For the life of me, I cannot find the document that describes byte-write limitations in Arria 10 DDR3 hard ip emif. I'm looking for the table that describes how the DM lines can and cannot be grouped in a x64 interface. Thank you.

Hi Sir,

Basically the concept is the same for 256 bits. If you need to write full data the set all the byte enable to '1' . It depends on which data you want to write. I demonstrate it in below table for example.

Thanks.
