It looks nice and easy to use but I can't seem to get something as basic as a two-NOR flip-flop to work:<p><a href="https://i.imgur.com/V6yXpMl.png" rel="nofollow">https://i.imgur.com/V6yXpMl.png</a><p>The gates themselves in isolation work fine, but connecting them together doesn't. I even tried "bootstrapping" the circuit by breaking the storage loop and setting the two gates' inputs so they're all consistent first before connecting them together, but then when I disconnect the bootstraps it immediately returns to the above arrangement.<p>IMHO having trouble with something like that means the simulation engine is not quite usable yet...<p>Edit: the above circuit works fine in Logisim. Also, as another minor tangent, I think the flip-flop is so much easier to understand when it's drawn to emphasise the storage loop, i.e. the two NORs essentially become inverters when one of their inputs is 0, and they act in positive feedback to hold the bit value; why almost every other diagram insists on crossing the wires is perplexing, since it only serves to confuse and complicate.
