Qucs 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, noise analysis, etc.
Until now there is no or little user documentation available. The Qucs application has an integrated help system giving the user useful but yet limited help with the program. We are searching for people who want to support the project by creating more documentation. The internal help system is also multi-lingual, thus translations into languages other than English, German, French and Spanish have to be done. If you are interested then feel free to write a email to: contact. It is planned to have user manuals consisting of
* the integrated multi-lingual help system
These should be little helpers with the program itself available during runtime including a getting started guide and brief descriptions of what is what in the graphical user interface (GUI). The documentation is written in simple HTML pages and focuses on the GUI.
* an english user manual with some more details
The actual user manual should contain a more detailed description of the simulation backend including the available program options, components and simulation types. The user manual focuses on the simulator and should be written in the Texinfo (texi) format, i.e. means it can be easily converted into info and HTML pages.
* tutorials about how to use Qucs
Topic-related tutorials dealing with certain issues, real life applications and how to handle these with Qucs. The tutorials will be available as pdf files and are written in LaTex. Available tutorials so far:
