Review of various available spice simulators

Abstract

In this review paper we have tried to understand various existing transistor models defined, used and understood by various industry simulators viz., Spectre, LTSpice, PSPICE and HSpice. Comparative studies of industry standard spice simulators have also been done viz PSPICE, Spectre and HSpice. Towards the end numerical analysis method has been described to give an overview of the numerical methods used by various simulators during circuit analysis. The paper is organized into three sections. In Section I we discuss about various models understood by Spectre. We have given detailed discussion on each of the effects which are simulator specific and required in Spectre to achieve better and more accurate simulation results.
