Abstract :
We have developed a highly parallel and accelerated circuit simulator which produces precise results for large scale simulation. We incorporated multithreading in both the model and matrix calculations to achieve not only a factor of 10 acceleration compared to the de facto standard circuit simulator used worldwide, but also equal or exceed the performance of timing-based event-driven simulators with the accuracy which matches that of SPICE-based circuit simulation. For example, a 89K element DRAM CAS circuit simulation can be performed in under 38 minutes with timing accuracy error as little as 7 ps
