TAPAs is a software environment for supporting specification and analysis of concurrent systems via Process Algebras. TAPAs supports the use of process algebrae to specify and analyze concurrent systems. Systems are described as process algebras terms that are then mapped to Labelled Transition Systems (LTSs). Properties can be verified by checking equivalences between concrete and abstract system descriptions, or by model checking temporal formulae over the obtained LTS. Now TAPAs has its own wiki page and it is listed on Model Checking Tools wiki page. It is also inserted in this interesting verification tools database.
TAPAs is designed with a plug-in architecture: a set of software components (plug-ins) adds specific capabilities to a larger software application. Each plug-in supports a specific Process Algebra and it can be easy deployed in the TAPAs main application. Actually TAPAs has three different plug-ins that support three Process Algebras: CCSP, PEPA and StoKlaim.
