ID:21004 The dataout output of output phase alignment primitive "<name>" must drive dynamicterminationcontrol input of an I/O output buffer (directly or indirectly through up to 2 delay chain primitives) when OPERATION_MODE parameter is set to "rtena" or "extended_rtena"

CAUSE: The dataout output of the specified output phase alignment primitive has an illegal connection.

ACTION: Check the design and make sure that the specified dataout output is driving the dynamicterminationcontrol input of an I/O output buffer. You can also connect the dataout output to the dynamicterminationcontrol input indirectly through up to two delay chain primitives. In this configuration, the dataout output of the specified output phase alignment primitive would drive the datain input of a delay chain primitive and the dataout output of the same delay chain primitive would drive the dynamicterminationcontrol input of an I/O output buffer. Alternatively, you can change the value of the OPERATION_MODE parameter.
