why it is recommended to connect EMIF in single column??

[hb0001]

What is the purpose or reason for the below mentioned comment

"Ensure that the pins of a single external memory interface reside within a single

I/O column"???

HI,

You can refer to below EMIF user guide doc page 15 to learn more about IO column and IO bank architecture.

• https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-20115.pdf

Basically single memory interface is formed by using IO pins from adjacent IO_bank within one IO_column only

You can't use IO pins from different IO_column due to architecture wise IO_column is independent entity.

• There is no physical connection to link IO pins from different IO_column together

I hope I clear your doubt now

Thanks.

HI,

I don't hear back from you after my feedback explanation.

Hopefully I clear your doubt.

For now, I am setting this case to closure.

Thanks.
