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.




Micro-Cap is described as 'Integrated schematic editor and simulator. Dynamic analysis updates waveforms and curves as you edit Native digital simulator Worst Case analysis to find the statistical and extreme limits of performance Smoke Analysis to assess how close the circuit is to violating maximum opera' and is a circuit simulator in the education & reference category. There are more than 25 alternatives to Micro-Cap for a variety of platforms, including Windows, Linux, Mac, Web-based and Flathub apps. The best Micro-Cap alternative is KiCad, which is both free and Open Source. Other great apps like Micro-Cap are Circuit JS, QUCS, LibrePCB and Autodesk EAGLE.

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.








Qucs-S is a spin-off of the Qucs cross-platform circuit simulator. "S" letter indicates SPICE. The purpose of the Qucs-S subproject is to use free SPICE circuit simulation kernels with the Qucs GUI.


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.

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.




eSim (previously known as Oscad / FreeEDA) is an open source EDA tool for circuit design, simulation, analysis and PCB design.




iCircuit is the easy to use electronic circuit simulator and designer - the perfect tool for students, hobbyists, and engineers.


Logisim is an educational tool for designing and simulating digital logic circuits. It has been originally created by Dr. Carl Burch and actively developed until 2011. After this date the author focused on other projects, and recently the development has been officially stopped...



atopile is a language and toolchain to describe electronic circuit boards with code. By replacing the point and click schematic interface with code, we introduce software development workflows like reuse, validation and automation to the world of electronics.

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.
