QSapecNG is a Qt-based system pertaining to representational analysis associated with linear analog circuits. This program allows users to draw, solve and analyze analog circuits as well as manage them. It provides full support for sub-circuits, which can be created, saved, reopened and added as part of other circuits. It consists of two independent parts:
1) The SapecNG framework
2) The GUI of the application, QSapecNG.
It is an open source, multi-platform project, continuously enhanced by students and researchers of Department of Electronics and Telecommunications of the University of Florence.
