New ContributorError : Arria 10 emif_reset_ interrupt acknowledge
Hi All,
I am currently working with an Arria 10 FPGA on a custom board and have encountered an issue where the PCB restarts after the following error message appears:
"Error: Arria 10 EMIF reset interrupt acknowledge"
I have verified all supply voltages and clock signals, and they are within the expected ranges. Initially suspecting a DDR-related issue, I replaced the DDR component; however, the problem persists. Additionally, all status pins appear to be functioning as expected.
I would appreciate any guidance or suggestions on how to further debug this issue.
Thank you in advance for your support.

Hi SUHAS_KRISHNA,
I would suggest to check the DDR component with the EMIF Example Design.
You may refer to user guide to generate the example design from the link: https://docs.altera.com/r/docs/683842/21.1/external-memory-interfaces-arria-10-fpga-ip-design-example-user-guide/generating-the-synthesizable-emif-design-example
Please enable the EMIF Debug Toolkit as following instruction to check the calibration details of the DDR: https://docs.altera.com/r/docs/683106/current/configuring-your-emif-ip-for-use-with-the-debug-toolkit

SUHAS_KRISHNAHi ,
The problem is that we have fabricated and assembled 4 PCB, of which 3 are working fine in the 4th one I'm facing this issue, kindly guide me in debugging or what critical points that should be checked.

Hi SUHAS_KRISHNA ,
Please help to verify the DDR component with EMIF example design on the failure board.
Gather the calibration report and share it here for more details.
