I'm in college and currently taking computer organization. I'm in the first chapter (Boolean Logic) of my textbook.

I tried doing the implementation of a Xor gate using a hardware simulator, but it kept giving me "Comparison failure at line three" (as shown in the screenshot). Below is a screen shot of the hardware simulator, along with the other files needed to run the simulator.
