3-BIT ADDER

描述
Well just another 3bit + 3bit -> 4bit task.
Wireing might be the hardest part.
Can be solved with some PGA magic.

I did it, solved in 23/1290/0, PGA * 4 and NOT * 3

I used a PGA to rotate the inputs of A2, B0 and B1 to solve the wiring problem.

Nice, my best is 13/1277/24 with 2 MC6000 and 3 DX300.

Yea you are right, the lack of space is a pain in the ass and prevents experimenting, no idea why I did this :D

PGA is possible but expensive (I needed 4 + one negate gate):

Solved in 14/1420/28. Using 3 MCs and 3 expanders.

Tried to use PGA to solve this puzzle but failed. Maybe putting (a0, b0), (a1, b1) and (a2, b2) together will make this puzzle easier...
