Agilex 5 SSGDMA Example Design Generation Failed - 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! Replies: Re: Agilex 5 SSGDMA Example Design Generation Failed Hi Richard, I was able to generate the design example using Linux. Thank you for your help!

Regards, Richard Tan Replies: Re: Agilex 5 SSGDMA Example Design Generation Failed Yes, there is no issue in generating the example design in Linux OS. Regards, Richard Tan Replies: Re: Agilex 5 SSGDMA Example Design Generation Failed 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? Replies: Re: Agilex 5 SSGDMA Example Design Generation Failed 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 Tan Replies: Re: Agilex 5 SSGDMA Example Design Generation Failed 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. Replies: Re: Agilex 5 SSGDMA Example Design Generation Failed 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. Regards, Richard Tan Replies: Re: Agilex 5 SSGDMA Example Design Generation Failed I am seeing the same issue from myside. I have filed a case to the tool specialist to investigate on this.
