PCI_IO
Turns on Peripheral Component Interconnect (PCI) compatibility for a pin. For example, when the
VCCIO of an EP20K400 device operates at 3.3 V and PCI I/O is turned on for a pin, the Compiler clamps
the pin's signal to the VCCIO value, thus making the pin 3.3-V PCI-compliant. This option is ignored if it
is applied to anything other than a pin or a top-level design entity.
