Why do I see marginal hold time failures when compiling the JESD204B IP targeting Intel® Stratix® 10 L-tile production devices?

Description

Due to different placement and fitting of the JESD204B IP compiled across different seeds in the Intel® Quartus® Prime Pro Edition Software, you might see marginal hold time failures for interfaces with data rates rates at 13.5 Gbps and 15 Gbps or above. You might see this problem when targetting Intel® Stratix® 10 L-tile production devices with a core speed grade of -2 or -1.

Resolution

Use Design Space Explorer to compare compilation results with different seeds and select the seed that passes timing.
