated to this length.</p>
-</div>
-<div class="paragraph">
-<p>The CIF print statement is supported, but only for the <code>:stdout</code> file. It
-is translated to the <code>ssPrintf</code> C function. This is also the only way to get
-a string to appear outside the Simulink S-Function block. Note that Simulink
-may drop the output function for platforms that have no output possibilities.</p>

-algebraic variables can be selected. The option also allows to use the
-wildcard character <code>*</code>, which represents zero or more characters from the
-name. You can use it to match several variables at once, for example
-<code>*out</code> matches all variables that end with <code>out</code>. The special name
-<code>nothing</code> means that no output should be produced at all.</p>

-<p><em>Simulink sample time</em>: This option controls how Simulink samples the

-<code>variable</code>, or a sample period. Check the Mathworks <code>ssSetSampleTime</code>
-function documentation for details which to use. By default, sample time is
-set to <code>continuous</code>.</p>

-priority must be in the range [0 .. 65535], where priority 0 is the highest
-priority, and priority 65535 is the lowest priority. The priority can be used
-for preemptive or non-preemptive scheduling. If not specified, the priority

-<p>The bodies of the programs and functions in the generated PLC code use
-Structured Text as programming language. Structured Text is one of the
-programming languages that is part of the IEC 61131-1 standard.</p>
-</div>
-<div class="paragraph">
-<p>The generated code contains a single program called <code>MAIN</code>. This program is
-instantiated in a task, which is part of a resource, which in turn is part of
-a configuration. The configuration is put in a project, but that is outside
-the range of the IEC 61131-3 standard. Most implementations however, work with
-projects. The effect of the project, configuration, resource, and task is
-dependent on the <a href="#tools-cif2plc-output-type">output type</a>. Besides a
-program, the code generator also generates data types, functions, and global
-variables.</p>
-</div>
-<div class="paragraph">
-<p>For algebraic variables, functions are generated that are parametrized over the
-state of the system. Similarly, functions are generated for the derivatives of
-the continuous variables. For the discrete and continuous variables (including
-variable <code>time</code>), a <code>STRUCT</code> data type named <code>STATE</code> is generated that
-holds the entire state of the system (or more precisely, the
-<a href="#tools-cifsim-traces-state">state</a> of the CIF specification). For input variables,

-</div>
-<div class="paragraph">
-<p>For invalid CIF specifications, the resulting code may not always behave as the

-<h5 id="tools-cif2plc-names">Names</h5>
-<div class="paragraph">
-<p>The generated PLC code will contain names for functions, variables, locations
-of automata, etc. The absolute names of all objects are used. The names are
-influenced by the <a href="#tools-cif2cif-chapter-linearize-merge">linearization</a>
-algorithm. They are further influenced by the PLC code generator.</p>
-</div>
-<div class="paragraph">
-<p>The code generator ensures unique names in the generated PLC code, taking into
-account the reserved names (keywords, standard functions, etc) of the IEC
-61131-3 standard and some of the common implementations of that standard. To
-avoid reserved names, names are prefixed with prefixes that depend on the type
-of object (for instance, <code>dvar_</code> for discrete variables). Furthermore, it
-takes into account that names in CIF are case sensitive, while they are case
-insensitive in IEC 61131-3. The code generator computes a candidate name based
-on these criteria.</p>
-</div>
-<div class="paragraph">
-<p>If this results in duplicate names, renaming is performed. A common reason for
-renaming is different locations (of the same automaton or of different
-automata) that have the same name, but in different casing. For instance,
-consider one location named <code>WaitForTimeout</code> and another named
-<code>WaitForTimeOut</code>. After linearization, there is an enumeration with a literal
-for each unique location name. The enumeration thus has at least two literals,
-named <code>WaitForTimeout</code> and <code>WaitForTimeOut</code>. The candidate names for these
-enumeration literals are <code>elit_WaitForTimeout</code> and <code>elit_WaitForTimeOut</code>.
-However, they are identical except for casing. Thus, the first one that is
-encountered during code generation gets the candidate name, and the second one
-is renamed. This results in a warning like this:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="console">WARNING: PLC variable "elit_WaitForTimeout" is renamed to "elit_WaitForTimeout2".</code></pre>

-<div class="paragraph">
-<p>Renaming may be needed to ensure valid functioning output. However, it may make
-it slightly more difficult to trace names in the generated PLC code back to the
-original CIF model. Also, in the PLC environment, when debugging the current
-values of variables may be shown. If enumeration literals are renamed, the
-renamed names may then be shown in the debugger. By default, the PLC code
-generator does not inform the user when renaming takes place. By enabling the
-<em>Rename Warnings</em> option, a warning will be printed to the console, each time
-a PLC name is renamed.</p>

-does not require any vendor specific extensions, functions, or data types.
-The generated code works for fixed cycle times (periodic task scheduling) as
-well as variable cycle times (non-periodic tasks).</p>
-</div>
-<div class="paragraph">
-<p>During the first cycle, the variables of the state are initialized to their
-proper values. For subsequent cycles, the state resulting from the previous
-cycle is reused, where the values of the continuous variables are updated to
-account for the time that has passed since the beginning of the previous cycle.
-For details on the method used to update the values of the continuous
-variables, see the <a href="#tools-cif2plc-accuracy">Accuracy over time</a> section.</p>
-</div>
-<div class="paragraph">
-<p>The loop at the end of the body evaluates the guard of each of the events of
-the CIF specification. If a guard holds, the corresponding update is performed.
-Code is generated for the events, or rather the edges, in the order that they
-occur in the <a href="#tools-cif2cif-chapter-linearize-merge">linearized</a> CIF
-specification. Linearization is performed in such a way, that the PLC code that
-is generated from it, has a correspondence to the simulator. Assuming the
-simulator is used to simulate by always automatically choosing the
-<a href="#tools-cifsim-input-chapter-automatic">first transition</a> that is enabled, the
-PLC code will choose that same transition. That is, for each iteration of the
-event loop, the code is executed for the first event with an enabled guard.
-Then, a new iteration of the loop is started, from the top, to ensure that the
-first enabled event is always executed, similar to simulation. If during an
-iteration of the loop none of the events is enabled, the loop terminates.</p>
-</div>
-<div class="paragraph">
-<p>If at least one event was enabled, the loop is executed again. If during an
-iteration of the loop none of the edges was enabled, the loop terminates. This
-approach generally does not result in predictable execution times of the
-program body. That is, if a certain edge keeps being enabled, the loop is
-executed over an over again. In that case, the execution time of the body
-exceeds the fixed cycle time, and the controller is no longer guaranteed to
-work correctly. Even if the loop is only executed a finite number of times,
-the execution time of the body may exceed the fixed cycle time. One may
-consider monitoring the execution times to detect such issues.</p>
-</div>
-<div class="paragraph">
-<p>
-Within the 'event loop', a counter is used to detect how often the loop is
-repeated. After the loop is executed a 100 times, the loop is terminated, to
-ensure that the body terminates in the case of events that are always possible.
-In such a cases, variable <code>loopsKilled</code> is incremented by one, for debugging.
-While by default the loop is terminated after 100 iterations, this maximum
-number of iterations can be configured using the
-<b class="menuref">PLC maximum iterations</b>
-option (<b class="menuref">Generator</b>
-category). The
-option can also be set to infinite, to not impose a restriction, and never

-</div>
-<div class="paragraph">
-<p>Obviously, similar to the fact that the controller cannot guarantee its correct
-behavior if the execution time of a cycle exceeds the cycle time, the
-controller also cannot guarantee its correct behavior if the inputs from the
-external I/O change more rapidly than the cycle time. That is, if an input
-changes during a cycle, the change is not noticed until the next cycle. If an
-input changes during a cycle and changes back during that same cycle, the

-<p>
-
-The CIF to CIF transformer can be used to syntactically transform CIF
-specifications to similar CIF specifications, which behave in the same
-manner (are semantically equivalent), but are expressed using different
-language constructs. For example, the CIF to CIF transformation that
-eliminates constants, replaces all uses of constants by their values,
-and removes the constants from the specification.</p>
-</div>
-<div class="paragraph">
-<p>These reusable transformations are primarily used to increase the subset
-of CIF specifications that can be transformed or processed.
-Usually, there is no need to apply the CIF to CIF transformations manually.
-Transformations that work on subsets of the CIF language, automatically
-apply the necessary CIF to CIF transformations as a preprocessing step, to
-increase the translatable subset.</p>

-<p>They are replaced with automata with self loops. Per component, the state/event
-exclusion invariants of the component (the top level scope of the

-<a href="#lang-tut-extensions-synthesis-invkind">supervisory kind</a>. Per such

-<p>The automaton is put along side the component (for groups and automata), as

-automaton is put in the top level scope of the specification. The new automaton
-gets the same name as the component that contained the invariants as prefix,
-with some postfixes. For invariants at the top level scope of the
-specification, an empty prefix is used. The first postfix is indicates the
-supervisory kind of the invariants of the partition: <code>Plant</code>,
-<code>Requirement</code>, <code>Supervisor</code>, or empty for regular/kindless invariants.
-The second postfix is <code>StateEvtExcls</code>. So, for an automaton <code>Abc</code> with
-some plant invariants, an automaton <code>AbcPlantStateEvtExcls</code> is created. The

