Protect name of an entity pin

I think I tried "Implement as output of logic cell". The problem is, that it is already a logic cell, and the manual states that it won't insert an additional lcell, if there is already one. At least I didn't see any change.

A more generic name definitely helps, yes. But there are many muxes in that cell, so I would have to put them all into the constraint (I can't distinguish them). I have no idea what this produces, maybe I should try ;) But I'm a bit afraid that this either produces an error (now that's an easy one to try) or ignores connections it shouldn't (this one rather less).

Maybe I should just figure out, why the name changes...
