Qucs briefly for Qt Universal Circuit Simulator, is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S parameter, harmonic balance analysis etc.
Qt Universal Circuit Simulator comes with Qucsator which is a command line circuit simulator. It takes a network list in a certain format as input and outputs a Qucs dataset. Qucs has been designed for usage in the Qucs project but may also be used by other applications.
For people who are familiar which such simulators they should remember ADS© from Agilent Technologies, Microwave Office from AWR and all the other simulators. This is an installer for Qucs 0.0.5
