I try to implement a full adder circuit using square arrays.
I've used Digital software to design it. Also I've tested it. It works fine.
But my implementation is quite different from the circuit shown by the lecturer.
As you'd see, to be able get correct results I switched the outputs (S and Cout)
Also as you'd recognise the layout of NFET gates are different.
Is the layout of NFET gates correct? Thanks.
Update: My temporarily solution is like this.
