Will the 5CEFA4U19 chip work without some power pins connected as suggested by the Quartus migration feature.

Can anyone confirm by certain knowledge that pins marked "NC" in the pin connection guidelines for Cyclone V are truly not connected to the die? If NC does mean "not connected to the die," then it will be perfectly safe to apply power to those pins when the particular device being migrated to calls for a power connection. This is a simpler question to answer, and someone at Intel (or elsewhere) will really know that answer. Still doesn't account for the discrepancy between Quartus migration tool and the more and more likely eventuality that power may be tied to otherwise NC pins within the migration family. This would seem to be an error in the Quartus migration feature. Hopefully we can finally put this to bed for all those who have been confused by this important detail of vertical migration.
