List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit. Originally, Qucs was composed of a circuit simulator "qucs-core", now Qucsator, and a GUI for schematic entry and plotting. The usage patterns, as well as the emphasis on RF design, were ...
An arithmetic logic unit (ALU) capable of adding and subtracting 8-bit 2's complement integers from registers A and B. This module also has a flags register with two possible flags (Z and C). Z stands for "zero," and is activated if the ALU outputs zero. C stands for "carry," and is activated if the ALU produces a carry-out bit.
The CircuitLogix simulation engine is based on Berkeley SPICE, and contains a GUI to make circuit design easier and more efficient. The CircuitLogix 32-bit SPICE engine is interactive, allowing, for example, the frequency of sources to be changed, potentiometers adjusted, and switches thrown during simulation.
Mixed-mode simulation is handled on three levels: with primitive digital elements that use timing models and the built-in 12 or 16 state digital logic simulator, with subcircuit models that use the actual transistor topology of the integrated circuit, and finally, with inline Boolean logic expressions.
Multisim includes microcontroller simulation (formerly known as MultiMCU), [3] as well as integrated import and export features to the printed circuit board layout software in the suite, NI Ultiboard. [4] Multisim is widely used in academia and industry for circuits education, electronic schematic design and SPICE simulation. [5]
In August 1981, the analog equivalent of the first program, Circuit Designer and Simulator, was released. Its integrated text editor created circuit descriptions for a simple, linear, analog simulator. September 1982 saw the release of the first Micro-Cap package as a successor to the Circuit Designer and Simulator. 1982 Micro-Cap; 1984 Micro-Cap 2
Oregano is a graphical software application for schematic capture and simulation of electrical circuits. The actual simulation is performed by the SPICE, Ngspice or Gnucap engines. It is similar to gEDA and KTechlab. It makes use of GNOME technology and is meant to run on free Unix-like operating systems such as Linux, FreeBSD et al.
