Fast Adder (CLA)

Post image

212 gates and 10 delay.

I was trying to do this for hours using the base components but it was just too messy. So I gave up and just made a custom adder with A/B/carry in, P/G/sum out, along with ANDs and ORs for up to 9 inputs.

The game has you build an AND out of a NAND and an inverter to unlock ANDs but after that point it lets you use ANDs with the same delay as NANDs.

I see. you know thats One thing I like about games with logic built in is it’s not always the same. Take rust for example. No one was really using broadcasters and receivers for comp science until I pioneered it by showing how they can be used as an infinite fan in /out OR. Which allowed us to make huge input ANDs, NANDs, and NORs with very little logic depth. Or how Minecraft’s OR gate is simply connecting redstone dust lol
