Can't find Agilex 7 M I/O PLL Reconfiguration Design Example

Hi,
Recently updated document
"Agilex™ 7 Clocking and PLL User Guide M-Series", 769001   2025.10.09
refers to a design example which uses an EMIF Calibration IP for I/O PLL reconfiguration:
6.1.7. Design Example for I/O PLL Reconfiguration

I can't find this design on Intel or Altera sites. Can anyone please tell if it exists. I can find very similar Agilex 7 PLL reconfig examples but they use different calibration IP, not usable with Agilex 7M devices.

I'm trying to utilize IOPLL's dynamic output phase adjustment only. This was easy with earlier generation devices as the I/O PLL provided a specific control interface for this purpose. Phase shift control port or something similar.

Thanks,
Ju-ti

    Hello,

     

    I have an update to share with you,

    I have the access to the early version of this design example which have validated through simulation.

     

    Kindly let me know if you want me to send it to you.

      Hi Aqid,
      Yes, I'm interested in early version, but I could wait for the published version as well because I worked around the need for adjustment this time. I will need it for another purpose later.
      Thank you for follow up.

      Hi Aqid,
      Yes, 791087 is one of those which I mean. Now I noticed that two others, IDs 763982 and 714741 are earlier versions of 791087.
      And yes the latest one, 791087, seems to be for Quartus 23.3. However the new document 769001 ( Agilex™ 7 Clocking and PLL User Guide M-Series ) that refers to an example has been updated for Quartus 25.1.1.

        I just want to update you that I already escalate your concern to the apropriate team. Let's see if we can get the design example mentioned in the document.

         

        I really appreciate your patience.
