Do you have any software recommendations for prototyping digital circuits with dynamic input? Things like buttons and midi. The trial and error process of breadboarding is nice for a tinkerer but I’d like to do it all in software.



It depends what you're doing - for analogue circuits the free software LTSpice is pretty great. It's clunky and you need to follow some tutorials, but it's a brilliant way to sanity check an analogue design before you build it. You can set square wave voltages to see dynamic performance.

If you want to simulate logic then logisim is really useful - you can design your circuit in terms of logic gates and then change inputs to see how it behaves - or generate a truth table. Good for checking that your logic works as expected.
