Why is the Restricted Fmax of *_vco_clk and *_vco_clk_1 of External Memory Interfaces Intel® Arria® 10 FPGA IP much lower than Fmax in the Fmax Summary report?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 22.2 and earlier, you might find that the Restricted Fmax of *_vco_clk and *_vco_clk_1 of the External Memory Interfaces Intel® Arria® 10 FPGA IP is much lower than the Fmax in the Fmax Summary report.

Resolution

You can safely ignore the Restricted Fmax for the target External Memory Interfaces Intel® Arria® 10 FPGA IP clocks.

This problem is fixed beginning with the Intel® Quartus® Prime Pro Edition Software version 22.3.
