Hi In order to connect a DDR memory component (not the DIMM) to spartan-3 - Is it better to use DCI on spartan-3 pins ? If so is there an example ? - What sort of termination is required at the memory end. - Is there a reference schemetic ? Thanks Sumit

I've build my own controller on base of that in XAPP and it works fairly well at 266 MHz.

Sumit, Check out Application XAPP768c "Interfacing Spartan�3 Devices With 166 MHz or 333 Mb/s DDR SDRAM Memories" which can be accessed after registering for it on: http://www.xilinx.com/memory Cheers, Shalin- do_not_reply_to_this_addr@yahoo.com wrote:> Hi > > In order to connect a DDR memory component (not the DIMM) to spartan-3 > > - Is it better to use DCI on spartan-3 pins ?
