Abstract : We present in this paper a method and tool for the verification of causal and temporal properties of embedded systems, by analyzing the trace streams resulting from virtual prototypes that combines simulated hardware and embedded software. The proposed method makes it possible to analyze different kinds of properties without rebuilding the simulation models. Logical clocks are used to identify relevant points to put observation probes and thus also reducing the trace streams size. We propose a property specification language, called PSML, and based on behavioral patterns that does not require knowledge of temporal logics. From a given PSML specification, simulation is instrumented to generate a trace and the code is dynamically loaded by the simulator. The resulting trace stream is analyzed by parallel automata generated from the specification. The experiments, developed over the SimSoC virtual prototyping framework, show flexibility, possibility of using multi-core platforms to parallelize simulation and verification, providing fast results.
