Model Based Embedded System Development for In-Vehicle Network Systems

This paper aims for a seamless development process for automotive body network system development with model-based approach. It also describes a generic software architecture that provides clear-boundaries between the software components and that can also act as a guide for each development phase. The CASE tool Statemate is used for feature behavioral modeling and verification. NodeAllocator builds the ECU models by mapping the behavioral model and physical network architecture. The virtual prototypes and the basic bus communication information are created and validated using software in loop simulation. The validated functional models are refined for implementation models and MicroC is used for application task code, OS design and software integration.
