Hi, I've successfully built a working Kogge-Stone CLA that adds properly. But I want to learn it to subtract. Since the absence of a Cin input, I decided to replace the first bit's half adder with a full adder, leaving everything else intact.
This circuit, however, fails, as the 4-value-bit won't propagate correctly when both x0, y0, Cin and x1 are active. Any help here?
Thank you in advance,
CX
