Hi Greg,


Thank you for providing the pin assignment.

  • The pins are placed at HPS EMIF IP.
  • Calibration is successful at this pin assignment and with IP timing parameter.
    • Can you provide the EMIF IP setting from the Parameter Editor GUI?
    • Please provide the memory datasheet as well for checking purpose.

  2. Is there any timing violation occurred after compiling the design?
  3. May I know which Quartus version and OS environment that you used?


Thanks!

Regards,

Adzim
