I don't see anything wrong.

Are you stepping the simulator after you enter the value for 'x'? I'm guessing that you are, since your Time is showing as 1 and I think you have to do this to get the internal pins updated.

Are you POSITIVE that you are using the built-in chips? Look in the directory that your ALU.hdl is in and be certain that there is no Inc16.hdl in there.
