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.

01SapecNG

Symbolic Analysis Program for Electric Circuits - Next Generation (SapecNG) 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 (GUI) and schematic capture program for SAPEC-NG.

Symbolic circuit analysis

Symbolic circuit analysis is a formal technique of circuit analysis to calculate the behaviour or characteristic of an electric/electronic circuit with the independent variables, the dependent variables (voltages and currents), and (some or all of) the circuit elements represented by symbols. When analysing electric/electronic circuits, we may ask two types of questions: What is the value of certain circuit variable (voltage, current, resistance, gain, etc.) or what is the relationship between some circuit variables or between a circuit variable and circuit components and frequency (or time).
