Why are UI and MEM_DQ_FREQ_PS set to tCK in *_ip_parameters.dat?

Environment

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

Due to a problem in the Quartus® Prime Pro Edition Software version 24.1 and earlier, the value of UI and MEM_DQ_FREQ_PS are incorrectly set to tCK in the *_ip_parameters.dat file generated by External Memory Interfaces (EMIF) IP in designs targeting Agilex™ 7 FPGA F-Series and Agilex™ 7 FPGA I-Series devices.

.param UI                   = 0.625

.param tCK                  = 0.625

.param MEM_DQ_FREQ_PS       = 625.0

Resolution

Use UI = 1/2 tCK when evaluating WR eye and RD eye.

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