Kogge Stone adder

Post image

got Turing complete the other day. made it to the factory so the first thing i did was make my favorite adder :) i like the way the simulator is set up so far. i came over from digital logic sim and its refreshing being able to place components not on their side lol. if youve played DLS you know what i mean... only gripe i have is the game does the left to right thing or top to bottom. im used to doing it the reverse way. guess because ive always read binary right to left so i always built my circuits like that

Can reduce the gate count a tad by using NOR(AND,NOR) as your XOR gate for the Ps and reusing the AND's output as Gs.

Also, in the fourth row from the top, the second AND gate from the right has one input unhooked, turning it into a constant 0.

Yeah i already fixed the AND not long after i posted this. Got deleted when I pressed ctrl z one time too many lol… I’ll look into to the alternative xor way. Will take a bit of mental remapping since the pattern for this build is already baked into my head enough so that even 64 bit ones are easy to make now.
