Abstract

We propose to combine timed automata and linear hybrid automata model checkers for formal testing and monitoring of embedded systems with a hybrid behavior, i.e., where the correctness of the system depends on discrete as well as continuous dynamics. System level testing is considered, where requirements capture abstract behavior and often include non-determinism due to parallelism, internal counters and subtle state of physical materials. The goal is achieved by integrating the tools Uppaal [2] and PHAVer [3], where the discrete and hard real-time aspects are driven and checked by Uppaal TRON and strict inclusion of dynamical trajectories is verified by PHAVer. We present the framework, the underlying theory, and our techniques for integrating the tools. We demonstrate the applicability on an industrial case study.
