Distributed Parallel Simulation and Synchronization.


As the complexity of chip designs increase, simulation time also increases. Unit and variable delay simulation takes the most simulation time in IC design process; however, parallel processing performs inefficiently due to large amount of synchronization. In this paper, techniques to reduce the number of synchronization points in synchronous designs are proposed, and a partitioner to partition designs along flip-flop boundaries is also proposed so that these techniques can be employed on real designs.
