ERROR:HDLParsers:856 - No default value for unconnected port

Yea, I should have seen this error coming. I was actually trying to look up where I could used 'open' because I didnt think I could use it for outputs and inputs. Looks like I was right.

This is caused from putting 'open' on an input port. You can only do that on output ports, for input ports you can make a dummy signal which will be synthesized out:
