Adders

3 builds compete: 16-bit vertical adders of every design.

Fastest

#	Build	Latency	Volume
1	16-bit Carry Cancel Adder 2 copies of a 8-bit build, stacked unnecessarymb	4 ticks	2560 blocks per copy
2	16-bit torchless Carry Cancel Adder Aminotreal	7 ticks	1960 blocks
3	16-bit Ripple Carry Adder 16 copies of a 1-bit build, stacked unnecessarymb	34 ticks	768 blocks per copy

Smallest

#	Build	Volume	Latency
1	16-bit Ripple Carry Adder 16 copies of a 1-bit build, stacked unnecessarymb	768 blocks per copy	34 ticks
2	16-bit torchless Carry Cancel Adder Aminotreal	1960 blocks	7 ticks
3	16-bit Carry Cancel Adder 2 copies of a 8-bit build, stacked unnecessarymb	2560 blocks per copy	4 ticks

Most compact at each latency

Each is smaller than every build at least as fast, so going slower buys space.
