Simulation for the distributed system with consideration of hardware characteristics

Developing and validating a distributed system requires great cost, time, and effort than a centralized system because the systems are inherently concurrent, asynchronous, and nondeterministic. For this reason, accurate simulation function is significantly important for developing the distributed system. In particular, it finds applications in the automobile embedded system industry, which requires short time-to-market. If the simulation function is able to simulate the hardware characteristics of the distributed system, the accuracy of the simulator increases. We develop a 16-bit embedded system for an electronic control unit (ECU) in an automobile system and a block for modeling and simulating for distributed system with considering of hardware characteristics, especially caused by network characteristics. In this paper, consequence of simulation with real-value in the 16-bit embedded system is compared.
