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.




An open source ecosystem for IoT development. Cross-platform IDE and unified debugger. Remote unit testing and firmware updates.


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.


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.

Simulink® is a block diagram environment for multidomain simulation and Model-Based Design. It supports simulation, automatic code generation, and continuous test and verification of embedded systems.



OneWare Studio is the next generation IDE for electronics development. It supports a broad range of development languages including VHDL, Verilog, C++, and more. It is designed to streamline electronics development with features like a high-speed simulation viewer and advanced...




Scicos is a graphical dynamical system modeler and simulator developed in the Metalau project at INRIA, Paris-Rocquencourt center. With Scicos, user can create block diagrams to model and simulate the dynamics of hybrid dynamical systems and compile models into executable code.
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.



Emulino is an emulator for the Arduino platform by Greg Hewgill, originally found on emulino: arduino cpu emulator.
Does not offer circuit simulation features
