Livewire is a sophisticated software package for designing and simulating electronic circuits.

QUCS is described as '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' and is a circuit simulator in the education & reference category. There are more than 25 alternatives to QUCS for a variety of platforms, including Windows, Linux, Web-based, Mac and Flatpak apps. The best QUCS alternative is Circuit JS, which is both free and Open Source. Other great apps like QUCS are LTspice, Altium Designer, Pspice and Proteus PCB design.

Circuit Solver is an electronic circuit simulator. You drag your electrical components and place them on one at a time. You hook up some sources and you place some meters to read the values.



Virtual Breadboard for Arduino is a learning 'app' version of VBB designed to help you take the first steps in the exciting world of physical computing with the Arduino microcontroller and ‘Breadboard’ based electronic circuit models.
oregano - An electrical engineering tool for GNOME
oregano is an application for schematic capture and simulation of electronic circuits. The actual simulation is performed by Berkeley Spice, or GNUcap or the new generation ngspice which is required for simulation, but not neces.






Drawlogix is a complete professional tool for the design, development and simulation of electronic circuits. Is extremely easy to use and offers optimum integration functions to focus solely on the design aspects of the work.



It is a circuit simulator on a virtual breadboard. it supports virtual components like microcontrollers, TTL, graphical and alphanumerical LCDs and others in addition to virtual instruments and certainly the basic components (resistors, capacitors..).
