Description
You may see timing violations between the ports on the MPFE block using different clock frequencies because the Quartus®II software does not automatically cut these timing paths.
Resolution
There are no paths between the MPFE ports in the UniPHY-based hard memory controller. The failing paths can be safely cut using either the set_clock_groups or set_false_path SDC commands. Refer to the Quartus® II TimeQuest Timing Analyzer (.PDF) document for more information on the SDC commands.
