Quasi-one-step Gauss-Jacobi method for large-scale interconnect analysis via RLCG-MNA formulation

One or 2-step Gauss-Jacobi method is efficiently incorporated to the large scale interconnect analysis. In order to make the Gauss-Jacobi method within 1 or 2 iterations during each time step, the interconnect network is formulated by the RLCG-MNA formulation. In the numerical example, it is illustrated that the one-step Gauss-Jacobi method is 1,035 times faster than Berkeley SPICE and several tens times faster than INDUCTWISE which is known as the recent fast simulation method. Further, we show that the 2-step Gauss-Jacobi method is rational from efficiency and accuracy points of views
