A new piece of information .. if I obliterate the /db and /incremental_db and recompile .. then it works fine.

So in summary, I had a design from Quartus 8.1 that I recompiled in Quartus 13.0.1 from an archive. The first time I compile it, everything is fine. If I just hit play to compile again, without changing anything, I get that some of my pins have that SERIESTERMINATIONCONTROL error that is stated in the above post.

Then, if I obliterate the newly formed folders /db and /incremental_db and recompile .. it works.

Any suggestions.

Thank you!
