ID:181027 Cannot route DQS bus in <dqs_bus_mode> mode from <dqs_group> to <pin>

CAUSE: The Fitter cannot route the DQS bus associated with a DQS I/O group to the DQS, nDQS, or one of the DQ I/O pins in the group. This message may appear because pins in a DQS I/O group are constrained to I/O locations that cannot be driven by a DQS bus in the appropriate bus mode.

ACTION: Check location constraints applied to pins in the DQS I/O group and ensure that they correspond to valid locations for a DQS I/O group in the specified mode. If modifying these constraints does not resolve this issue, check for conflicts with other pins in your design.
