Design & simulate gates & PLAs with transistors & diodes, Processors with integrated logic components, using std_logic signals. Easy to wire buses, reverse polarity of discrete parts, or change parts to open collector. Even apply DeMorgan on gates!.

SimuGate is described as 'Python simulation of logic gates, circuits, down to transistor level using std_logic levels. This served as a prototype for the faster and more fully featured jSimuGate, also on GitHub - innovation-plantation/simugate' and is a circuit simulator in the education & reference category. There are 2 alternatives to SimuGate for Linux, BSD, Java, Mac and Windows. The best SimuGate alternative is jSimuGate, which is both free and Open Source.
