CircuitSim is described as 'Browser-based circuit designer and simulator with 3,000+ SPICE components, schematic capture, real-time analysis, netlist editor, and group features' and is a circuit simulator in the education & reference category. There are eight alternatives to CircuitSim, not only websites but also apps for a variety of platforms, including Windows, Mac, Linux and iPhone apps. The best CircuitSim alternative is Circuit JS, which is both free and Open Source. Other great sites and apps similar to CircuitSim are LTspice, Pspice, CircuitJS1 Desktop Mod and Multisim.
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.
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.
Software for Simulating Voltage and Currents of a text file net-list of a electronics components such as Resistors, Capacitors, inductors, transisters, Diodes, Voltage and Current Sources, etc.
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.
Multisim is industry-standard SPICE simulation and circuit design software for analog, digital, and power electronics in education and research.
Ngspice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. Ngspice is part of gEDA project, a full GPL'd suite of Electronic Design Automation tools.
iCircuit is the easy to use electronic circuit simulator and designer - the perfect tool for students, hobbyists, and engineers.
TINA Design Suite is a powerful circuit simulation package for analyzing, designing, and real time testing of analog, digital, VHDL, MCU, SMPS, RF, communication, optoelectronic and mixed electronic circuits and their PCB layouts.
