Also, 0.5 ticks does not make much of a difference, most instant carry adders still become 5+ ticks, with 4.5 being the worst case delay in a truly 3 tick instant carry adder. Which would, by the way, require a 1 tick XOR, so I'd still love to see it. I made one, but repeaters had to be used to extend the signal past 3 bits, so I'd like to see 8 bits calculated in 3 ticks since you say it can be done.
Ask Dcentricts to look at his adder it can do 4 tick addition of 8 bits.
