2.1.1.22. Agilex 7™ DisplayPort IP Link-Up Issues in Quartus® Prime Pro Edition Software versions 25.1.1 and 25.3

Description

When using the DisplayPort IP on Agilex™ 7 F-Tile devices with Quartus® Prime Pro Edition software versions 25.1.1 and 25.3, you might encounter link-up failures due to non-optimized transceiver (XCVR) settings.

All data rates are affected when link training fails or reduces to a lower data rate.

For example, a request to link to HBR3 only achieves a link to HBR2. This issue is caused by suboptimal Rx Equalization register values in Quartus® Prime Pro Edition 25.1.1 and 25.3 releases.

Therefore, Altera recommends not to use Agilex™ 7 DisplayPort IP with Quartus® Prime Pro Edition software version 25.1.1 or 25.3 for production designs.

If you must use these impacted Quartus® Prime Pro Edition software versions, contact Altera support for further assistance.
