    Circuit JS Alternatives

    Circuit JS is described as 'This is a javascript electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage' and is a popular circuit simulator in the education & reference category. There are more than 25 alternatives to Circuit JS for a variety of platforms, including Windows, Mac, Linux, Online / Web-based and Android. The best alternative is QUCS, which is both free and Open Source. Other great apps like Circuit JS are LTspice, OpenModelica, Xcos and SimulIDE.

    Circuit JS is mainly a Circuit Simulator but alternatives to it may also be Electronic Design Automation Tools. Filter by these if you want a narrower list of alternatives or looking for a specific functionality of Circuit JS.

    1. 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.
      Most users think QUCS is a great alternative to Circuit JS.
    2. LTspice IV is a high performance Spice III simulator, schematic capture and waveform viewer with enhancements and models for easing the simulation of switching regulators.

      Xcos is a graphical editor to design hybrid dynamical systems models. Models can be designed, loaded, saved, compiled and simulated.
    3. SimulIDE is a simple real time electronic circuit simulator. It's intended for general purpose electronics and microcontroller simulation, supporting PIC and AVR. PIC simulation is provided by gpsim and avr simulation by simavr.


    4. This electronic circuit simulator is highly interactive giving the feeling of playing with real components. It's very helpful for experimentation and visualization. It's a desktop version of the Circuit JS.
    5. The gEDA project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production.
    6. Sketch, simulate, and share your circuits, entirely in your browser -- no install required. Easy schematic capture and powerful SPICE-like, mixed-mode circuit simulation helps EE students, electronics hobbyists, and electrical engineers design faster.
