If we were to try to run much more than some really simple circuits, it
would need things like multi-bit buses and a much faster simulator and
subcircuits (though I think it may already have subcircuits).

Try and see how fast the QAM-256 example is, since that's a more
complicated circuit.

BTW, the offline Java version is quite a bit faster than the online version
which is made using a Java to Javascript translator (GWT).

Maybe write a BLIF to CircuitJS translator :)
allows us to export from yosys to circuitjs
