access to DDR on Spartan 3E Starter Kit

[keitheda]

I have Xilinx's Spartan 3e Starter Kit which has onboard DDR memory.

I'd like to start using that memory, but have struggled to get a DDR controller working.

I've tried using Xilinx's Memory Interface Generator, and while the code compiles, the testbench is too complicated & requires an external function generator (which I do not have access to) and/or non-free chipscope. The interface is daunting to someone new to FPGAs as well.

I've also tried various ddr controllers at opencores --- most I can't get to compile.

Thanks

Keith

oh, it's difficultl unless you are experienced in RTLs and hardware design. In FPGA arena, codes don't usually run out of the box like open source software.

use the DDR core for www.gaisler.com

do you use MIG007, I am doing with MIG007 and I am doing behavior simulation