-<p>For state/event exclusion invariants of the locations of automata, the

-</div>
-<div class="paragraph">
-<p>For state/event exclusion invariants that indicate when an event is to be
-disallowed/disabled, the condition predicate is inverted. The inversion is
-performed after the condition predicate is made condition on the location, if
-applicable. For instance, for a state/event exclusion invariant
-<code>invariant x != 1 disables evt</code> in a location <code>loc</code>, the condition
-predicate <code>x != 1</code> is first made conditional on the location. This results in

-<p>One of the simplifications that the CIF to CIF transformation to
-<a href="#tools-cif2cif-chapter-simplify-values">Simplify values</a> performs, is the evaluation of constant
-(sub-)expressions. For large literal expressions, such as arrays with thousands
-or even millions of elements, this is expensive, without having any effect.
-For instance, consider list/array literal <code>[1, 2, 3]</code>. Evaluating the
-list/array and the integer elements, and then reconstructing the literal
-list/array expression and literal integer expressions, has no effect. The
-result is the same list/array literal as the original.</p>
-</div>
-<div class="paragraph">
-<p>This transformation detects literal expressions, and doesn’t further simplify
-them, thus greatly improving performance for large literal expressions.
-Literal expressions are detected using a static analysis. Due to using static
-analysis, some literals may not be simplified, while they would have been
-simplified if this literal detection optimization was not used. For instance,
-a set literal <code>{1, 2, 1}</code> is simplified to <code>{1, 2}</code> without optimizations,
-and is not simplified with optimizations. In this case, static analysis does
-not account for duplicate elements of the set.</p>

-<p>Negations of integer literals are not normalized, although this only affects

-<li>
-<p>Real literals are not normalized. For instance, <code>1e3</code> is not normalized
-to <code>1000.0</code>.</p>
-</li>
-<li>
-<p>For set literals, duplicate elements are not removed.</p>
-</li>
-<li>
-<p>For dictionary literals, duplicate keys are not removed, and the dictionary
-literal is not further simplified. Without literal optimization, duplicate

-</div>
-<div class="paragraph">
-<p>This transformation however, does not take the values of declarations into
-account, and thus for instance does not fill in the values of constants,
-algebraic variables, etc. Therefore, this transformation transforms that same
-specification into the following simplified specification:</p>
-</div>
-<div class="listingblock">
-<div class="content">

-<div class="paragraph">
-<p>This variant can be useful, as it prevents the use of constants from being
-eliminated. This makes it possible to change the value of the constant in one
-place (the one place being the declaration of the constant), and have all uses
-of that constant automatically change with it (as they still refer to the
-constant). If the value of the constant would be filled in as well, changing
-the value of the constant would be more work, as all those places where it was
-filled in, need to be replaced as well. In the above example, the issue is
-even bigger, as the result is simplified even further, eliminating the entire
-comparison to a single boolean value.</p>
-</div>
-<div class="paragraph">
-<p>Another issue related to simplification of constants, is that inlining them
-can be very expensive. If a constant has a large literal as its value, the
-large literal is inlined wherever the constant is used. This may lead to
-significantly larger specifications. Also, tools that use the resulting model
-may handle constants in a special way to ensure they are evaluated only once,
-but may not do so for large literals that occur in the middle of other
-expressions. As such, simplification/inlining of constants may significantly
-reduce performance.</p>

-<p>The supervisor specification contains three <em>skeletons</em>: groups that only
-contain event declarations, and have no behavior. The skeletons represent the
-plants of the system, which are controlled by the supervisor. The supervisor
-specification also contains a supervisor automaton, which waits for the button
-to be pushed, then turns on the lamp and start the timer, waits for the timer
-to time out, turns the lamp back off, and keeps repeating this behavior.
-Pushing or releasing the button during the cycle has no effect.</p>
-</div>
-<div class="paragraph">
-<p>The timed specification contains the same plants, with the same events, but
-here the plants are actual automata with behavior, instead of just skeleton
-groups. For the button and lamp, the events occur in alternating sequences.
-The timer has a clock that ensures that the timeout happens two time units
-after the timer is started.</p>

-<p>Since both specifications contain the same events (based on their absolute

-events become linked (or coupled), and all refer to the single merged event in
-the merged specification. This means that the events used in the supervisor are
-the same events as used the timed plant. This also means that they synchronize,

-defines the value.</p>

-<h5 id="tools-event-disabler-usage-scenario">Usage scenario</h5>
-<div class="paragraph">
-<p>Assume a system with some sensors and actuators. From the view of the
-supervisor (or controller in general), the sensors are uncontrollable, and the
-actuators are controllable. Now assume a controller is being designed for this
-system, and it is to be merged with a simulation model of the uncontrolled
-system, that is being designed as well.</p>
-</div>
-<div class="paragraph">
-<p>The situation may arise that the controller only controls a part of the
-uncontrolled system. This may for instance be the case if the designer of the
-controller starts with a small controller and incrementally extends it to cover
-more and more functionality of the system. The designer may have already made
-a full simulation model of the uncontrolled system beforehand. Alternatively,
-if one designer develops the controller and another develops the simulation
-model of the uncontrolled system, the simulation model may be finished well
-before the controller for the entire system is finished.</p>
-</div>
-<div class="paragraph">
-<p>A problem arises when a controller that controls only part of the system, is
-merged with a simulation model of the entire uncontrolled system. In the
-uncontrolled system, the actuators can usually be turned on and off
-arbitrarily, as they are not yet controlled in any way. If the controller
-doesn’t control certain actuators, the behavior of those actuators is not
-restricted, and during simulation the events to turn the actuators on and off
-can happen at any time. Events are urgent, that is, they take precedence over
-passage of time, and thus happen 'immediately'. Events that are always enabled
-thus prevent passage of time. The simulation will turn the actuators on, off,
-on again, off again, etc.</p>
-</div>
-<div class="paragraph">
-<p>To solve this problem, the controllable events of the uncontrolled system that
-are not restricted in any way by the controller need to be disabled. The CIF
-event disabler tool makes this possible.</p>
-</div>
-<div class="paragraph">
-<p>This is however not the only usage scenario. The same controller may be used
-for implementation. For the implementation, a mapping from events to variables
-that represent the I/O ports may be needed. This mapping could be a CIF
-specification, with an automaton that performs the mapping. Similar to having
-a complete simulation model, a complete mapping specification for the
-implementation may be available. If in such mappings the actuator events are
-always enabled, this may lead to similar problems as for the simulation, if
-the controller only controls part of the system. Here too, the event disabler
-can be used to restrict such actuator events from causing trouble.</p>

-of the uncontrolled system that the controller may or may not restrict. That
-is, the <code>alphabet</code> (the second alternative in the above list) of controllable

-<div class="paragraph">
-<p>If the <em>Include input specification</em> option is enabled, the output
-specification is a copy of the input specification, which is then modified to
-disable certain events. For events that are disabled by the tool, but did not
-exist in the input specification, an event declaration is added. If the option
-is disabled, the output specification starts empty. For all events are
-disabled, an event declaration is added. Event declarations are added in
-their proper scopes, based on their absolute names, by adding groups around
-them as needed.</p>
-</div>
-<div class="paragraph">
-<p>
-
-By default, the <em>Include input specification</em> option is disabled. This ensures
-that the output specification is small. The typical scenario is to merge the
-input specification, event disabler output specification, and simulation model
-together using the <a href="#tools-chapter-mergecif">CIF merger</a> tool. Disabling the <em>Include input
-specification</em> specification option then gives the best performance for the
-tool chain.</p>
-</div>
-<div class="paragraph">
-<p>If any events are disabled by the tool, a new automaton is created, and this
-automaton is added to the output specification. The automaton is named
-<code>event_disabler</code>, but may be renamed if it conflicts with an already existing
-object with the same name. The automaton has no supervisory kind, and has the
-disabled events as alphabet. It has a single nameless location, with a single
-self loop for all of the events that are disabled. The guard of the self
-loop is <code>false</code>, which results in the events being globally disabled.</p>
-</div>
-<div class="paragraph">
-<p>If the <em>Include input specification</em> option is enabled, and events are disabled
-that did not exist in the input specification, event declarations are added to

-option is disabled, event declarations are added for all events that are
-disabled. Event declarations that are added and existed in the input
-specification (in case the <em>Include input specification</em> option is disabled),
-inherit their controllability from the input specification. All other events
-that are added are declared as controllable events if their name starts with

