Thank you, that makes more sense now and K-Maps are an easier again option.

If I build it from 2x Halfadders and 1 Or that is total of 15 Nand
If I use K-maps / simplified canonical form I get an different 15 Nand total layout.

Some googling shows me a Full adder implementation in 9 Nand! What is the next tool to derive this? Super K-maps? ;-)
