Abstract

Fast distributed cosimulation is a challenging problem for embedded system design. The main theme of this paper is to increase the simulation speed by reducing the frequency of intersimulator communications, reducing the active duration of simulators, and utilizing the parallelism of component simulators. Those enhancements are accomplished by a proposed virtual synchronization technique, which combines event-driven and data-driven simulation methods. Experimental results show that the proposed technique can boost the cosimulation speed significantly compared with previous conservative approaches.
