Abstract

Modeling of Distributed Real-Time Embedded (DRE) systems allows one toevaluate models behavior or schedulability. However, assessing that a DREsystem’s behavior is correct in the causal domain is a challenge: one need toelaborate a mathematical abstraction suitable for checking properties likeabsence of deadlock or safety conditions (i.e. an invariant remains all overthe execution).In this paper, we propose a global approach to building Petri Nets models froman architecture described using AADL. We consider the semantics of interactingentities de- ?ned by AADL, and show how to build corresponding Petri Netsmodels. Based on a case study, we show how the veri- ?cation process could beautomated and parameterized.
