ID:176693 HALF_RATE_INPUT atoms and DDIO_OUT atoms, which belong to the same DQS/DQ group, must all be driven by IO_CLOCK_DIVIDERs or all driven by the core

CAUSE: HALF_RATE_INPUT atoms and DDIO_OUT atoms in the DQS_ENABLE path which belong to the same DQS/DQ group, must all be driven by IO_CLOCK_DIVIDERs or all driven by the core.

ACTION: Try changing the clock source so that all the listed atoms, which belong to the same DQS/DQ group, are all driven by IO_CLOCK_DIVIDERs or all driven by the core.
