What's Qucs?

So far Qucs is not yet finished... but it is on the road.

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 that simulation has finished you can view the simulation results on a presentation page or window.

So far we were working on the GUI and on some basic simulation features. In fact there is now a kind of useful user interface for setting up schematics and presenting simulation results in various types of diagrams. DC, AC, S-parameter, noise and transient analysis is possible, mathematical equations and use of a subcircuit hierarchy are available. Anyway, a lot of work has to be done and thus we are looking for people who want to support the project.

A few first versions can be downloaded in the download section. Please keep in mind that these versions are still incomplete and we hope that some of you will be able to compile and run the package by their own. Some example schematics have been setup to demonstrate the abilities of Qucs.

Operating System

Qucs is currently developed under the GNU/Linux OS using the standard autotools with no special effort to support other operating systems. Qucs is said to be successfully compiled and run on Solaris, NetBSD, FreeBSD, MacOS, Windows and Cygwin... help is needed !

License

Qucs is released under the GPL license and so it is free for free programmers and users !
