Parallel Logic Simulation of VLSI Systems

Abstract

Design verification via simulation is an important component in the development of digital systems. However, with continuing increases in the capabilities of VLSI systems, the simulation task has become a significant bottleneck in the design process. As a result, researchers are attempting to exploit parallel processing techniques to improve the performance of VLSI logic simulation. This tutorial describes the current state-of-the-art in parallel logic simulation, including parallel simulation techniques, factors that impact simulation performance, performance results to date, and the directions currently being pursued by the research community.
