Combined data-driven and event-driven scheduling technique for fast distributed cosimulation

Fast distributed cosimulation is a challenging problem for the embedded system design. The main theme of this paper is to increase the simulation speed by reducing the frequency of inter-simulator communications, reducing the active duration of simulators, and utilizing the parallelism of component simulators. Those enhancements are accomplished by the 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 the previous conservative approaches.
