Arria 10 External Memory Interface Pin Infromation

Hi,

I am using MT41K256M16HA-125 IT:E DDR3 Interface with 10AS016E4F29ISG SoC.

I had downloaded external memory interface information pin information file and pin out file. I need some clarifications regarding external memory interface.

From the EMI pin information,

1) which scheme i need to follow (Schemes like 1/2/3/4/5) ?

2) only pin mapping of address and control lines are given. Could u please suggest a suitable pin mapping scheme for Data Mask, Strobe and Data lines.

3) From the pin out file, is there any relevance for DQS for X4 / X8/9 etc..in EMI.

Thanks,

Ninan Mathew
