Hi Avinash,

Thank you for reaching us to help you with this issue.

I'm Eliath Guzman and I'm going to help you with it.

I can see in the link of the reference design you are working with, use Quartus version 16.0.0 standard, is the one you're using, the same version or it is a newer version?

Regards,

    Hello Eliath,

    So, Initially, we tried using the reference design for 16.0 in Quartus 16.0. We got many errors as shown in the screenshot.

    When we tried the same reference design in later versions of Quartus i.e. 17.1 and 18.1, some of the errors have been reduced and other errors have appeared related to SGDMA IP used in the ethernet system qsys. The ELF file was not generated. I am attaching the screenshot.

    So, we got an assistance from a Field Applications Engineer from Intel, where he gave us a new project in which the SGDMA was removed and replaced by MSGDMA. By this, the ELF file was generated. But when we are trying to establish the communication, AUTO NEGOTIATION FAILED error is popping up. I am attaching a screenshot for this.

    Even the reference design does not contain the required main sdc file i.e niosii_ethernet_standard_5CGTFD9E.sdc file to do the timing analysis. I feel that the design present in the website needs a major overhaul to make it working. Kindly help us. We are stuck with this issue for the past 2 months.

    Regards,

    Avinash
