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, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.
- schematic capture
- analog and digital simulations
- data visualization
Good work, good project for me.
absolutely great thing!
Hey I am sorry for previous bad review This is superb......
This is probably the most useful open source circuit simulator I ever found. It is accurate and (once you learn a bit) really easy to use.
This is a good program, but when I use the RLCG transmission line to generate a .s4p file, I meet a problem: In the frequency domain, there won’t be anything in the 1,3/1,4 or 2,3/2,4 combinations.
