Arria 10 with DDR4 Interface

[Indumathi]

Hi Team,

We are designing a board with  Arria 10 Part Number -10AX057N2F40E2SG   with DDR 4 Interface

Can you help us to clarify the following queries to ease our design process?

Question1 --> Can above Arria 10 part number support a 64-bit dual-channel data bus with Hard IP? 

Question2 -->  If Dual-channel DDR4 64 bit Hard IP is not supported how to implement it? As the datasheet says it supports  X144 bit

Question 3 --> In EMIF DatasheetSection 3.7 Page 47-48  Note: Notes to table:
1. Only Intel Arria 10 devices with a special ordering code support 64-bit and 72-bit data widths; all other devices support 
only to 32-bit data widths   --> Can you clarify if the part number[10AX057N2F40E2SG] supports 64 bit?.

Hi

There is useful page on Intel web site to check EMIF spec meets your device.

https://www.intel.com/content/www/us/en/programmable/support/support-resources/support-centers/external-memory-interfaces-support.html

1.  When I check the EMIF Device selector 10AX057N2F40E2SG support two DDR4 64bit interfaces.

2.  Your device support two DDR4 64 bit interfaces.

3.  Your device support 64bit DDR4 interfaces.

Hi Team,

Can you clarify if the device support two DDR4 64-bit interfaces it is soft ip or hard ip?

two DDR4 64-bit interfaces is hard IP
