SapWin
Symbolic Analysis Program for Windows 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, 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.SapecNG
Symbolic Analysis Program for Electric Circuits - Next Generation is the open-source software relative of SAPWIN, written in Boost C++ libraries and designed to be cross-platform. QSapecNG is a Qt-based graphical user interface and schematic capture program for SAPEC-NG.
