Another closeup of the adder. For this photo, I removed the top two metal layers and left the bottom metal layer. At the top, the partial sum circuit is repeated 8 times. At the bottom, XOR is repeated 8 times. In the middle, the carry lookahead circuitry is a jumble since each bit is different. 4/n
