MEMORY_INTERFACE_DATA_PIN_GROUP
Specifies the group width (4, 9, 18, or 36), and associates a pin with another pin. Turning on this option
allows the Fitter to view the pins as part of the same memory interface pin group. I/O pins of this pin
group must be placed in the DQ pin locations of a single DQS group. This option is ignored if is assigned
to anything other than an I/O pad, input buffer, or output buffer.