-<div class="sect3">
-<h4 id="tools-scripting-chapter-intro">Introduction to scripting</h4>
-<div class="paragraph">
-<p>All CIF <a href="#tools-chapter-index">tools</a> can be used in
-ToolDef scripts. ToolDef is a
-cross-platform and machine-independent scripting language that supports command
-line execution, but is also available as plug-in for
-<a href="https://eclipse.org">Eclipse</a>, providing an integrated development
-experience.</p>
-</div>
-<div class="sect4">
-<h5 id="tools-scenarios">Scenarios</h5>
-<div class="paragraph">
-<p>Using CIF tools in a ToolDef script can be useful for various reasons.</p>
-</div>
-<div class="paragraph">
-<p>Scripts allow executing multiple tools, one after the other, for instance to
-perform <a href="#tools-chapter-datasynth">data-based synthesis</a> on some sub-systems,
-<a href="#tools-chapter-mergecif">merge</a> the resulting supervisors, and
-<a href="#tools-cif2plc-chapter-index">generate PLC code</a> from it. Once a script is made,
-these steps can be easily repeated whenever the models for the sub-systems
-change. This is much easier than starting each of the tools manually, and saves
-valuable time. Furthermore, it is possible to share your script with others,
-who can then perform the same steps, and get the same results.</p>
-</div>
-<div class="paragraph">
-<p>A script can also be used to execute a single tool, specifying the parameters
-used when executing it. For instance, a script could execute the simulator,
-specifying not only which model (file) to simulate, but also the simulation
-options. If various <a href="#tools-cifsim-output-chapter-index">visualizations</a> are
-enabled, variables are <a href="#tools-cifsim-output-plotviz-filtering">filtered</a>,
-etc, manually configuring the options for each simulation can become tiresome.
-By specifying them in a script, simulating again with the same options becomes
-as simple as executing the script again. By sharing such a script with others,
-they can simulate the same model with the same options.</p>
-</div>
-<div class="paragraph">
-<p>Another use of scripts is to repeatedly execute the same tool, but with
-different parameters. A good example is
-<a href="#tools-cifsim-chapter-repeated-simulation">repeatedly simulating</a> a model.
-Instead of manually simulating a model with
-<a href="#tut-stochastics-chapter-intro">stochastics</a> hundreds or even thousands of
-times, which can be very time consuming, a script can be used to automate this
-task. The script can then also be used to automatically collect the results,
-and process them. Others can use the same script to repeat the experiments and
-verify the results, or to perform similar experiments.</p>
-</div>
-</div>
-<div class="sect4">
-<h5 id="tools-library-import">Library import</h5>
-<div class="paragraph">
-<p>In order to use CIF tools in a ToolDef script, the library with all CIF
-tools needs to be imported. The import statement to use is:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="tooldef">from "lib:cif" import *;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This statement imports all tools from the <code>cif</code> library, a library
-registered by the CIF tooling. You’ll want to include this import statement
-in all your own scripts that use CIF tools.</p>
-</div>
-</div>
-<div class="sect4">
-<h5 id="tools-execution-a-tool">Execution a tool</h5>
-<div class="paragraph">
-<p>Here is a simple example of a ToolDef script that simulates a model using the
-<a href="#tools-cifsim-chapter-index">CIF simulator</a>:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="tooldef">from "lib:cif" import *;
-
-cifsim("some_model.cif -i auto -t 10");</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The second statement executes the <code>cifsim</code> tool (the CIF simulator). This
-is just one of the tools that is available, but there are
-<a href="#tools-scripting-chapter-tools">many more</a>.</p>
-</div>
-</div>
-<div class="sect4">
-<h5 id="tools-command-line-arguments">Command line arguments</h5>
-<div class="paragraph">
-<p>Command line arguments can be used to let a tool know on which files it should
-operate, and what options it should use. The example above uses
-<code>"some_model.cif -i auto -t 10"</code> as arguments, consisting of the model to
-simulate (the <code>some_model.cif</code> file) and some simulation options
-(<a href="#tools-cifsim-input-chapter-automatic">automatic simulation</a> due to
-<code>-i auto</code>, and a simulation
-<a href="#tools-cifsim-termination-endtime">end time</a> of 10 time units due to
-<code>-t 10</code>).</p>
-</div>
-<div class="paragraph">
-<p>The command line options to use in ToolDef, are identical to the command line
-options to use for command line scripts, in a
-shell or command window. The CIF documentation generally refers to command line
-arguments or command line options, which can thus be used on the actual command
-line, as well as in ToolDef scripts.</p>
-</div>
-<div class="paragraph">
-<p>The command line arguments that are available are different for each tool. All
-CIF tools have <code>-h</code> and <code>--help</code> command line arguments that can be used
-to print the application help text to the console. The help text contains
-detailed information on all the command line arguments supported by the tool.
-Here is an example of how to show the help text for the simulator:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="tooldef">from "lib:cif" import *;
-
-cifsim("-h");</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>This information can also be seen in the option dialog:</p>
-</div>
-<div class="imageblock">
-<div class="content">
-<img src="./tools/scripting/option_dialog_cmdline_help.png" alt="option dialog cmdline help">
-</div>
-</div>
-<div class="paragraph">
-<p>The option dialog shows the same help text as the command line <code>--help</code> and
-<code>-h</code> options. In this screenshot, you can see the help text of the
-<code>--end-time</code> or <code>-t</code> option. This particular option can also be configured
-using the option dialog. It is part of the
-<b class="menuref">Simulator</b>
-category:</p>
-</div>
-<div class="imageblock">
-<div class="content">
-<img src="./tools/scripting/option_dialog_cmdline_link.png" alt="option dialog cmdline link">
-</div>
-</div>
-<div class="paragraph">
-<p>There, it is listed as
-<b class="menuref">Simulator end time</b>
-option. After that name,
-the command line names of the option (<code>--end-time</code> and <code>-t</code>) are also
-listed. This makes it easier to link options in the option dialog with command
-line options.</p>
-</div>
-<div class="paragraph">
-<p>In the example ToolDef scripts so far, all command line arguments are provided
-as a single string of text. However, it is also possible to provide each
-command line argument as a separate string. In fact, you may provide as many
-strings as you like, and each string may contain as many command line arguments
-as you like. For instance, the following statements each execute the simulator,
-and all have the same command line arguments, but provided in a different way:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="tooldef">cifsim("some_model.cif -i auto -t 10"); // Single string, all arguments.
-cifsim("some_model.cif", "-i auto", "-t 10"); // Multiple strings, multiple arguments each.
-cifsim("some_model.cif", "-i", "auto", "-t", "10"); // Multiple strings, one argument each.</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>For simulations, disabling a certain simulation option is a common task. By
-listing each simulation option on a separate line of the script, disabling or
-enabling a simulation option becomes as easy as commenting or uncommenting a
-line of the script. For instance, consider the following script:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="tooldef">from "lib:cif" import *;
-
-cifsim(
- "some_model.cif",
- "-i auto",
- "-t 10",
-);</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The model to simulate, the enabling of the automatic input mode, and the
-simulation end time, are each specified on a separate line. This makes it very
-easy to disable the simulation end time:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="tooldef">from "lib:cif" import *;
-
-cifsim(
- "some_model.cif",
- "-i auto",
- // "-t 10",
-);</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>To comment a line or multiple selected lines in a ToolDef text editor, use
-keyboard shortcut <span class="keyseq"><kbd>Ctrl</kbd>+<kbd>/</kbd></span> or the corresponding toolbar button
-(<span class="image"><img src="./tools/scripting/comment.png" alt="comment"></span>). For uncommenting, use keyboard shortcut

-<h5 id="tools-output-redirection-and-other-options">Output redirection and other options</h5>
-<div class="paragraph">
-<p>Besides the application specific options that can be configured using the

-<p>The command line arguments of the application. Each argument string is parsed

-all arguments (where the arguments themselves are separated by spaces), comma
-separated strings for each of the arguments (each string has one argument),
-or a mix of those.</p>
-<div class="paragraph">
-<p>In argument strings, individual arguments are separated by whitespace
-(spaces, tabs, new lines, etc). The whitespace itself is ignored, and only
-serves as separation. To include whitespace in an argument, the argument (or
-a part of it), may be quoted, by putting it between double quotes (<code>"</code>) or
-single quotes (<code>'</code>). Characters may be escaped by prefixing them with a
-backslash (<code>\</code>). This is particularly useful for single/double quotes, and
-escape characters, and can also be used to escape spaces. Escapes work the
-same inside of quoted parts as they do outside of quoted parts.</p>

-<div class="sect2">
-<h3 id="intro-chapter-chi">Chi</h3>
-<div class="paragraph">
-<p>The Chi language is a modeling language for describing and analyzing the
-performance of discrete event systems by means of simulation. The language
-design is based on decades of successful analyses of various (industrial)
-systems, aiming to be powerful for advanced users, and easy to use for
-non-experts.</p>
-</div>
-<div class="paragraph">
-<p>The language uses a process-based view. A system (and its control) is
-modeled as a collection of parallel running processes, communicating with
-each other using point-to-point communication channels. Processes do not
-share data with other processes, and channels are synchronous (sending and
-receiving is always done together at the same time), making reasoning about
-process behavior easier. Processes and channels are dynamic, new processes
-can be created as needed, and communication channels can be created or
-rerouted, making for a powerful specification language.</p>
-</div>
-<div class="paragraph">
-<p>The language is designed to be formal and easily extensible. Models are
-written as an imperative program, with an intuitive syntax, making it easy
-to read and write models. A small generic set of statements can be used to
-describe algorithms, including assignments, <em>if</em>, <em>while</em> and <em>for</em>
-statements. This set is relatively easy to explain to non-experts, allowing
-them to understand the model, and participate in the discussions.</p>
-</div>
-<div class="paragraph">
-<p>The data of the system can be modeled using both basic data types, such as
-<em>booleans</em> and <em>integer</em> and <em>real</em> numbers, as well as high level structured
-collections of data like <em>lists</em>, <em>sets</em> and <em>dictionaries</em>. If desired,
-processes and channels can also be part of that data. Furthermore, timers and
-(quasi-)random number generation distributions are available for modeling
-timed and stochastic systems. Features to easily specify repeated experiments,
-e.g. for stochastic simulation, or simulation for various inputs obtained
-from files, exist to support large simulation experiments.</p>
-</div>
-<div class="paragraph">
-<p>While the language is generic, the main application area is modeling of
-the operation of (manufacturing) systems. During the design process,
-engineers can make use of analytical models, to get answers about the
-operation of the system. Simulation studies can provide insights into
-e.g. the throughput of the system, the effect of set-up time in a
-machine, or how the batch size of an order will influence the flow time
-of the product-items.</p>
-</div>
-<div class="paragraph">
-<p>The Chi toolset allows verification of properties of the actual system by
-means of simulation, e.g. to optimize the supervisory (logic) control of
-the system. The Chi language has features that allow for easy
-specification of . Chi aims to make the process of verifying properties for large
-systems effortless.</p>
-</div>
-<div class="paragraph">
-<p>Tutorials and manuals demonstrate the use of the language for effective
-modeling of system processes. More detailed modeling of the processes and
-e.g performance indicators, or custom tailoring them to the real situation,
-has no inherent limits.</p>

