Abstract Animator for Temporal Specifications
Résumé
Temporal specifications provide an abstract and powerful framework for modelling (reactive) systems with respect to safety, liveness and fairness properties, for example, telecommunications services and the feature interaction problem. However, techniques and tools are required for analysing temporal specifications as for instance model checking-based techniques or theorem proving-based techniques, because temporal notations are powerful expression of rich concepts (fairness) and are then very difficult to validate. We focus our work on TLA/TLA+ as a specification language, but we require the possibility to validate temporal specifications by animation with respect to an abstraction.
