    Nexys4 DDR & MIG

    Thanks a lot! I missed that. I need to provide the 200 MHz clock to the sys_ck and the ref_ck use system clock. Again, thanks for the answer. regards, Pedro

    Nexys4 DDR & MIG

    Hi, I am trying to understand how to generate a MIG based memory controller in the Nexys4 DDR board, I am reading the UG586 (Memory Interface Solutions), but I am not sure about the system clock and the reference clock. Should I mark them as "no buffer" in the GUI and connect them in the top level source with a 200MHz clock to both of them? Thanks in advance for your help best regards, Pedro
