ML402 DDR SDRAM

Started by Jered November 7, 2005
Has anyone been able to get the ML402's DDR SDRAM running with a
MIG-generated DDR controller, as opposed to the EDK PLB DDR controller?
 Xilinx is unable to confirm this works... there's a thread in this
group from July with some ML401 MIG questions, but no resolution.  My
group is interested in using the 402 in a non-SoC application, so we're
sort of wondering if MIG has been proven here.  Thanks!

Hi, Jered, I tried months before to use MIG007 generating a DDR controller for ML310, failed and the xilinx support did not help to get through. I modified everything to fit ml310 kit and when I download the generated testbench, nothing happened in the DDR. You can discuss with me by: xjf77(at)yahoo.com. regards

I am running MIG DDR rel6 on the ML310. You need to work around to connect rst_dqs_div_in and rst_dqs_div_out outside of FPGA.

Hi, all, I forgot to tell you guys something. MIG DDR support only unbuffered DIMM as far as I know. The DIMM coming with ML310 is buffered DIMM. In my case, I replaced DIMM and it works fine.
