Automatically places I/O pins of different V
pin assignments in separate I/O banks and enables the V
these I/O banks.
Verifies that voltage-referenced I/O pins requiring different V
levels are not placed in the same bank.
Reports an error message if the current limit is exceeded for a Stratix
or Stratix GX power bank, as determined by the equation
documented in
Reserves the unused high-speed differential I/O channels and
