Hi I want to read data from a ddr3 sdram. I'm using vivado. my memory model is M471B2873FHS which is not mentioned in the "xilinx memory interface generator". what should I do? thanks. ( I apologize for my bad English ).
You need a memory I/F within your FPGA. Unless you want to write it by yourself, you can use the memory I/F IP (MIG) from the IP Catalog. As an intro, see: https://www.youtube.com/watch?v=wqaGBvQwyRc

Hi Hamid, Xilinx Memory Interface Generator simply initialize some Timing Values by selecting a Memoy in the generation process. You should be able to compare the data from the datasheet with Micron Memories which should be avaiable and select the complementary part...

I have a video board and need dual port access to a ddr sdram. I also launched MIG to obtain a DDR3 Controller for my given design. I have experience with DDR2 and DDR3 and am also familiar with the MIG. Surprisingly the MIG does not offer a multi port option anymore for current devices unlike it used to be before when I designed for spartan 3 e.g. Anybody can help with this issue? in the Xilinx Forum it is discussed to use a AXI based design or create a round robin controller myself. anybody did this?

Please don't capture this thread but open your own. Regards BigChip
