Why is the "Start PMA DFE adaptation auto" feature of the L-Tile/H-Tile Transceiver Native PHY Stratix® 10 IP not function?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 25.3.1 and earlier, the RX PMA DFE adaptation does not automatically start upon device power-up, a full user reset sequence, or a user triggered RX link reset when the “Start PMA DFE adaptation auto” option is selected in the “RX Analog PMA Settings” section of the IP GUI.

Resolution

There is currently no plan to fix this problem.

To work around this problem, you may enable RX PMA DFE adaptation by following Section A.4.2.6 “Adaptation Control - Start” of the L- and H-Tile Transceiver PHY User Guide.
