Your chip won't "do" anything by itself. You need to run a test script that loads the chip and sets its input to various values. There should be a test script for that in the project folder. In any case, when I tried to load your ALU I got the error message that "a in not a pin in Not". This is probably just because the built-in chip uses "in" for the input line instead of "a" which you probably used in your Not chip. If your chip loads without error, try running the test script.
