I think that what is happening is that the script is not loading the chip file with this code but probably a blank xor.hdl file.
To confirm this run your script. In  the bottom left corner of the hardware simulator is a frame captioned HDL.
Scroll down through this.
If it says '//implementation missing' it means that the xor.hdl file in the same folder as the xor.tst file that you are running in the hardware simulator is not the file that you put your hdl code in.
You need to put your hdl code in this file and then try again.
