| This use case presents the import of SILDEX models (a synchronous language based graphical modelling formalism developed by |
| <a href="http://www.tni-software.com/">TNI</a> and currently in use at <a href="http://www.airbus.com/en/">AIRBUS</a>) in AADL/COTRE. |
| It was implemented in ATL by <a href="http://www.c-s.fr/">C-S</a> in the context of the TOPCASED project. |
| </p> |
| <p align="justify"> |
| SILDEX is a CASE tool supporting SIGNAL synchronous languages. It provides graphical and SIGNAL code editing of each process and relevant dataflow; formal proof with |
| "synchronous compilation"; dynamic simulation; ADA, C and FORTRAN code generation, and documentation production. SILDEX was designed and tested in Smalltalk, then |
| translated into C code with TNI's OpenTalk compiler. SILDEX targets critical real-time software developments. |

| <a href="http://www.topcased.org/">TOPCASED</a> is an open-source workshop based on an Eclipse platform. Several editors are available: |
| SAM, AADL, UML2, ECORE, and SYSML. |
| It integrate several transformation services. These services are based on ATL language and toolkit. Model transformations have been mainly used in order to |
| access models defined using other editors than TOPCASED one's. Other services around models are available like OCL editor and checker, comparison, merging, etc. |
| </p> |
| <p align="justify"> |
| <a href="http://gforge.enseeiht.fr/projects/topcased-aadl/">TOPCASED-AADL</a> is a subproject of the TOPCASED project. This subproject provides a set of modeling, |
| transforming and verifying tools around AADL (Architecture Analysis and Design Language). These tools are based on the AADL metamodel that has been developped by the |
| SEI for the <a href="http://www.aadl.info/">OSATE</a> project. AADL/COTRE is a language (including AADL) resulting from the |
| <a href="http://www.laas.fr/COTRE/work/output/cotre-erts.pdf">COTRE project</a>. |
| </p> |
| <p align="justify"> |
| From the YACC grammar of AADL/COTRE, a metamodel has been defined. The following example shows an excerpt of the available grammar: |

| <p align="left"> |

| <br /><br /> |
| <b></b> |
| </p> |
| <p align="justify"> |
| This metamodeling process implies an iterative approach revealing new reductions with each iteration. |
| The following example shows the result of the metamodeling process: |

| <p align="justify"> |
| After the creation of the source metamodel SILDEX and the target metamodel AADL/COTRE, the TOPCASED process to make a transformation can be breakdown as follow: |
| <ul> |
| <li>first, the mapping of the concepts, </li> |
| <li>then the writing of the ATL transformation rules and the automatic transformation by rule execution (also with ATL),</li> |
| <li>at last, manual check of the result through the reading of the files obtained by the editors (in this use case TOPCASED AADL Editor).</li> |
