Agilex 7 slew rate reconfiguration

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

    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.

Hi,

I am referring to L_ and H-tiles, not F.

We are already reconfiguring pre-emphasis and VOD, no issue with them.

What I am asking here is about TX slew rate. We are already doing that with e.g. Arria 10 but now we need to do it also with Agilex 7. I am pretty sure there must be there as well a register for reconfiguring it.

Regards

    Hi,

     

    Thanks for the update. From your description, I understand you are referring to L/H tiles. Could you please confirm if you are talking about Stratix 10 devices, which support L/H tiles?

     

    Thank you.

      Hi,

       

      Sorry, my bad. I am referring to F-tiles and Agilex 7.

      I got confused since I have another issue related to Stratix 10 and L/H tile.

      But this issue is indeed referring to F-tiles and Agilex 7, sorry.

      Regards
