LTspice Alternatives

    LTspice is described as 'IV is a high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators' and is an app in the Education & Reference category. There are more than 25 alternatives to LTspice 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 LTspice are QUCS (Free, Open Source), Xcos (Free, Open Source), OpenModelica (Free, Open Source) and Ktechlab (Free, Open Source).
