Do you have the Not part already implemented and tested?

If so, the attach your And.hdl file and I will take a look to confirm that there is nothing subtle that is wrong with it.

no.And gate is my first.
i test it in wsl and windows11.the result is 1 Nand 1 = 1 when i test And.hdl
but in Ubuntu the result is right.

I have no idea was wsl is.

You can't expect an And gate implementation that requires a Not gate to work properly if you haven't implemented the Not gate.

You need to implement the parts in the order that they are presented by the Authors. If you don't, then the behavior of the simulator is pretty much undefined and depends on a number of factors, which may include which operating system you are using and the phase of the moon.
