New ContributorGuidance on Enabling USB Mode in F-Tile PMA Direct PHY IP – Quartus Prime 26.1
Hello,
I am currently working on USB 3.x data-rate implementation using the F-Tile PMA Direct PHY IP in Quartus Prime for the Agilex 7 device.
In earlier versions of the F-Tile PMA Direct PHY IP, the FGT PMA Configuration Rules parameter provided a USB mode. Selecting this mode enabled several USB-specific interfaces and features, including ports such as:
- fgt_rx_signal_detect_lfps
- fgt_tx_pma_elecidle
- Simplified TX Data Interface
However, in the newer Quartus Prime versions, including Quartus Prime 26.1, the USB option appears to have been removed from the FGT PMA Configuration Rules parameter.
Could you please guide me on how to enable or configure the F-Tile PMA Direct PHY IP in USB mode in Quartus Prime 26.1? In particular, I would like to know whether there is a supported Tcl command, configuration setting, or other method to enable the previously available USB PMA configuration.
I would appreciate any guidance or documentation regarding the recommended procedure for enabling the USB-specific PMA configuration and associated ports in the latest IP version.
Quartus Prime Version: 26.1
Regards,
HMV

In Quartus Prime Pro 26.1, USB is no longer a supported selectable value for FGT PMA Configuration Rules in the F-Tile PMA Direct PHY IP. The current supported values are Basic, OTN, CPRI, GPON, SDI, SONET, HDMI, SATA/SAS, PCIe, and PCIe_Phase2; USB is not listed.
There is no documented Tcl command or QSF assignment that restores the former USB configuration. The USB-specific ports and simplified TX interface were generated by the old USB protocol rule; they cannot be reliably recreated by manually setting ordinary PMA parameters.
