CircuitLogix

The graphic user interface allows students to quickly and easily draw, modify and combine analog and digital circuit diagrams.

In 2012, it reached the milestone of 250,000 licensed users, and became the first electronics simulation product to have a global installed base of a quarter-million customers in over 100 countries.

[1] CircuitLogix was developed by Dr. Colin Simpson, an electronics professor at George Brown College, in Toronto, Canada, and John (Bud) Skinner, a computer programmer.

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 by CircuitLogix: (a) with primitive digital elements that use timing models and a built-in 12-state digital logic simulator, (b) with subcircuit models that use the actual transistor topology of the integrated circuit, and finally, (c) with In-line Boolean logic expressions.
