Arria 10 with DDR4 Interface

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?.
