| Summary: | This paper shows a methodology for Globally-Asynchronous-Locally-Synchronous (GALS) systems specification and verification. The distributed system is specified by non-autonomous Petri net modules, obtained after the partition of a (global) Petri net model. These modules are represented using IOPT (Input-Output Place-Transition) Petri net models, communicating through dedicated communication channels forming the GALS system under analysis. This set of modules is then automatically translated into Maude code through a MDA approach. As the modules of GALS systems run concurrently, the Maude semantics for concurrent objects is used along with message representation. Finally, as a particular case, the system state space is generated from the Maude specification of the GALS system, allowing property verification.
