This is my upgraded design for a 16-bit adder. It is the absolute smallest possible width of a 16-bit adder. The inputs require no bus to be organized, and the outputs come right to the display region. The final dimensions are 21x33x10 (Length x Width x Height). Because of the large amount of inverters and repeaters in the full adders, there is a noticeable delay. For a more speed-oriented adder, see my previous project.

Additional Notes

If you would like an output in the back, just reroute it from the accessible torch near the back.
