Verification of dynamically reconfigurable embedded systems by model transformation rules

This paper describes a methodology for the verification of reconfigurable embedded systems. The reconfigurable systems are described by means of the Reconfigurable Discrete Event Specified System (RecDEVS) computational model and the verification is performed by a model transformation from the RecDEVS model into an equivalent representation for the UPPAAL model checking methodology. We introduce an algorithm for the automatic transformation of such models, which originate from disjoint application domains. This allows the usage of an state-of-the art verification tool for the verification of arbitrary properties of system specifications denoted in RecDEVS. We also present a set of important system properties, which now may be verified. This set includes some fundamental reconfiguration domain specific properties, which were not addressed by previous formal verification methods. The feasibility of this approach is demonstrated for a complex automotive application.
