Stratix 10 MX Development Kit - Low Latency 100G IP Core Design Example Problems

Hi,

I am using the Stratix 10 MX (8 Gb) Development Board (Device: 1SM21BHU2F53E2VG) to test out the Low Latency 100G Ethernet Intel Stratix 10 FPGA IP Design Example on Quartus v19.1.

I have reached step 1.8 in the design example user guide successfully, but I am getting a very weird results to no results. I have no idea why the IP core is not working as intended. I have attached the .qsf file, the System Console output, and the Ethernet link screenshots.

IP Core User Guide: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_s10_ll_100gbe.pdf

Design Example User Guide: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-dex-s10-ll-100gbe.pdf

Thank you.

      Hi Sengkok,

      Thanks for pointing the incorrect pin assignment out!

      Unfortunately, I am having the same poor results where nothing appears to be working. I have attached the updated qsf file.

      Thanks,

      Lars

    Hi Lars,


    You may check turn on the Internal serial loopback for this design example. If this is not working, then I suspect there might be something wrong with your clock source or pin assignment.

      Hi SengKok,

      You were correct, it was a pin assignment problem. When I moved the clock pin from AG43 or CHT to AJ43 or CHB it started working.

      Thanks for your help!
