Why do I get timing closure failures when compiling the Agilex™ 7 M Series EMIF Example Design for DDR5?

Environment

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

In Quartus® Prime Pro Edition Software version 24.1, when compiling the Agilex™ 7 M Series EMIF Example Design for DDR5, you will encounter the following Design Assistant Violations:

 

CDC-50012 - Multiple Clock Domains Driving a Synchronizer Chain

TMC-20027 - Collection Filter Matching Multiple Types 

 

These violations result in timing closure failures seen in the Timing Analyzer.

 

Resolution

The timing closure failures which result from these Design Assistant Violations can be ignored and will be updated in a later release of Quartus®.
