annoying warning during synthesis.

Ugh. Sorry, but not an easy one. In justification:

- It is difficult to write IP that has no warnings, but parameterized IP is significantly more difficult. (It's just too easy to let synthesis reduce a bus to the correct size of something like that).

- It is difficult to say a warning is all right under all conditions. We don't want to do a blanket suppression, as there may be cases where the user has hooked something up incorrectly, and the warnings in the IP are what would identify that. Although with too many warnings, it's probably too difficult to know what's real and what's not.

Anyway, it's difficult, but Altera should do a better job of it, no doubt about it. I know this is always on the radar, but not sure what/when will happen.
