iCircuit is described as 'The easy to use electronic circuit simulator and designer - the perfect tool for students, hobbyists, and engineers' and is a circuit simulator in the education & reference category. There are more than 25 alternatives to iCircuit for a variety of platforms, including Windows, Mac, Linux, Web-based and Flathub apps. The best iCircuit alternative is KiCad, which is both free and Open Source. Other great apps like iCircuit are Fritzing, Circuit JS, Square Sketch and QUCS.
KiCad is an open source software suite for electronic design automation (EDA) - designing schematics of electronic circuits and printed circuit boards (PCB). KiCad is developed by Jean-Pierre Charras. And features an integrated environment between schematic capture, bill of...
Open-source initiative aiding designers, artists, and researchers in transforming prototypes to actual products, documenting circuits, sharing, teaching, and PCB manufacturing.
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.
Digital graph paper for diagrams, technical sketches and geometric art.
This isn't for simulating circuits at all.
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.
LibrePCB is a free EDA software to develop printed circuit boards. It’s currently under heavy development to bring out first stable releases as soon as possible.
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.
Proteus PCB design combines the schematic capture and ARES PCB layout programs to provide a powerful, integrated and easy to use suite of tools for professional PCB Design.
