Intel Arria 10 with dual-rank UDIMM EMIF

Hello. I am a newbie in developing software for Intel Arria 10 FPGA. I have a PCB with installed FPGA and trying to use EMIF. Unfortunately, I got an error on calibration stage. After some timing...

    Hello Mark,

    I have attached the example design in .qar file below. Please let me know if this design can fit into your board.
    Please share the Report DDR as snapshot below after the compilation process.

Hello Mark,


The Arria 10 device can support DDR4 memory device with UDIMM memory format , up to 2 DIMM per channel , up to 4 Rank topologies.

You can check the details with EMIF Spec Estimator in this link: https://www.intel.com/content/www/us/en/support/programmable/support-resources/support-centers/emif-spec-estimator.html


I can help to check the EMIF IP configuration based on the memory device datasheet.

Can you share the memory device datasheet that you are using and also some snapshots of the EMIF IP?


Thanks & Regards,

Adzim

Hello.

Currently I am using the following memories:

Kingston KVR26N19D8/16 Samsung K4A8G085WE-BCWE 16 GB 2666 UDIMM 2Rx8 Non-ECC
SK hynix HMA82GU6AFR8N-UH SK hynix H5AN8G8NAFR-UHC 16 GB 2400 UDIMM 2Rx8 Non-ECC

Here are manuals from memory manufacturer:
https://www.memory-distributor.com/pub/media/downloads/datasheets/K4A8Gxx5WC.pdf
https://download.datasheets.com/pdfs/2017/11/3/5/12/58/809/hyn_/manual/h5an8g6nafr-vkc.pdf

So far, I have reached pretty good marging, but it started to fail write leveling after 2nd group.

Attaching zip archive with calibration results and EMIF parameters.
