3D RAM EMIF IP support

Hello. Making a duplicate of the topic based on this one. We are currently using Intel Arria 10 FPGA for our projects. For designing and programming it we have Quartus Prime Pro v21.1.0 B...

    Hi Mark,


    Yes sure I can share an example design with 3DS EMIF interface targeting Stratix 10 device.


    It's unfortunate that the 3DS device does not support in Arria 10. The hard memory controller does not support 3DS and Chip ID bits.


    Regards,

    Adzim

Hi Mark,


Does the "3D RAM" here give a same meaning to 3D stacked die?

For Arria 10 device, the 3D stacked die is not supported by the EMIF memory controller.

This feature is only available in Stratix 10 and Agilex 7 devices.


The memory density is possible for 128GB because the memory controller can support data width up to 144bits and 4 ranks.


You may refer to this link for features available in Arria 10 EMIF memory controller: https://www.intel.com/content/www/us/en/docs/programmable/683106/21-1-19-2-0/hard-memory-controller-features.html


Regards,

Adzim

    Hello Adzim,

    I apologize for a delayed answer.

    Could you provide an example project with 3D stacked die EMIF either for Stratix 10 or Agilex 7?

    Best regards,

    Mark

      In addition to my message above, is there a possibility(workaround) available for Arria 10 to use 3DS EMIF IP?
