Quite Universal Circuit Simulator
From Wikipedia, the free encyclopedia
Quite Universal Circuit Simulator (Qucs) is a free-software electronics circuit simulator software application released under GPL. It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit. Pure digital simulations are also supported using VHDL and/or Verilog. Only a small set of digital devices like flip flops and logic gates can be used with analog circuits.[2] Qucs uses its own SPICE-incompatible backend simulator Qucsator, however the Qucs-S fork supports some SPICE backends.

Qucs supports a growing list of analog and digital components as well as SPICE sub-circuits. It is intended to be much simpler to use and handle than other circuit simulators like gEDA or PSPICE.
