QSapecNG is a Qt-based program for symbolic analysis of linear analog circuits.
In fact, it consists of two indipendent parts: the SapecNG framework engine and the application gui QSapecNG. It comes as continuation of SapWin for Windows, in order to give to the project a full compatibility on other platforms.
Through SapecNG/QSapecNG users can draw, solve and analyze analog circuits as well as manage them. There is also the full support for sub-circuits, which can be created, saved, reopened and added as a part of the other circuits.
