ID:169023 Too many pins (<number>) in I/O bank <name> assigned near VREF pin <name> -- no more than <number> are allowed near the VREF pin

CAUSE: You assigned the specified number of pins to the specified I/O bank near the specified VREF pin. However, the number of pins exceeds the limit for that VREF bank and can cause instability in the VREF voltage, which can cause any inputs depending on that VREF pin to be read incorrectly.

ACTION: Reassign some of pins to a different VREF bank. To display I/O banks, open the Chip Planner and turn on I/O bank display IN the Layers Settings dialog box.
