Pin "K3" of FPGA "10M25DAF484"

Dear,

I am going to change "10M50DAF484" to "10M25DAF484".
According to product manual,
the pin "K3" of FPGA "10M25DAF484" is "NC" and the pin is "GND" for "10M50DAF484".

The report of Qurtus says "No Connect. This pin has no internal connection to the device."


Is it possible to stay "GND" ?


Thank you.

Hi Nakamura_kimi,
I would recommend to look to the similar thread: Will the 5CEFA4U19 chip work without some power pins connected as suggested by the Quartus migration feature.
I would recommend to look to Intel MAX 10 FPGA Device Family Pin Connection Guidelines (https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/pcg-01018.pdf).
There is the following fragment as an explanation of NC pin, section Reference Pins, p.12:
Pin Name = NC, Pin Type = No Connect, Pin Description = Do not drive signals into these pins. Connection Guidelines = When designing for device migration, these pins may be connected to power, GND, or a signal trace depending on the pin assignment of the devices selected for migration. However, if device migration is not a concern, leave these pins floating.

Regards,

Martin
