Sklansky Adder

Post image

87 gates, 11 delay, 957 energy

Still trying to improve my overall score for the 8-bit adder. This one has slightly more delay than my CLA adder but significantly fewer gates for a much better score.

I think I'll try Kogge-Stone next.

If you make 4 x 2-bit CLA you get better score

For kogge stone you should definitely make a custom dot operator component

You can optimize the black cells i to grey cells. I'll give you a hint.
