CAUSE: The Fitter cannot place all of the DQ I/O pins driven by the DQS I/O because not all the pins are using the same on-chip termination (OCT) control blocks.
ACTION: If possible, modify your design to ensure that the I/O pins in the DQS group use the same INPUT_TERMINATION and/or OUTPUT_TERMINATION assignments. If your design manually instantiates OCT WYSIWYG primitives, you must ensure that all I/O pins in the DQS group are connected physically to the same OCT WYSIWYG primitive.
