Large Scale Circuit Simulation System with Dedicated Parallel Processor SMASH
Summary :
This paper describes the circuit simulation system with dedicated parallel processor SMASH. SMASH is the parallel machine with the specialized hardware for LU decomposition of a large scale sparse matrix required in the circuit simulation. It shows the high performance when it has several decades of processor elements. First, we discuss the large scale circuit simulation system with SMASH and suggest the effcient interface of SMASH with the host computer with the consideration of circuit partitioning. This interface scheme uses the special structural memory unit constructed by 3 memory pages. By using this interface scheme, the host computer and SMASH can work independently. Furthemore, we estimate the performance of the simulation system. As the result of that, we show that the time required for the circuit simulation can be reduced to the evaluation time for element models. Moreover, it is shown that if the model evaluation is performed S times faster, the simulation speed also becomes S times faster by using SMASH and the interface scheme.
