DDR3 - CYCLONE V SOC FAILING ON HARDWARE

We have designed a hardware in which we have developed three boards using CYCLONE V SOC using DDR3 - 8Gb [3 numbers on every board] . In this we have found that 2 hardwares are working perfectly fine...

Hi NAli1,

Does your suggestion work on the HPS side of the Cyclone V SOC as well.

My failure is HPS side DDR3 interface which is working on remaining 6 boards.

Thanks

    Hi MHada,

    I'm sorry that I misunderstood your issue at the first place.

    Let me try to re-explain the issue again to make sure that we are on same page:

    • You are having three boards using CYCLONE V SOC using DDR3 - 8Gb [3 numbers on every board].
    • 1 out of 3 boards having calibration failure.
    • Replaced all three DDR3 but still facing the issue.

    If the above understanding is correct, then seems like there is no issue with the IP since the DDR3 is working fine with the other boards. If it is having issue, then high possibility it will also failed in the other 2 boards.

    I see this is regarding board to board variation. Please re-check all the board setting and connection. If it is good, high possibility the issue is due to the FPGA side. I suggest you to contact your sales FAE and proceed for ERMA process.

    Thanks

    Regards,
