Application of temporal decoupling to the creation of efficient performance models of automotive architectures

Due to the increasing complexity of communication infrastructures in the automotive domain, reliable models of embedded system architectures are necessary in order to assist designers in the development process. In this context, transaction level modeling, supported by languages as SystemC, is a promising solution to allow performances of networked architectures to be assessed with different compromise between accuracy and simulation speed. In this paper, a modeling technique is proposed to improve the simulation speed of architecture models used for performance evaluation. A specific case study inspired from the automotive domain is used to illustrate how simulation speed-up is achieved using the proposed technique. A significant simulation speed up by an order of magnitude of 100 is achieved in the considered case study.
