Embedded systems assume increasing responsibilities in safety-critical automotive applications. For this class of applications, we have adopted a co-design approach based on successive validation phases. The first and most important design phase operates directly on an executable system specification, with a particular focus on fault modeling and robustness criteria, such as liveness and determinism. The second phase synthesizes subsystems into independent software processes that interact asynchronously with each other; the third phase results in a hardware/software prototype, for example a combination of FPGA and Microcontroller. We have applied this approach to the design of a bus-based airbag system.
