Agilex 5 SSGDMA Example Design Generation Failed

Hello,

It seems I'm having an issue generating the example design for the Scalable Scatter-Gather DMA IP in PCIe mode (for Agilex 5 A5ED065BB32AE4SR0) in Quartus Prime Pro version 25.1 running on Windows 10 Pro.

I’ve followed the instructions on generating the example design found here. Regarding the IP parameters, I was sure to match the number of H2D ST ports and D2H ST ports (1 each), and I only created 1 H2D MM port. I did not enable the BAM interface and I kept the application interface as 128-bit.

When attempting to generate the example design, the system begins to generate it (takes about 5 minutes) but fails when copying a file to the temp director in AppData. I've attached the output from the generate example design screen. The error can be found on line 32.

Is this a known issue in Quartus 25.1? I can attach my complete IP parameters if required.

Thank you!

    I am seeing the same issue from myside.

    I have filed a case to the tool specialist to investigate on this.

    This issue seem to be occur in Window OS machine due to the path length limitation in windows -- Windows OS supports file path up to 260 characters by default. Window OS do support longer paths with the proper registry configuration as described in the KDB below.

    https://www.intel.com/content/www/us/en/support/programmable/articles/000075424.html

    Please try to enable the long paths stated in the KDB and see if the issue persists.

      Hi Richard,

      Thanks for getting back to me! I checked the registry on my Windows 10 Pro computer and it seems the LongPathsEnabled key is already enabled. Unfortunately, I'm still having the same issue.

    Could you check whether setting H2D MM to 0 allows you to generate the example design?

    Please try this with the following configurations:

    (1) Long Path Enabled
    (2) Long Path Disabled

    Do you observe whether the same issue occurs with (2), using H2D MM -> 0 , but the example design is generated successfully when (1) is enabled?

    Regards,

      Richard,

      Here are the results from testing:

      Long Paths Enabled, H2D MM = 0 -> Design example generation fails

      Long Paths Enabled, H2D MM = 1 -> Design example generation fails

      I was unable to disable long paths in the registry editor as I don't have permission to modify the registry. Would you suggest using Quartus in a Linux Virtual Machine to generate the design example?

    Yes, there is no issue in generating the example design in Linux OS.

    Hi Richard,

    I was able to generate the design example using Linux. Thank you for your help!
