Qucs

Qucs stands for Quite Universal Circuit Simulator.

Qucs is an integrated circuit simulator which means you are able to setup a circuit with a graphical user interface (GUI) and simulate the large-signal, small-signal and noise behaviour of the circuit. After the simulation has finished you can view the simulation results on a presentation page or window.

The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter and harmonic balance analysis.
