Modeling CHP descriptions in Labeled Transitions Systems for an efficient formal validation of asynchronous circuit specifications
Résumé
This work addresses the analysis and validation of CHP specifications for asynchronous circuits, using property verification tools. CHP semantics, initially given in terms of Petri Nets, are reformulated as labeled transition systems. Circuit specifications are translated into an intermediate format (IF) based on communicating extended finite state machines. They are then validated using the IF environment, which provides model checking and bi-simulation tools. The direct translation must be optimized to delay state explosion. Performance studies are reported.
