Zusammenfassung:Abstract: "We have just constructed a parallel logic-level simulation system based on Virtual Time. It was implemented on the Multi- PSI, the experimental parallel inference machine developed at ICOT. Our system simulates sequential circuits of practical size. Different delay times can be assigned to gates in the circuits. This paper proposes a new partitioning strategy of circuit data that is efficient for Virtual Time and also reports the measurement results of the simulator. In our experiment, a sequential circuit consisting of over 10,000 gates was simulated. Using 64 processors, the system indicated about 47k events/sec as its performance, and also indicated about 47 times speedup
This paper, using these results, denotes that Virtual Time is an efficient local synchronization mechanism and the new partitioning strategy proposed here can be a practical strategy.
