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