-<div class="paragraph">
-<p>The CIF language is a powerful declarative automata-based modeling language for the
-specification of discrete event, timed (linear dynamics), hybrid (piecewise
-continuous dynamics) systems. It can be seen as a rich state machine language
-with the following main features:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Modular specification with synchronized events and communication between
-automata.</p>
-</li>
-<li>
-<p>Many data types are available (booleans, integers, reals, tuples, lists,
-arrays, sets, and dictionaries), combined with a powerful expression language
-for compact variables updates.</p>
-</li>
-<li>
-<p>Text-based specification of the automata, with many features to simplify
-modeling large non-trivial industrial systems.</p>
-</li>
-<li>
-<p>Primitives for supervisory controller synthesis are integrated in the
-language.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>The CIF tooling supports the entire development process of controllers,

-<div class="sect3">
-<h4 id="use-terminology-workspace">Eclipse workspace</h4>
-<div class="paragraph">
-<p>Eclipse stores all its settings in a so-called <em>workspace</em>. The workspace is
-simply a directory on your computer. You can choose any directory you like to
-serve as a workspace, as long as you have write access to that directory. It is
-usually best to choose an empty directory or a directory that does not yet
-exist as your workspace.</p>
-</div>
-<div class="paragraph">
-<p>Typically, and by default, a directory named <code>workspace</code> inside your Eclipse
-ESCET installation directory is used. Eclipse will ask you to choose a
-workspace directory when you start the Eclipse ESCET IDE for the
-<a href="#download-install-first-start">first time</a>.</p>
-</div>
-<div class="paragraph">
-<p>
-
-
-
-
-
-The actual settings are stored in a sub-directory of the workspace directory,
-called <code>.metadata</code>. You should avoid manually manipulating this directory.
-Note that because the name of the directory starts with a dot (<code>.</code>),
-depending on your operating system, file browser, and settings, the directory
-may be hidden.</p>
-</div>
-<div class="paragraph">
-<p>
-</p>
-</div>
-<div id="use-terminology-workspace-change" class="paragraph">
-<p>You can easily change your workspace directory from within Eclipse, by
-selecting <span class="menuseq"><b class="menu">File</b> <i class="fa fa-angle-right caret"></i> <b class="menuitem">Switch workspace</b></span>. Select one of the workspaces
-from the list of last used workspaces, or select <b class="menuref">Other…​</b> to freely
-select any directory on your system to use as a workspace directory.</p>
-</div>
-<div class="paragraph">
-<p>
-It is possible to run multiple instances of Eclipse at the same time, but each
-instance must use its own workspace.</p>
-</div>
-<div class="paragraph">
-<p>
-
-The workspace is also the default directory for
-<a href="#use-create-project">new projects</a>. However,
-<a href="#use-terminology-project">projects</a> don’t have to be physically located
-inside your workspace directory. They can be stored in any directory on
-your system. Whenever you <a href="#use-create-project">create a project</a> and store
-it outside of your workspace, or whenever you
-<a href="#use-import-project">import an existing project</a> from outside your
-workspace, it is <em>linked</em> to the workspace, but remains physically stored in
-a directory outside of the workspace.</p>
-</div>
-<div class="paragraph">
-<p>Having projects stored outside of the workspace has some benefits. The most

-</div>
-<div class="paragraph">
-<p>The Eclipse ESCET IDE and command line scripts run on
-<a href="https://en.wikipedia.org/wiki/Java_%28programming_language%29">Java</a>, a
-computer programming language. The <em>Java Virtual Machine</em> (JVM) manages all
-memory used by Eclipse, as well as the Eclipse ESCET tools. This page focuses
-on the Oracle JVM, as that is the JVM that we recommend. JVMs from other
-vendors may behave differently, and may have different settings. Also, new
-versions of the JVM often change/tweak their garbage collector, settings,
-defaults, etc. As such, the information on this page should be used to guide
-you, but may not be completely accurate.</p>
-</div>
-<div class="paragraph">
-<p>The JVM keeps track of all data that is maintained by the Eclipse ESCET tools,
-and releases (frees) the memory once it is no longer needed, so that it can
-be used to store other data. The JVM frees memory by means of a process called
-<a href="https://en.wikipedia.org/wiki/Garbage_collection_%28computer_science%29">garbage collection</a>
-(GC). Garbage collection is a complex process, but generally it consists of
-locking the memory to avoid modification during garbage collection, finding the
-data that is no longer used (mark the garbage), and then freeing the memory
-associated with that data (sweep the marked garbage).</p>

-overview of Java’s memory architecture, and the different types of memory that
-are used:</p>

-The operating system (OS) has memory available, either as physical
-<a href="https://en.wikipedia.org/wiki/Random-access_memory">RAM</a>, or
-as
-<a href="https://en.wikipedia.org/wiki/Virtual_memory">virtual memory</a>.
-When Java is executed, the Java program (<code>java</code> executable on Linux and macOS,
-<code>java.exe</code> on Windows), becomes one of the running
-<a href="https://en.wikipedia.org/wiki/Process_%28computing%29">processes</a>. The
-process uses a part of the operating system’s memory to store its data. This
-memory is called the <em>Java process heap</em>. The <em>Java process heap</em> is divided
-into two parts, the <em>Java object heap</em> and <em>'Everything else'</em>. The
-<em>Java object heap</em> contains all data actually used by the running Java program,
-which in our case is the Eclipse ESCET IDE and/or Eclipse ESCET command line
-scripts. The <em>'Everything else'</em> part contains various data, mostly used by
-the JVM internally.</p>
-</div>
-<div class="paragraph">
-<p>
-

-
-Java uses a generational garbage collector. New data, called <em>objects</em> in Java,
-are created in the <em>young generation</em>, or more specifically, in its
-<em>allocation space</em> (also called <em>eden space</em>). When the young generation
-becomes full, the garbage collector will remove all garbage (no longer used
-data) using a <em>minor collection</em>, which removes garbage from the young
-generation. The garbage collector uses the survivor spaces to store the
-surviving objects. Objects that survive a few minor collections are moved to
-the <em>old generation</em>, which stores the longer living objects, as well as the
-larger objects that don’t fit in the young generation, which is usually much
-smaller than the old generation. When the old generation becomes full, the
-garbage collector performs a <em>major collection</em> removing garbage from the
-entire Java object heap, which is much more work, and thus much more costly
-than a minor collection.</p>
-</div>
-<div class="paragraph">
-<p>The <em>'Everything else'</em> part of the Java process heap contains various data
-used internally by the JVM. This includes the <em>'Metaspace'</em> with all the Java
-code of Eclipse and our own plugins, the values of constants, etc. It also
-includes the <em>native code</em>, the highly optimized code generated for the
-specific
-<a href="https://en.wikipedia.org/wiki/Computer_architecture">architecture</a>
-of your machine, that can actually be executed on your processor. Furthermore,
-it includes the
-<a href="https://en.wikipedia.org/wiki/Stack-based_memory_allocation">stacks</a>
-of all the
-<a href="https://en.wikipedia.org/wiki/Thread_%28computer_science%29">threads</a>
-that are running in parallel. There is also a part that contains the data
-maintained by the garbage collector itself, for administrative purposes. The
-'Everything else' part contains various other types of data, that are
-irrelevant for the current discussion.</p>

