ID:181007 Incompatible I/O standards detected for pins in the DQS group fed by DQS I/O pin "<name>" -- standards must have the same VCCIO and compatible VREF voltage requirements

CAUSE: The Fitter cannot place all of the DQ I/O pins driven by the DQS I/O because these pins have incompatible I/O standards. All pins in this DQS group are required to use I/O standards that have the same VREF and VCCIO voltages.

ACTION: If possible, modify the design to ensure that the I/O pins in the DQS group use I/O standards that have the same VREF and VCCIO voltages.
