Hi Himanshu,

Greetings.

I am first wondering how you succeeded to have the sdram controller in the platform designer. Please what version of Quartus are you using? I am using here Quartus Prime 22.1.2 standard edition (the latest version) there’s no more the “sdram controller” in the platform designer.

So I wanted also to make one of my designs that is using nios II running in nios-v through external sdram but I got stuck on adding the sdram controller in qsys because it is missing.

Please any assistance.

Thanks

    Hi,

    I know that SDRAM Controller IP is no more supported in the latest Quartus Versions. But I would like to inform you that I have the .TCL file that will generate source of SDRAM Controller IP and it's path is added in the user_components.ipx file. The .TCL will show the SDRAM Controller IP in the QSYS system. It is an older version of SDRAM Controller IP which I am using.

    The SDRAM Controller IP, which I am using is from older Quartus 18.x version. To use in the latest Quartus Versions, we need to add the .TCL file in the IP_IPX_PATH variable which have file user_components.ipx.

    You can ask INTEL to provide the TCL of the SDRAM Controller IP,

    Regards,
