ID:15873 Output port <name> of DDIO_OUT primitive "<name>" must drive input port <name> of an I/O OBUF primitive. It currently drives "<name>"

CAUSE: The specified DDIO_OUT atom is not connected properly. It should drive the specified port of an I/O OBUF primitive, but it is not doing so. This can happen if you are compiling a design with a Memory Interface IP generated from a previous version of the Quartus Prime software.

ACTION: Check your design to make sure that the DDIO_OUT atom is properly connected. If the specified DDIO_OUT is generated by an IP from a previous version of the Quartus Prime software, make sure that you re-generate the IP files using the current version of the Quartus Prime software.
