Occasional ContributorAgilex 7 slew rate reconfiguration
Hi,
For configuring TX Equalization on the Agilex™ 7 FGT PMA, you can use register 0x47830, which controls the TX EQ parameters. You may also refer to the proc set_txeq_settings procedure in the file ttk_helper_ftile_9_25.tcl, as it provides an example of how these settings are applied.
Feel free to let me know if you have any further questions. Thank you.
Regular ContributorHi,
Thanks for your clarification that you are referring to F-tile. As per my previous note, there is no configurable parameters related to TX slew‑rate control. Could you confirm whether you are instead referring to other PMA analog settings, such as TX pre‑emphasis? Thank you.
Occasional ContributorHi,
I meant namely the slew rate. But we will need to change also some other of the PMA settings (like pre-emphasis, yes). Can you please provide a list of the registers where these parameters can be reconfigured?

Hi,
Sorry for the delay. Regarding the ttk_helper_ftile_9_25.tcl, you can download it from https://cdrdv2.intel.com/v1/dl/getContent/850450 . You may refer to F-Tile Architecture and PMA and FEC Direct PHY IP User Guide -> "A.5. Transceiver Toolkit Helper Script" for further details.
Thank you.
