Abstract: The work presented here is on setting up methodological support, including (prototype) tools, for the design of distributed hard real-time embedded control software for mechatronic products. The use of parallel hardware (CPUs, FPGAs) and parallel software is investigated, to exploit the inherent parallel nature of embedded systems and their control. Two core models of computation are used to describe the behavior of the total mechatronic system (plant, control, software and I/O): discrete event system (DES) and continuous time system (CTS). Thesemodels of computation are coupled via co-simulation, to be able to do consistency checking at the boundaries. This allows for integration of discipline-specific parts on the model level (during design phases) instead of on the code level (during realization and test phases). Crossview design-change influences get specific attention, to allow for relaxation of the tension between several dependability issues (like reliability and robustness), while keeping design time (and thus design costs) under control. Furthermore, the design work can be done as a stepwise refinement process. This yields a shorter design time, and a better quality product. The method is illustrated with a case using the tools being prototyped.
