    This paper 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 inertial functions, to execute event-canceling operation of 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 significantly surpasses the conventional time wheel event-driven simulator in terms of simulation speed. In addition, it is also found that a significant percentage (27%) of hazards can be eliminated when the effect of the inertial delay is considered in the simulation.
