Why do I see unconstrained Input/Output Ports at EMIF pins when I compile Intel Agilex® 7 FPGA M-Series EMIF IP?

Environment

  • Intel® Quartus® Prime Pro Edition
  • External Memory Interfaces (EMIF) IP
  • BUILT IN - ARTICLE INTRO SECOND COMPONENT
    Description

    You may see the unconstrained Input/Output Ports at EMIF pins when you compile Intel Agilex® 7 FPGA M-Series EMIF IP.

     

    Resolution

    You can safely ignore these unconstrained warnings.  The delay values for these pins are calibrated at run-time by the EMIF firmware, and those pins do not have values in Timing Analysis.

    This problem is scheduled to be fixed in future releases of Intel® Quartus® Prime Pro Edition Software.
