Qt Universal Circuit Simulator

If you are looking for a powerful and user-friendly circuit simulator, then Qucs is definitely worth considering. This software is designed with a graphical user interface and aims to support all kinds of circuit simulation types, such as DC, AC, S parameter, and harmonic balance analysis, among others.

One of the standout features of Qucs is that it comes with Qucsator, which is a command line circuit simulator. This tool takes a network list in a certain format as input and outputs a Qucs dataset, making it incredibly useful for various types of circuit simulation tasks.

While Qucs has been designed specifically for usage in the Qucs project, it can also be used by other applications as well. Anyone who has experience using simulators like ADS© from Agilent Technologies or Microwave Office from AWR should find Qucs to be a powerful and intuitive option.

Overall, if you need a reliable and versatile circuit simulator that offers a range of powerful features, then Qucs is definitely worth checking out. Just be sure to meet the system requirements, which include Trolltech's Qt/Mac 3.3 and X11.
