ID:186354 DQS I/O pin "<name>" referenced by system clock "<name>" is using a different system clock than other DQS I/O pins in its DDR pin group (which use system clock "<name>")

CAUSE: The specified DQS I/O pin is referenced by a different system clock than the other DQS I/O pins in its double data rate (DDR) pin group. All DQS I/O pins in a DDR pin group must be referenced by the same system clock.

ACTION: Modify the design so that the DQS I/O pin is referenced by the same system clock as the other DQS I/O pins in its DDR pin group.