-<h4 id="performance-tweak-perf-settings-benefits">Benefits of increasing the available memory</h4>
-<div class="paragraph">
-<p>If Java runs out of available memory, our applications running in Eclipse will
-terminate with an 'out of memory' error message. In such cases, increasing the
-available memory will likely solve the problem. However, even if you don’t run
-out of memory, increasing the amount of memory that is available to Java can
-significantly improve Java’s performance.</p>
-</div>
-<div class="paragraph">
-<p>The garbage collector performs a minor collection when the young generation
-becomes 'full'. Here, 'full' doesn’t necessarily mean 100%, as Java by default
-tries to keep the heap about 40% to 70% filled. Increasing the size of the
-young generation makes it possible to allocate more new objects before the
-young generation becomes 'full'. During garbage collection, program execution
-may become halted, to ensure that memory doesn’t change during the collection
-process. The longer one can go without garbage collection, the less halting,
-and thus the greater the performance of the program.</p>
-</div>
-<div class="paragraph">
-<p>
-
-If an application uses a lot of data that lives for longer periods of time, the
-old generation may become mostly filled with data. It then becomes harder and
-harder for the garbage collector to move objects from the young generation to
-the old generation. This may be caused by
-<a href="https://en.wikipedia.org/wiki/Fragmentation_%28computing%29">fragmentation</a>,
-due to some objects from the old generation being removed by the garbage
-collector. In such cases, if the <em>gaps</em> are too small to hold the new objects,
-the old generation may need to be <em>compacted</em>, a form of
-<a href="https://en.wikipedia.org/wiki/Defragmentation">defragmentation</a>. After
-compaction, the single larger gap hopefully has more than enough free space to
-contain the new objects. The compaction process is expensive, as a lot of
-objects need to moved. If the situation gets really bad, Java may need to spend
-more time performing expensive garbage collection operations than it spends
-time on actually executing the program you’re running. By increasing the size
-of the old generation to more than the application needs, a lot more free space
-is available, reducing the need for frequent compaction, thus significantly
-increasing the performance of the application.</p>
-</div>
-<div class="paragraph">
-<p>These are just some of the reasons why increasing the amount of available
-memory can improve program execution times, even though enough memory was
-already available to complete the given task. In general, the more memory
-Java has, the better it performs.</p>

-<div class="paragraph">
-<p>There are several ways to supply the command line arguments for the settings to
-Java. The easiest way to do it, when using Eclipse, is to modify the
-<code>eclipse.ini</code> file. By default, it is located in your Eclipse
-ESCET installation directory, except for macOS, where instead it is in the
-<code>Eclipse.app/Contents/MacOS</code> directory inside the Eclipse ESCET installation
-directory.</p>
-</div>
-<div class="paragraph">
-<p>Each of the settings you want to change should be added to the <code>eclipse.ini</code>
-text file, in the command line syntax. Each setting must be put on a line
-<em>by itself</em>. Furthermore, all these JVM settings must be put <em>after</em> the line
-that contains <code>-vmargs</code>. Settings on lines before the <code>-vmargs</code> line are the
-settings for the launcher that starts Eclipse, and should <em>not</em> be changed.</p>
-</div>
-<div class="paragraph">
-<p>Note that the default <code>eclipse.ini</code> file supplied with Eclipse may already
-contain some of the settings. If so, don’t add the setting again. Instead,
-change the value of the existing setting. The settings that are present by
-default, as well as their values, may change from release to release.</p>
-</div>
-<div class="paragraph">
-<p>After modifying <code>eclipse.ini</code>, restart the Eclipse ESCET IDE or command line
-script for the changes to take effect.</p>

-<div class="paragraph">
-<p>Using the <code>-vmargs</code> command line option replaces the similar settings from

-In general, giving Java extra memory only makes it perform better. As such,

-idea, if you have enough free memory.</p>
-</div>
-<div class="paragraph">
-<p>
-If you actually run out of memory, Java will emit a
-<code>java.lang.OutOfMemoryError</code>, with a message to indicate the type of memory
-that was insufficient. Below the most common out of memory error message are
-listed, with possible solutions:</p>

-is to make sure the limit is not exceeded, by giving Java more memory, and
-thus making it easier for the garbage collector to do its work. Increase the
-maximum Java object heap size (<code>-Xmx</code> setting).</p>
-</div>
-<div class="paragraph">
-<p>Alternatively, disable the 'use garbage collector overhead limit' feature
-(<code>-XX:-UseGCOverheadLimit</code> setting, note the <code>-</code> instead of the <code>+</code>).

-<p>Giving the JVM too much memory (especially via the <code>-Xmx</code> setting), can make
-the JVM fail to start, or crash
-shortly after starting. This problem mostly applies to 32-bit JVMs. The JVM
-needs to reserve a contiguous region of memory, or rather a contiguous region
-of the
-<a href="https://en.wikipedia.org/wiki/Address_space">address space</a>. On 32-bit
-JVMs, at most 4 GB of space can be addressed, of which a part is already in use
-by the operating system, drivers, and other applications. Thus, requesting too
-much memory, even if it is available, may cause problems, if no contiguous
-region of address space of that size is available when starting the JVM. If you
-request too much memory, you may get a <code>Invalid maximum heap size: -Xmx****m
-The specified size exceeds the maximum representable size. Could not create the
-Java virtual machine.</code> or <code>Error occurred during initialization of VM Could
-not reserve enough space for object heap</code> error when starting the JVM. For

-<p>The GitFlow branching model allows for sub teams that share work but don’t
-push that to 'origin' (yet). It also allows feature branches that live only
-locally on a developer’s PC and not on 'origin'. To be transparent, Eclipse
-Foundation open source projects don’t do this. We push to our GitLab server
-regularly, to ensure that the community can see what the project is working on.</p>
-</li>
-<li>
-<p>We have no strict branch naming rules. You can Let GitLab create the branch
-for the issue. For an issue with number #2 named 'Test', it will create a
-branch named <code>2-test</code>. This includes the issue number, which makes it easy to
-relate a branch to an issue, without having to look inside the branch for
-commits (if there even are any). It also includes the issue name, which is
-convenient as it indicates what the branch is about, without having to look
-up the issue.</p>

-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>The top layer contains user-oriented languages for designing controllers.
-Currently there are two modeling languages in this layer,
-<a href="#intro-chapter-cif">CIF</a> and <a href="#intro-chapter-chi">Chi</a>.</p>
-<div class="paragraph">
-<p>The third language in the top layer is <a href="#intro-chapter-tooldef">ToolDef</a>, a
-cross-platform scripting language to run tests, and to automate the various
-tools that need to be executed while designing a controller.</p>
-</div>
-</li>
-<li>
-<p>The middle layer contains developer oriented support code.
-It has a language of its own, named <a href="#intro-chapter-setext">SeText</a>. This
-language implements an LALR(1) parser generator with a few twists to make it
-easy to use in a Java environment and to connect it to an Eclipse text editor.</p>
-<div class="paragraph">
-<p>The other part of the middle layer is common functionality shared between the
-languages.</p>
-</div>
-</li>
-<li>
-<p>The bottom layer is mostly configuration to attach the software to the Eclipse
-platform, including build and release engineering.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>This document describes the structure of the top and middle layers. For the
-bottom layer, standard Eclipse and Maven/Tycho tools are used, which are
-described elsewhere.</p>
-</div>
-<div class="paragraph">
-<p>The three layers are not further distinguished in the repository. Instead,
-different parts are stored in different sub-directories from the root.</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="developer-language-directories">Language directories</h4>
-<div class="paragraph">
-<p>Each language has its own subdirectory in the root, <code>/cif</code> and <code>/chi</code> for the

-<code>/tooldef</code> for the <a href="#intro-chapter-tooldef">ToolDef</a> language,
-and <code>/setext</code> for the <a href="#intro-chapter-setext">SeText</a> language.</p>
-</div>
-<div class="paragraph">
-<p>Within a language directory, a directory exists for each part of the code
-(often equivalent to a plugin), with the same name as the plugin.
-The pattern of a plugin name is <code>org.eclipse.escet.<language>.<plugin-name></code>

