In this paper, we apply CGS algorithm for large scale asymmetric sparse matrix in semiconductor device simulation. We used CGS algorthm in Semiconductor Device Simulation Software SMDS and completed the core computation. For solving several encounted problems in this application, we present solutions of dual iteration technology and good selection of rejection factor which can guarantee the convergence and reduce the time of the iteration.
