    Hello,


    Thank you for using Intel Community.

    I am Adzim, application engineer will help you on this topic.


    The ddr3 interface required the Vref connection for the data pins only.

    You should refer to Quartus compilation report on which IO bank that required the Vref connection.


    "Can I use internal Vref voltage reference ?"

    • Yes you should be able to use that.


    Regards,

    Adzim
