TEMPDIODE reading low

I'm reading the temp diode on a stratix IV fpga, and it reading about 50C below what it should be. It is changing in regards to thermal heat and cooling, but it always seems about 50C too low....

Just an update on this in case anyone else has the same problem... we had a 2200pF cap placed between the terminals that didn't have enough time to charge up during the reading. We probably could've went with a smaller cap, but unpopulating it seemed to work very nicely.
