# XOR in domino logic

I was reading about domino logic and I noticed that several resources mention that domino logic can't be used for inverting functions like (NAND, NOR) and also can't be used for XOR.

I understand why we can't implement inverting functions, but why not XOR?

Can't we use a PDN that's similar to the PDN of an AOI22 and utilize inputs in their inverted and non inverted forms (A A_bar, B B_bar) ?

If you have A_bar and B_bar, then OR between them will give you NAND and AND between them will give you NOR. In that case, you can implement XOR also.
