Need DDR SDRAM controller for Xilinx Virtex II or Spartan 3 FPGA

[javad]

Hi all,
I'm looking for a free good controller core for micron ddr sdram "mt46v16m16" to be implemented on xilinx virtex2 or spartan3 FPGA.
I would be pleased if you help me to find that.
If this core supports burst lenght = 8 and bidirectional DQS signal, it's much better for me.
Thanks.

See the link below this one is from opencores!

Hope this helps!

OK! But It only supports Burst_Length = 2 and provides unidirectional DQS.

use MIG1.5 From Xilinx

it's a your answer.

Re: DDR SDRAM CONTROLLER

why not try sdr ... as its also a better option ... relatively more easy and u can get more information on that easily ...

but i feel for ddr , u have to do it urself ... as i was also needing it in my recent project but due to relatively less info ... i shifted to 32 MB sdr sdram of hitachi and micron ....

one more thing ... r u using DIMM or SIMM or a simple chip .... as i m talking about DIMM ...
