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

Thank you for the confirmation. Oddly it is the smaller die that has the extra power connections. Now the remaining issue is the bug in Quartus vertical migration tool, which does not correctly show the power connections for proper migration. Now I have to manually compare the spread sheets for each one of the chips in the desired migration path. Each pin that is supposed to be power, but is NC in another chip in the family must be properly identified and connected. At least users should be warned not to assume the migration tool is giving correct or complete results.
