For these two weeks, we will be using Logisim to virtualise circuits. I was unable to debug my 4-bit parallel full adder until my senior pointed out that there was a "hidden" wire between the input wires along one of the IC chips. He realised it because there was a circular dot at the point between the wires and the IC chip input locations.

4-bit parallel full adder (implementation by me) which works.
