QUCS Alternatives

    QUCS is described as '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' and is an app in the Education & Reference category. There are more than 25 alternatives to QUCS for a variety of platforms, including Windows, Linux, Mac, Online / Web-based and Android. The best alternative is Circuit Simulator, which is both free and Open Source. Other great apps like QUCS are LTspice (Free), Ktechlab (Free, Open Source), OrCAD (All Products) (Paid) and Circuit Simulator (CircuitJS1) (Free, Open Source).
