An effective method to find all solutions of piecewise-linear circuits by analyzing piecewise-linear equations step by step

Recently, a lot of time has been required to analyze large VLSI transistor circuits and a faster algorithm was necessary. This paper describes a new system which obtains all solutions of a nonlinear circuit described by a piecewise linear function. It is expected that all solutions can be obtained in a practical time using the new method. In this paper, nonlinear circuits including Bipolar Junction Transistor (BJT) circuits are discussed, however, this method may be applied to any kind of nonlinear circuit described by a piecewise-linear function.
