Memory Support with A5ED065BB32AI4S Agilex5 FPGA

Hi,

I am using the A5ED065BB32AI4S FPGA, Want to connect the DDR4 X32+ECC with the 2A,2B,3A,3B.

We have 512M X16 memory want to interface 4GB with the PS and 4GB with the PL how i can ?

Thanks

Jay

    For the A5ED065BB32AI4S (Agilex 5 E-Series SoC), the HPS EMIF cannot be placed in arbitrary banks such as 2A/2B/3A/3B.

    The HPS DDR interface uses dedicated EMIF resources hard-wired to specific HSIO banks located adjacent to the HPS block.

    Please check the following link for HPS subsystem and bridge system interation.

      Hi,

      Thanks for your reply .

      For PL X32+ECC with the 2A,X32+ECC with the 2B bank.

      For PS X32+ECC with the 3A,X32+ECC with the 3B bank .

      is the above mapping fine?

      Thanks
