Missing MDIO Module in Triple-Speed Ethernet IP for Agilex-5 in Quartus 24.3.1

Hello,

In Quartus 24.3.1, when selecting an Agilex-5 FPGA (A5ED065BB32AE5SR0) for the Triple-Speed Ethernet Intel FPGA IP, we noticed an issue with the MDIO Module availability.

In the "Core Configurations" tab, when choosing "10/100/1000Mb Ethernet MAC with 1000BASE-X/SGMII 2xTBI PCS" as the Core variation, the "MDIO Module" section is missing from the "MAC Options" tab. However, for other core variations ("10/100/1000Mb Ethernet MAC", "10/100/1000Mb Ethernet MAC with 1000BASE-X/SGMII PCS", "1000Mb Small MAC", and "10/100Mb Small MAC"), the "MDIO Module" section appears as expected.

Could you please clarify how we can access the MDIO port (MDC/MDIO) of an Ethernet PHY when using the "10/100/1000Mb Ethernet MAC with 1000BASE-X/SGMII 2xTBI PCS" configuration?

For reference, we don't face this issue if we choose an Agilex-7 FPGA.

Thank you for your support!

    Hello,

    This issue is blocking our progress. Could you please provide a solution?

    We need to program the PHY using a TSE IP core that utilizes a GTS transceiver in the PCS layer. However, we have not found an MDIO module in the corresponding TSE configuration for Agilex-5 FPGAs.

    We look forward to your response.
    Thanks!

    Hello,


    Apologies for the delayed response.

    Yes, we are aware of the missing MDIO module in Agilex 5. We have worked on it and the fix version will be included in upcoming Quartus release.

      Hello Pavee,

      This is great news indeed!

      What is the best guess about upcoming Quartus release timeframe? I suppose we are talking about 2025.1. Or will it be a something like Quartus 24.3.2?

      Thanks,

      Regards,

    Hello Guerric,


    Apologies for the delayed response.

    I'm not be able to disclose the timeline but most likely in 25.1.1. This is subject to change and not a fixed timeline.


    Hope that answer your query and I'm glad to provide further support if it happened to have further queries. I will go ahead and close the thread and feel free if you've any new queries.


    Regards,
