I think the initial comment about using a XOR mentioned a couple of gates for
A trick from the old FPGA days. You can guarantee that the pulse is wide
enough to clock a FF if you put a FF in the chain. That is replace the
gates-for-delay with a FF. Use the pulse to clock the FF and feed the output
of the FF to the other side of the XOR. (You may need some delay on the
input to the FF to meet setup time. You have the XOR delay to start with.)
These are my opinions. I hate spam.
