There is a bug in the HardwareSimulator that causes it to hang while loading if a Chip tries to use itself in the PARTS: section. This most often happens when students start working on Not.hdl.

CHIP Not {
    ...
    PARTS:
    Not(...);
}

When writing the Not chip, the only part that you can use is Nand.

Once you have successfully tested your Not, then you can use Not in new chips that you write. You should follow the order presented in the book: Not, And, Or, Xor, ... because you need to use the earlier parts to write the later parts.
