ID:15986 OUTPUT_PHASE_ALIGNMENT primitive "<name>" with its phaseinvertctrl input fed by the dqoutputphaseinvert output of a DQS_CONFIG primitive must have its phasectrlin[<number>] input unconnected or fed by the dqoutputphasesetting[<number>] output of the same DQS_CONFIG primitive

CAUSE: The phasectrlin input of the specified output phase alignment primitive is driven by an illegal source.

ACTION: Check the design and make sure that the specified phasectrlin input is driven by either the dqoutputphasesetting output of a DQS configuration or unconnected.