-<h3 id="app-framework-introduction">Introduction</h3>
-<div class="paragraph">
-<p>The Eclipse ESCET application framework provides common functionality for
-applications within the Eclipse ESCET toolkit. It has several goals:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Provide a uniform end-user experience, for example in the form of uniform
-option dialogs.</p>
-</li>
-<li>
-<p>Hide technical details from the end user, for example in the form of
-crash reports and user friendly error messages, instead of stack traces.</p>
-</li>
-<li>
-<p>Provide support for applications to run both as a stand-alone Java program
-(say, from the command line), as well as within the Eclipse environment.</p>
-</li>
-<li>
-<p>Provide the basic functionality needed by most applications, to reduce the
-overhead needed for developers to develop an application.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>The documentation for this framework describes the issues that the application
-framework attempts to solve, and the way it solves them. It also provides
-guidance in implementing applications using the application framework.</p>
-</div>
-<div class="paragraph">
-<p>
-</p>
-</div>
-</div>
-<div class="sect2">
-<h3 id="app-framework-standalone-vs-eclipse">Stand-alone execution versus Eclipse IDE</h3>
-<div class="paragraph">
-<p>One of the goals of the application framework is to make it easier to allow
-applications to run as stand-alone Java command line applications, as well as
-run within the Eclipse IDE. The main problem faced when
-supporting general applications to run within Eclipse, is that such
-applications all run within the same instance of the Java Virtual Machine
-(JVM). In fact, a single application may have multiple instances running at
-the same time, within a single instance of the IDE. The following sections
-address the issues that arise when running within the IDE, and how the
-application framework handles them.</p>
-</div>
-<div class="paragraph">
-<p></p>
-</div>
-<div class="sect3">
-<h4 id="app-framework-app-static-information">Application static information</h4>
-<div class="paragraph">
-<p>Within Java programs, members can be defined with the <code>static</code> modifier.
-Since multiple instances of an application may be running simultaneously,
-within a single instance of the IDE, one should avoid using static variables
-that contain information that is specific to a single instance of the
-application. For instance, assume an application that maintains an integer
-counter, used to generate unique identifiers. If defined in a class as
-follows:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="java"><span class="directive">public</span> <span class="directive">static</span> <span class="type">int</span> count = <span class="integer">0</span>;</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>and incremented when needed, the first instance of the application will run
-just fine. Variable <code>count</code> starts at zero, and is incremented over and over
-again. When a second instance of the application starts however, the static
-variable keeps its value, as the new application is started within the same
-Eclipse instance, and thus within the same JVM. The count won’t start from
-zero, thus leading to different results for the application.</p>
-</div>
-<div class="paragraph">
-<p>The conclusion is that one should be careful to avoid static variables that
-hold information specific to an application instance.</p>
-</div>
-<div class="paragraph">
-<p></p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="app-framework-application-options">Application options</h4>
-<div class="paragraph">
-<p>Applications often have settings, and they are generally passed as command
-line arguments. GUI applications however, often use a dialog to configure the
-options instead. To allow applications within the application framework to
-work in both scenarios, all applications should use the option framework.</p>
-</div>
-<div class="paragraph">
-<p>See also the <a href="#app-framework-option-framework">option framework</a> section.</p>
-</div>
-<div class="paragraph">
-<p>
-
-</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="app-framework-stdin-stdout-stderr">Stdin, stdout, and stderr</h4>
-<div class="paragraph">
-<p>Command line applications generally obtain input from stdin, and write output
-to stdout and/or stderr streams. For applications running within the IDE,
-those streams are connected to the Eclipse application (IDE) as a whole, and
-not to the applications running within the IDE. To provide a uniform I/O
-interface, the application framework includes an I/O framework.</p>
-</div>
-<div class="paragraph">
-<p>See also the <a href="#app-framework-io-framework">I/O framework</a> section.</p>
-</div>
-<div class="paragraph">
-<p>
-</p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="app-framework-guis-and-swt">Graphical User Interfaces (GUIs) and SWT</h4>
-<div class="paragraph">
-<p>The Eclipse IDE uses the Standard Widget Toolkit (SWT) for its graphical user interface
-(GUI). To be compatible with the Eclipse IDE, all GUI applications should use SWT as
-well. In order for GUI applications to work seamlessly within the Eclipse IDE as well
-as stand-alone, the application framework automatically registers the main SWT
-display thread for stand-alone applications, and uses the Eclipse SWT display
-thread when running within the Eclipse IDE. This reduces the burden of having to
-register the main SWT display threads, but also avoids blocking and other thread
-related issues.</p>
-</div>
-<div class="paragraph">
-<p>Using the <em>GUI</em> option, the GUI can be enabled or disabled. If disabled,
-headless execution mode is used, which disables creation of a SWT display
-thread, and thus disables all GUI functionality, including the option dialog.</p>
-</div>
-<div class="paragraph">
-<p></p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="app-framework-app-termination">Application termination</h4>
-<div class="paragraph">
-<p>Within Java, the <code>System.exit</code> method can be used to immediately terminate
-an application, by terminating the JVM. For applications running within
-the Eclipse IDE, this not only terminates the application, but the IDE as well. As
-such, the <code>System.exit</code> method should never be used in applications that
-are intended to be executed within the IDE.</p>
-</div>
-<div class="paragraph">
-<p></p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="app-framework-sigint">SIGINT</h4>
-<div class="paragraph">
-<p>Stand-alone applications can typically be started from a the command line
-terminal window. Pressing <span class="keyseq"><kbd>Ctrl</kbd>+<kbd>C</kbd></span> at such a command line terminal window
-terminates the currently running application (on Unix-based systems, this
-generates a SIGINT). Applications running within the Eclipse IDE however, don’t run
-in an actual command line terminal. Instead, they run within the IDE,
-and the stdin, stdout, and stderr streams are coupled to the Eclipse console
-view. The Eclipse console view does not support termination using the
-<span class="keyseq"><kbd>Ctrl</kbd>+<kbd>C</kbd></span> key combination. Instead, <span class="keyseq"><kbd>Ctrl</kbd>+<kbd>C</kbd></span> is used to copy console output
-to the clipboard. To remedy this situation, application framework applications
-running within Eclipse get a <em>Terminate</em> button with their console within the IDE,
-to allow for easy termination.</p>
-</div>

-<p>Exceptions are Java feature that allows applications to report error
-conditions. Exceptions can generally be divided into two categories: internal
-errors, and end-user errors. Internal errors should generally not happen,
-and make the application crash. The application framework provides crash
-reports for end users to report crashes due to internal errors. The application
-framework also provides exception classes for end-user errors, to provide
-nice error messages, instead of stack traces.</p>

-<div class="paragraph">
-<p>Java uses system properties (<code>System.getProperty</code> method etc). Those
-properties are global to the entire JVM, meaning they are shared between
-applications running within the Eclipse IDE. The application framework provides
-functionality to maintain system properties on a per application basis,
-turning them into application properties. All application framework
-applications should use the <code>getProp*</code> and <code>setProp*</code> methods in the
-<code>AppEnv</code> class instead of the property related methods in the <code>System</code>
-class. This ensures that the application properties are used instead of the
-global system properties.</p>

-<h4 id="app-framework-filepaths-and-current-working-dir">File paths and current working directory</h4>
-<div class="paragraph">
-<p>One of the standard system properties in Java is the <code>user.dir</code> property,
-which refers to the current working directory, or more precisely, the
-directory from which the JVM was started. Java doesn’t allow changing
-the current working directory. The application framework however, maintains
-the current working directory on a per application basis. Changing the current
-working directory is also supported. Application framework applications
-should use the methods in the <code>org.eclipse.escet.common.app.framework.Paths</code>
-class to get and set the current working directory, to resolve relative paths,
-etc. These methods also allow both Windows (<code>\</code>) and Unix (<code>/</code>) separators to
-be used in paths, on all platforms, transparently.</p>
-</div>
-<div class="paragraph">
-<p>Furthermore, within the Eclipse IDE, the concept of a
-<a href="#use-terminology-workspace">workspace</a> is introduced. In
-order to allow importing of resources from other projects etc, it may be nice
-to allow end users to specify platform paths (plug-in paths or workspace
-paths). Eclipse Modeling Framework (EMF) URIs, besides local file system paths,
-provide functionality for platform URIs as well. EMF URIs can for instance be
-used to load models that are instances of an Ecore. The <code>Paths</code> class mentioned
-above features methods to create such EMF URIs, from various sources. Those
-methods also feature smart handling of <code>platform:/auto/...</code> paths, an addition to
-platform URIs, added by the application framework. Such URIs are first
-resolved in the workspace, and if they can’t be found there, they are resolved
-in the plug-ins. This allows for easier debugging, as the workspace always
-overrides the plug-ins.</p>

-<p>The I/O framework works with output components. All output that the application
-generates, is given to the output components. Each output component can decide
-for itself what to do with that output. All applications include at least
-a <code>StreamOutputComponent</code>, that redirects stream output to the console. For
-stand-alone applications, this means redirection to stdout and stderr. For
-application running within the Eclipse IDE, this means redirection to a
-<em>Console</em> <a href="#use-terminology-view">view</a>.</p>
-</div>
-<div class="paragraph">
-<p>Applications that only need to provide error, warning, normal, and debug
-textual output, the default output component interface (<code>IOutputComponent</code>)

-create a derived interface that inherits from <code>IOutputComponent</code>, and extends

-<h4 id="app-framework-runinternal-method">The runInternal method</h4>
-<div class="paragraph">
-<p>Some things to consider when implementing the <code>runInternal</code> method:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>If you want to support stand-alone execution, register all Eclipse Modeling
-Framework (EMF) metamodels with the EMF metamodel registry. Also register any
-parsers, constraints, etc. For instance:</p>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="java"><span class="keyword">if</span> (!Platform.isRunning()) {
- <span class="comment">// Register languages and parsers for stand-alone execution.</span>
- LanguageRegistry.register...(...)
-}</code></pre>
-</div>
-</div>
-</li>
-<li>
-<p>The start of the <code>runInternal</code> method is a good place to add output
-components, as all options have been fully processed at this point. Output
-components can be registered by using the application’s output provider
-(though static methods).</p>
-</li>
-<li>
-<p>The code in this method and all code directly or indirectly executed by this
-method, should regularly call the <code>AppEnv.isTerminationRequested</code> method,
-to find out whether the application should be terminated.</p>
-</li>
-<li>
-<p>For the return code of this method, always use value zero, to indicate
-successful termination. Other exit codes are automatically generated by the
-exception framework, if applicable. See also the
-<a href="#app-framework-exit-codes">exit codes</a> section.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">

