The Quite Universal Circuit Simulator (QUCS) is an integrated circuit simulator allowing the simulation and graphical presentation of results of large-signal, small-signal and noise behavior in circuits.




There are many alternatives to Circuit JS for Windows if you are looking for a replacement. The best Windows alternative is QUCS, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to Circuit JS and many of them are available for Windows so hopefully you can find a suitable replacement. Other interesting Windows alternatives to Circuit JS are LTspice, Multisim, SimulIDE and CircuitJS1 Desktop Mod.
