    If it's an input, tie it off in your code. If it's an output, does the VHDL OPEN work? The connectivity is an extra report to help find stuff, but there aren't assignment settings to control it.

    Also, if you see a warning for one you know is all right, you can suppress that message so it doesn't show up. It won't fix the connectivity report in the Compilation Report, but it will hide the message.
