Abstract
Modern Cyber-physical Systems are executed in physical environments and distributed over several Electronic Control Units using multiple cores for execution. These systems perform safety-critical tasks and, therefore, have to fulfill hard real-time requirements. To face these requirements systematically, system engineers develop these systems model-driven and prove the fulfillment of these requirements via model checking. It is important to ensure that the runtime scheduling does not violate the verified requirements by neglecting the model checking assumptions. Currently, there is a gap in the process for model-driven approaches to derive a feasible runtime scheduling that respects these assumptions. In this paper, we present an approach for a semi-automatic synthesis of behavioral models into a deterministic scheduling that respects real-time requirements at runtime. We evaluate our approach using an example of a distributed automotive system with hard real-time requirements specifi ed with the MechatronicUML method.