-</div>
-</div>
-<div class="sect2">
-<h3 id="app-framework-registration">Application registration</h3>
-<div class="paragraph">
-<p>Applications that use the application framework maintain their own data. This
-includes options, output components (via an output provider), streams, etc.
-Only a single application can be registered for each thread. Only once the
-application terminates and automatically unregisters itself, can a new
-application register itself in that thread. To run multiple applications
-in parallel, simply run them on different threads.</p>
-</div>
-<div class="paragraph">
-<p>
-</p>
-</div>
-<div class="sect3">
-<h4 id="app-framework-multi-threaded-apps">Multi-threaded applications</h4>
-<div class="paragraph">
-<p>All data stored for the application is wrapped in the <code>AppEnvData</code> class, and
-stored by the <code>AppEnv</code> class, on a per-thread basis. If your application uses
-multiple threads, you need to register each thread with the application
-framework. Use the <code>AppEnv.registerThread</code> method for this. This method
-requires the current application environment data as parameter, which may
-be obtained by using the <code>AppEnv.getData</code> method. To avoid managed memory
-leaks, always unregister threads once they are no longer used, by using the
-<code>AppEnv.unregisterThread</code> method.</p>
-</div>
-<div class="paragraph">
-<p></p>
-</div>
-</div>
-<div class="sect3">
-<h4 id="app-framework-unit-tests">Unit tests</h4>
-<div class="paragraph">
-<p>If unit tests use methods that depend on the application being registered, then
-the unit test will need to register an application. Examples of method using
-the application framework are methods that use options, or produce output via
-the application framework. Especially for unit tests, the
-<code>AppEnv.registerSimple</code> method can be used to register a dummy application.
-This method uses a default application environment, without an actual
-application, registers a default stream output provider, sets the output mode
-to errors and warnings only (no normal or debug output), and disables
-development mode. It can be used in a unit test class as follows:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="java"><span class="comment">/***/</span> <span class="annotation">@BeforeClass</span>
-<span class="directive">public</span> <span class="directive">static</span> <span class="type">void</span> oneTimeSetUp() {
- AppEnv.registerSimple();

-<span class="directive">public</span> <span class="directive">static</span> <span class="type">void</span> oneTimeTearDown() {
- AppEnv.unregisterApplication();
-}</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>If any options are used, they will need to be available as well. For instance,
-one could add the following to the <code>oneTimeSetUp</code> method, or at the start of
-the actual unit test method:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="java">Options.set(SomeOption.class, <value>);</code></pre>

-<div class="sect3">
-<h4 id="app-framework-running-app-from-other-app">Running an application from another application</h4>
-<div class="paragraph">
-<p>As noted above, only a single application can be registered for a single
-thread. To start one application from another application, simply run the
-second application in a fresh thread. In the new thread, do the following:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Construct the child application, using a constructor with the <code>AppStreams</code>
-argument, to pass along the streams from the parent application.</p>
-</li>
-<li>
-<p>Set the current working directory to the current working directory of the
-parent application.</p>
-</li>
-<li>
-<p>Obtain the Eclipse IDE console (if any) from the parent application, and couple
-it the child application.</p>
-</li>
-<li>
-<p>Run the child application.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>After the child application thread finishes, make sure you:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Restore the coupling between the Eclipse IDE console (if any) and the parent
-application.</p>
-</li>
-<li>
-<p>If the child application finished due to a termination request, request
-termination for the parent application.</p>
-</li>
-<li>
-<p>Decide what to do with the exit code of the child application. If it is
-non-zero, you’ll probably want to terminate the parent application.</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>To make it easier to follow this approach, the <code>ChildAppStarter.exec</code>
-methods can be used.</p>

-<p>Terminals can be specified as follows:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="setext">@terminals:
- @keywords Operators = and or;
- @keywords Functions = log sin cos tan;
-end
-
-@terminals:
- IDTK = "$?[a-zA-Z_][a-zA-Z0-9_]*" {scanID};
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Here we specified two groups of terminals. The first group specifies two
-keyword (sub-)groups, named <code>Operators</code> and <code>Functions</code>. For these keywords
-(<code>and</code>, <code>or</code>, <code>log</code>, etc), terminals are created (<code>ANDKW</code>, <code>ORKW</code>,
-<code>LOGKW</code>, etc). Furthermore, the keyword group names (<code>Operators</code> and
-<code>Functions</code>) may be used as non-terminals in the grammar, to recognize
-exactly one of the keyword terminals created for that keyword group.</p>
-</div>
-<div class="paragraph">
-<p>The second group specifies an <code>IDTK</code> terminal, defined by a regular
-expression (see below). The <code>{scanID}</code> part indicates that the resulting
-tokens should be passed to the <code>scanID</code> method in the hooks class (see
-below), to allow post-processing. Post-processing methods are also allowed
-for keyword identifiers, such as <code>sin</code> and <code>cos</code> in the example.</p>
-</div>
-<div class="paragraph">
-<p>SeText generated scanners use longest match when recognizing tokens. If two
-or more terminals recognize the same longest match, priorities are used to
-resolve the conflict. For the example above, the first group of terminals has
-priority over the second group, thus giving the keywords priority over the
-identifiers. That is, <code>@terminals</code> groups listed earlier in the specification
-have higher priority than <code>@terminals</code> groups listed later in the
-specification. If two terminals accept the same input, and they are defined
-within the same group (they have the same priority), then the specification
-is invalid.</p>
-</div>
-<div class="paragraph">
-<p>It is also possible to use scanner states:</p>

-
-@terminals BLOCK_COMMENT:
- "\*/" ->;
- ".";
- "\n";
-end</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>The first group of terminals is for the default state, as no state name is
-specified. Single line comments (<code>// ...</code>) are detected using the first
-regular expression. This expression is not given a name, and can thus not be
-used in parser rules.</p>
-</div>
-<div class="paragraph">
-<p>The second regular expression detects the start of block comments (<code>/*</code>)
-and switches the scanner to the <code>BLOCK_COMMENT</code> state.</p>
-</div>
-<div class="paragraph">
-<p>The second group of terminals is detected only when the scanner is in the
-<code>BLOCK_COMMENT</code> state, as indicated by the <code>BLOCK_COMMENT</code> state name after
-the <code>@terminals</code> keyword. Everything except for the end of the comment is
-ignored (no name for the terminals, and no new scanner state). The end of
-block comments (<code>*/</code>) makes the scanner go back to the default scanner
-state (arrow without state name).</p>
-</div>
-<div class="paragraph">
-<p>The <code>@eof</code> terminal indicates that end-of-file is allowed in a scanner
-state (in this case, the default scanner state).</p>
-</div>
-<div class="paragraph">
-<p>For every scanner, the name of the Java class to generate should be specified,

-<p>The scanner class must not be a generic class. Imports (see below) can be used

-</li>
-<li>
-<p><code>[a-z]</code> for exactly one of the characters <code>a</code>, <code>b</code>, …​, or <code>z</code>.
-This notation is called a character class. Note that the ranges of
-characters are based on their ASCII character codes.</p>
-</li>
-<li>
-<p><code>[^a]</code> for any ASCII character except for character <code>a</code>. This notation
-is called a negated character class.</p>
-</li>

-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>To include special characters, they must always be escaped, wherever they
-occur in the regular expression. For instance, regular expression <code>[a\^]</code>
-recognizes either character <code>a</code> or character <code>^</code> (but not both). Here
-the <code>^</code> character is escaped, as it is a special character (it may be used
-at the beginning of a character class to invert the character class).</p>
-</div>
-<div class="paragraph">
-<p>New lines are not allowed in the regular expressions themselves. Obviously,
-it is possible to detect new lines using regular expressions.</p>

-<div class="sect1">
-<h2 id="setext-readme-terminal-descriptions">Terminal descriptions</h2>
-<div class="sectionbody">
-<div class="paragraph">
-<p>Terminals can be given an end user readable description (just before the

- "[def]"; // no description</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>Keyword literals (<code>ANDTK</code> and <code>ORTK</code> in the example above) have the
-keywords surrounded by double quotes as default description. Similarly,
-terminals defined by regular expressions without choice (no character classes,
-star operators, etc) and using only 'graphical' characters (no control
-characters, end-of-file, new lines, etc) also have the literal text that they
-match (surrounded by double quotes) as default description (see <code>ASGNTK</code> in
-the example above). The end-of-file token has <code>end-of-file</code> as default
-description. Keywords that don’t have a description and don’t have default
-descriptions as described above, get the name of the terminal as description
-(see <code>X</code> in the example above). If they don’t have a name, they have no
-description.</p>
-</div>
-<div class="paragraph">
-<p>Nameless terminals are not used by the parser, and therefore do not require a
-description. The end-of-file terminal has a default description, and can not be
-given a custom description. Giving a terminal a custom description if it
-already has a default description, leads to a warning.</p>

-<div class="sectionbody">
-<div class="paragraph">
-<p>Here are some hints on using SeText:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>It is recommended to name the generated and hooks classes, using the
-following convention: <code>XyzScanner</code>, <code>XyzParser</code>, <code>XyzHooks</code>, for
-the scanner, parser, and hooks classes of a language <code>Xyz</code> or <code>XYZ</code>.
-For parsers for a part of a language, it is recommended to name the
-generated parsers <code>XyzPartParser</code>, for non-terminal <code>Part</code> of language
-<code>Xyz</code> or <code>XYZ</code>. Following these naming conventions ensures consistency
-in the naming of the classes.</p>
-</li>
-<li>
-<p>It is recommended to import the packages that contain the classes used
-as the types of the non-terminals. For instance, import the expressions
-package <code>some.long.package.name.expressions</code> as <code>expressions</code> or
-<code>exprs</code>, and then use <code>{exprs.SomeClass}</code> as the type for a
-non-terminal, instead of <code>{some.long.package.name.expressions.SomeClass}</code>.
-Importing the package instead of the individual classes reduces the number
-of imports, and also avoids conflicts between non-terminals names and
-class names. For standard Java types, however, it is recommended to import
-the full type. For instance, import <code>java.lang.String</code> or
-<code>java.util.List</code>.</p>
-</li>
-</ul>
-</div>
-</div>
-</div>
-<div class="sect1">
-<h2 id="setext-readme-generated-scanners-parsers">Generated scanners/parsers</h2>
-<div class="sectionbody">
-<div class="paragraph">
-<p>The generated scanners and parsers depend on the <code>org.eclipse.escet.setext.runtime</code>
-and <code>org.eclipse.escet.common.java</code> plug-ins. Generated scanners and parsers inherit
-from the <code>org.eclipse.escet.setext.runtime.Scanner</code> class and
-<code>org.eclipse.escet.setext.runtime.Parser</code> class respectively. Look at those classes for
-the public API of generated scanners/parsers, as it should be fairly
-self-explanatory.</p>
-</div>
-<div class="paragraph">
-<p>Besides the scanner and parser(s), debug output is generated from which the
-scanner and parser(s) can be analyzed. In particular, the debug output for
-the parsers makes it possible to find out the details about conflicts in the
-grammar. Furthermore, a skeleton is generated for the hooks class.</p>

-<h2 id="setext-readme-using-in-an-eclipse-plugin-project">Using SeText in an Eclipse Plug-in Project</h2>
-<div class="sectionbody">
-<div class="paragraph">
-<p>For a new language, follow these steps:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Create a <em>Plug-in Project</em> in Eclipse.</p>
-</li>
-<li>
-<p>Add the <code>org.eclipse.escet.common.java</code> and <code>org.eclipse.escet.setext.runtime</code> plug-ins to
-the <em>Required plug-ins</em> in the project’s manifest. Also add any plug-ins
-that define the classes that you will be referring to in the SeText
-specification.</p>
-</li>
-<li>
-<p>Create the Java package where your scanner, parser(s) and hooks classes
-are to be stored.</p>
-</li>
-<li>
-<p>Create a text file ending with <code>.setext</code> in that same package. Fill the
-specification, and save it.</p>
-</li>
-<li>
-<p>Right click the file in the <em>Project Explorer</em> or <em>Package Explorer</em>,
-and choose the <em>Generate Parser(s)</em> action. Alternatively, right click
-the text editor for the SeText specification and choose the same action.</p>
-</li>
-<li>
-<p>Observe how the files are generated. Make sure the console is free of
-warnings and errors.</p>
-</li>
-<li>
-<p>Copy the hooks class skeleton (extension <code>.skeleton</code> to extension
-<code>.java</code>), and implement the hooks.</p>
-</li>
-<li>
-<p>You are ready to use the scanner and parser(s).</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>After changes to the SeText specification:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Regenerate the code, as before.</p>
-</li>
-<li>
-<p>If a <code>Hooks</code> interface has changed, update the hooks class.</p>
-</li>
-<li>
-<p>You are ready to use the modified scanner and parser(s).</p>
-</li>
-</ul>
-</div>
-<div class="paragraph">
-<p>It may be a good idea to put the <code>.skeleton</code> file in a version control
-system. That way, after regeneration, you can ask for a diff. You then
-know what has changed, and how you need to update the hooks class.</p>
-</div>
-<div class="paragraph">
-<p>Also note that if a generated <code>Hooks</code> interface changes after a regeneration,
-Java will report errors for methods not yet present in the hook class.
-Similarly, Java will complain about changed method signatures, and methods that
-no longer exist in the <code>Hooks</code> interface (and thus have invalid <code>@Override</code>
-annotations in the hooks class).</p>

-<div class="sectionbody">
-<div class="paragraph">
-<p>The following limitations currently apply:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>SeText only allows for the specification of scanners that accept ASCII
-input.</p>
-</li>
-<li>
-<p>SeText currently assumes UTF-8 encoded files. If the input file is actually
-encoded using a different encoding, scanner exceptions may indicate the
-wrong character.</p>

-<p>The ToolDef language features the following concepts:</p>
-</div>
-<div class="ulist">
-<ul>
-<li>
-<p>Simple and intuitive syntax makes it easy to writing scripts.</p>
-</li>
-<li>
-<p>A large number of built-in data types, including booleans, integers, longs,
-doubles, strings, lists, sets, maps, tuples, and objects.</p>
-</li>
-<li>
-<p>Static typing allows to catch simple mistakes.</p>
-</li>
-<li>
-<p>The type system is compatible with <a href="http://oracle.com/java">Java</a>,
-allowing easy integration with existing Java code.</p>
-</li>
-<li>
-<p>A large library of useful built-in operators and tools, including tools to
-write to the console, to start applications or execute other ToolDef scripts,
-to manipulate paths, to interact with files and directories, and to
-manipulate data of the various supported data types.</p>
-</li>
-<li>
-<p>Easy to extend with new tools, written in ToolDef itself, or in
-<a href="http://oracle.com/java">Java</a>.</p>
-</li>
-<li>
-<p>Tools can be parameterized with types.</p>
-</li>
-<li>
-<p>Tools can be overloaded.</p>
-</li>
-<li>
-<p>Tools can have optional parameters.</p>
-</li>
-<li>
-<p>Tools can have a variable number of arguments.</p>
-</li>
-<li>
-<p>Tool invocations can use both positional and named arguments.</p>
-</li>
-<li>
-<p>Tools can return a single value, multiple values, or no values at all.</p>
-</li>
-<li>
-<p>Automatic type widening.</p>
-</li>
-<li>
-<p>Type declarations allow for reuse.</p>
-</li>
-<li>
-<p>Value semantics for ease of use.</p>
-</li>
-<li>
-<p>The usual imperative statements, including assignments, tool invocation,
-<code>if</code> statement, <code>for</code> statement, <code>while</code> statement, <code>return</code>
-statement, <code>exit</code> statement, <code>break</code> statement, and <code>continue</code>
-statement.</p>
-</li>
-<li>
-<p>Powerful assignment statement, including partial variable assignment, and
-multi-assignments.</p>
-</li>
-<li>
-<p>Variable declarations as statements, allowing variables to be declared in
-the middle of scripts, or in scopes, such as in bodies of <code>for</code> statements.</p>
-</li>
-<li>
-<p>Powerful <code>for</code> statement, allowing tuple unpacking, and iteration over
-values of various data types.</p>
-</li>
-<li>
-<p>A powerful import mechanism, allowing reuse of scripts, tools, and code.</p>
-</li>
-<li>
-<p>A registered library mechanism, allowing easy importing of libraries of
-tools.</p>
-</li>
-<li>
-<p>Platform independent path handling, allowing a single script with relative
-paths to be executed on Window, Linux, and Mac OS X.</p>
-</li>
-</ul>

-include new line characters (<code>\n</code>, Unicode U+0A). To include a double quote
-(<code>"</code>) in a string literal, it must be escaped as <code>\"</code>. Since a
-backslash (<code>\</code>) serves as escape character, to include a backslash in a string
-literal it must be escaped as <code>\\</code>. To include a tab character in a string
-literal, use <code>\t</code>. To include a newline in a string literal, use <code>\n</code>.</p>

-<p>Below you can find general information on how to use the ToolDef tooling,
-both on the command line, and in the <a href="https://eclipse.org">Eclipse</a> IDE.</p>
-</div>
-<div class="paragraph">
-<p>To start using the ToolDef tooling, create a <code>.tooldef</code> file. See the
-<a href="#lang-ref-chapter-index">language reference</a> documentation for more
-information on the syntax.</p>

-<h3 id="tools-command-line">Command line</h3>
-<div class="paragraph">
-<p>To execute a ToolDef script on the command line, use the <code>tooldef</code>
-executable. To start executing a ToolDef script, enter
-something like this on the command line:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="shell">tooldef some_script.tooldef</code></pre>
-</div>
-</div>
-<div class="paragraph">
-<p>
-
-Additional options are available, to influence how the script is executed. For
-details, execute the ToolDef interpreter with the <code>--help</code> or <code>-h</code> command
-line option:</p>
-</div>
-<div class="listingblock">
-<div class="content">
-<pre class="CodeRay highlight"><code data-lang="shell">tooldef --help</code></pre>

-</div>
-<div class="sect2">
-<h3 id="tools-eclipse-ide">Eclipse IDE</h3>
-<div class="paragraph">
-<p>
-
-To execute a ToolDef script in the Eclipse IDE, right click the file or an
-open text editor for the script, and choose <b class="menuref">Execute ToolDef</b>.
-Alternatively, choose <b class="menuref">Execute ToolDef…​</b> to first shown an option
-dialog, where several options that influence how the script is executed, before
-actually executing the script.</p>
-</div>
-<div class="paragraph">
-<p>It is also possible to start executing a script by pressing <kbd>F10</kbd>, while
-a <code>.tooldef</code> file is selected or an open text for such a file has the focus.
-Finally, clicking the corresponding toolbar icon
-(<span class="image"><img src="./tools/tooldef_icon.png" alt="tooldef icon"></span>) has the same effect.</p>
-</div>
-<div class="paragraph">
-<p>Execution of ToolDef script can be manually terminated by means of the
-termination features of the <em>Applications</em> view.</p>
