1.11.27. DQ_GROUP
Specifies the grouping from a DQS pin to its associated DQ pins and the width (4, 9, 18, or 36) of the group. Setting this option allows the Fitter to view the pins as a DQS/DQ pin group. I/O pins of a DQ 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.
