What is "sapwin"

Symbolic Analysis Program for Windows (SAPWIN) is a proprietary symbolic circuit simulator written in C++ for the Microsoft Windows operating systems Vista, 7.0 and 8.1. Unlike more common numerical circuit simulators (such as Simulation Program with Integrated Circuit Emphasis ( SPICE)), SAPWIN can generate analytical Laplace domain expressions for arbitrary network functions of linear analog circuits. The SAPWIN package also includes tools for schematic capture and graphic post-processing.

SAPWIN is available free from its homepage at the University of Florence website.
