Hello,

migration compatibilty takes care of these problems. Select all intended migration devices in Quartus devices setup and compile the project. Quartus *.pin file will tell you the required connection of all pins. It's particularly necessesary to connect all optional supply and GND pins. In- and outputs that can't be used in the migration compatible design revision can be decared as virtual pins.

Hi, thanks for the answer. I'm not sure if I got it right, but my issue is not what Quartus *.pin file will tell me, but that my board is fixed, and I might need to connect NC pins onto existing pads that are either GND or VCCIO. I dont have much choice about changing that, so the pinfile shall make no influence here. The question is about the damage of tying NC pins onto GND and VCCIO.
