What does the error message at the bottom of the screen say? Those usually give you a pretty good job of at least pointing you in the right direction.

Looking at your code, I can see at least three errors.

Remember that busses and the ports they are connected to have to have the same width. The CPU has a mix of 16-bit and 15-bit busses, so you need to think about this carefully.

Also, if you have a signal named 'fred' connected to the input of a part, that signal must have a source driving it, either one of the chip inputs, or one of the outputs from another part within the chip.
