New ContributorAgilex 7 slew rate reconfiguration
We need to change dynamically (reconfigure) the transceiver TX slew rate. How can that be done?

Regular ContributorHi,
From your inquiry, I understand that you are looking into reconfiguring the TX slew rate for the Agilex 7 XCVR. Please correct me if my assumption is incorrect, but I am presuming you are referring to the F‑tile transceiver.
For your information, after reviewing the F‑Tile Architecture and PMA and FEC Direct PHY IP User Guide, I was not able to locate any specific info or 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?
Please let me know if you have any concerns or if you can share more context about your requirement. 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.
dncmrc1Hi,
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?
