Simulation of bipolar VLSI circuits using overlapped relaxation technique

A fast and robust overlapped waveform relaxation (OWR) algorithm is presented for transient simulation of bipolar VLSI circuits. From the simulation results, it can be concluded that by using the OWR algorithm, the speedup can be two orders of magnitude compared to direct SPICE-like methods for very large circuits. Four representative examples, including combinational and sequential digital circuits as well as an analog bipolar circuit, are included. It is shown that the OWR algorithm is twice as fast as the waveform relaxation algorithm.<
