Why do I see unconstrained Input/Output Ports at EMIF pins when I compile the 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 the 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 the Timing Analysis.

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