ID:176660 I/Os have a memory interface specific sub-block, but have no memory interface grouping assignment specified

CAUSE: The I/Os specified in the sub-messages have memory interface specific sub-blocks, but are not associated with a DQ_GROUP or MEMORY_INTERFACE_DATA_PIN_GROUP. To ensure that these sub-blocks get placed, the corresponding I/Os must be associated with a DQ_GROUP or MEMORY_INTERFACE_DATA_PIN_GROUP.

ACTION: Add memory interface grouping assignments to the specified IOs. In most cases, this can be done by running Tcl Scripts generated by the ALTMEMPHY MegaWizard.
