Contributorwill 64bit EMIF works with a 72 bits DDR4
Dear Inter support and expert
I am porting a TI demo to Arria GX development board, the original design was a 64bits EMIF. and the DDR module is 72 bits.
to make it simple, I hope I can use 64 ...
Hi David,
In case you're doing some demos, I think it's good for you to create an EMIF example design with Arria 10 Dev Kit preset where you can choose the preset in the EMIF Parameter Editor.
The preset will set the parameter that match to the Arria 10 Dev Kit.
The 72 bits = 64 bits Data + 8 bits ECC.
If you enabled the ECC in your configuration, then you will have 72 bits interface.
Else your interface should be 64 bits.
