A compiled-code parallel pattern logic simulator with inertial delay model

Abstract

This gaper presents a parallel pattern compiled code logic simulator which can handle the transport delay as well as the inertial delay of the logic gate. It uses Potential-Change Frame, incorporating with inertial functions, to execute event-canceling operation for gates, thus eliminating the conventional time wheel mechanism. As a result, it can adopt the parallel pattern strategy to increase the simulation speed. Furthermore, it is a compiled code simulator, which further improves its performance. Experimental results show that it surpasses significantly over the conventional time wheel. event-driven simulator in the simulation speed. In addition, it is also found that, significant percentage (27%) of hazards should be eliminated when only the transport delay is considered in the simulation.
