Hi


May I see your DDR3 IP setting from the GUI?

You can provide the snapshot of the IP GUI and put it in this forum.


Can you share the calibration report from the memory toolkit for calibration fail?

You can generate the report by clicking on Generate All Report in the toolkit.


Thanks,

Adzim

    Thank you for replying to me

    this is my project

    The hardware was drawn by my colleague, and the control lines are not of equal length. The others are of equal length. Currently, I don't know if it's a hardware or software issue. How can I debug to see the timing of DDR3 operation
