Symbolic SPICE

Symbolic SPICE is an analog circuit analyzer and approximator. It can be used as a pre-processor to find design formulas either directly or by making some global approximations. Symbolic SPICE can also be used as a post-processor using biasing point information of transistor parameters to approximate design formulas. Symbolic SPICE has a high degree of flexibility so as to be applicable to many different types of analog circuit problems. ----More details at---- http://www.willowelectronics.com/
