a free and powerful circuit simulator

About

This application is mainly a circuit simulator that has evolved out of the project Qucs, but isn’t compatible with it. Many things have been completely reworked. It’s meant as a development environment for electrical engineers (graphical user interface, circuit simulator, PCB layouting, numerical data processing etc.), which can compete even with professional products. The application uses Qt4® by the Qt Company as graphical user interface.

Support

In order to keep the development alive, this project needs the support of its users, e.g. with:

  • bug reports, test results, documentation etc.
  • help other users in the forum
  • make a donation
  • companies, institutes etc., can become a sponsor (pay for technical support, tutorial videos, new features, …)

Programmers can help, for example, with the following tasks:

  • Create component libraries of the well-known companies
  • Programming extensions like filter synthesis, importing files (Gerber, STEP files, KiCAD, pcbmodelgen …)
  • EM simulation core for the method of moments, e.g. basing on GLMoM, Puma-EM or Scuff-EM
  • Improving the microstrip, stripline and coplanar models
  • Extending the functionality of the VerilogA interface or use OpenVAF
  • Creating new components in C/C++ or VerilogA including test circuits.
