Electrical circuit simulation was one of the first CAD tools developed for IC design. The
conventional circuit simulators like SPICE and ASTAP were designed initially for the cost effective analysis
of circuits containing a few hundred transistors or less. A number of approaches have been used to improve the
performances of congenital circuit simulators for the analysis of large circuits. Thereafter relaxation methods
was proposed to provide more accurate waveforms than standard circuit simulators with up to two orders of
magnitude speed improvement for large circuits. In this paper we have tried to highlights recently used
waveform and point relaxation techniques for simulation of VLSI circuits. We also propose a simple
parallelization technique and experimentally demonstrate that we can solve digital circuits with tens of million
transistors in a few hours.
Key words: Circuit simulators, gauss-seidal, itrative algorithm, point relaxation, relaxation, transient analys,
