    first thing i used mig, so i could help you, second is did what you
    want, Third you will have some problems 8-)
    The first thing to do with code generated by mig is check all the
    connections and pin type generated, i remember that mig generate one
    data-bus signals between buffers and a top interface have a path
    changed, must bu output and mig generate as input, check all of this
    first than your code will synthesize. Always when i had problem with mig
    in 2004 was this the problem, was one signal specifically, unfortunately
    i forgot what is the signal name 8-( .

    | Hi all!
    | Curently I am a Master student and I am working on my master thesis.
    | And for some purposes I have to write or adapt a DDR SDRAM memory
    | controller (for Xilinx Virtex II board with xc2v4000 FPGA). First I
    | wanted to adapt DDR SDRAM memory controller from opencores projects
    | but there is no support and noone ansers questions:( Then I found the
    | Memory Interface Generator (mig007) tool from Xilinx and generated a
    | memory interfece. Unfortunatelly I have lots of errors during
    | translation (in ucf file after I defined all pins acording to my board
    | ucf file). I asked Xilinx but there is no answer. I do not know what
    | to do. Could someone help me? I would be glad to have any help.

    | Best,
    | Anna
