Im not sure if Im posting in the right sub, so I apologize in advance.

So Im trying to build a 4-bit 2's Compliment Multiplier on logisim.

Here what I have so far: https://imgur.com/a/S16CtkC ... The first pic is like an overview/drafting, the little chart on the right is accurate I think. The second pic is what I have made so far. The third pic is my 4-bit inverter. And my fourth pic is my 8-bit inverter.

So where Im stuck is the unsigned multiplier. Im not really sure how to build this :/

Any pointers/help would be appreciated!
