* Known issues | |
---------------------------------------------------------------------- | |
* Under Windows OS, export of a Fault Tree from the FT Viewer (both | |
image and pdf formats) produces a blank image/corrupted pdf | |
******************** xSAP 1.2.0 (2016/09/21) ******************** | |
This is a major release, containing new features. | |
---------------------------------------------------------------------- | |
* New features | |
---------------------------------------------------------------------- | |
o Diagnosability analysis | |
- Diagnosability analysis has been updated. Now it supports | |
specification of an LTL diagnosis condition, alarm specification | |
language (ASL) for exact delay, bounded delay and finite delay | |
patterns, and an LTL diagnosis context. A script has been added | |
to access this functionality. | |
o Generation of minimum observables set | |
- Generation of minimum observables set has been updated to match | |
the updates in diagnosability analysis. A script has been added | |
to access this functionality. | |
o Diagnoser Synthesis | |
- Added support for Context specificaiton and Fairness in the | |
synthesis algorithms. | |
- Top-level commands for synthesis have been simplified and a new | |
script (synthesise_fd.py) has been added. | |
o Antlr 3.4 | |
- xSAP now fully supports a more recent (3.4) version of antlr | |

* Bug fixes | |
---------------------------------------------------------------------- | |
* Various minor bugs have been fixed | |
---------------------------------------------------------------------- | |
* Known issues | |
---------------------------------------------------------------------- | |
* Under Windows OS, export of a Fault Tree from the FT Viewer (both | |
image and pdf formats) produces a blank image/corrupted pdf. Issue | |
will be investigated for the next release | |
---------------------------------------------------------------------- | |
* Superseded Commands | |
---------------------------------------------------------------------- | |
The following commands have been removed: | |
- synth_set_composition_semantics: replaced by the environment | |
variable synth_asynchronous_composition_semantics; | |
- synth_edit_observables has been replaced by the option -o | |
in synth_FD; | |
- synth_edit_alarms_spec has been replaced by the option -f | |
in synth_FD. | |
- compute_optimal_observables has been replaced by | |
diag_optimize_observables_asl | |

********************** xSAP 1.0.0 (2015/02/06) *********************** | |
This is the first major release of xSAP, the eXtended Safety Assessment | |
Platfor. It is a tool for safety assessment of synchronous finite-state | |
and infinite-state systems, based on symbolic model checking techniques. | |
xSAP supersedes FSAP (http://fsap.fbk.eu/), the Formal Safety Analysis | |
Platform. For details about license see xSAP s web page | |
(https://xsap.fbk.eu/). | |
---------------------------------------------------------------------- | |
* New features | |
---------------------------------------------------------------------- | |
xSAP provides the following main capabilities: | |
o Library-based specification of faults, fault effects, and fault | |
dynamics | |
o Automatic model-extension with fault specifications | |
o Fault Tree Analysis (FTA) and generation of Minimal Cut Sets (MCS) | |
for dynamic systems, for both the monotonic and non-monotic case | |
o Failure Modes and Effect Analysis (FMEA) | |
o Fault propagation analysis based on Timed Failure Propagation | |
Graphs (TFPG) | |
o Common Cause Analysis (CCA) | |
See xSAP web page (https://xsap.fbk.eu/) for the | |
complete list of features. | |
