ID:15942 offsetctrlin[<number>] input of the DQS delay chain "<name>" can be driven only by the offsetctrlout[<number>] output of a DLL offset control

CAUSE: The specified offsetctrlin input of the specified DQS delay chain can be driven only by the corresponding offsetctrlout outputs of a DLL offset control. If the DQS_OFFSETCTRL_ENABLE parameter is set to FALSE, then the offsetctrlin input can also be disconnected.

ACTION: Change the design so that the offsetctrlin input is driven by the corresponding offsetctrlout outputs of a DLL offset control primitive, or if you want to disconnect the offsetctrlin input, set the DQS_OFFSETCTRL_ENABLE to FALSE.
