Spartan 3E starter kit DDR SDRAM

Started by fpgauser August 2, 2007
I am relying to the older "Spartan 3E starter kit DDR SDRAM code
Options" thread.

Is there such a demo out, mentioned in the thread?

I read in several groups that it is a problem to get this DDR Ram
running ?

I'm not sure what you're refering to, but David Ashley ported the OpenCore DDR SDRAM controller to the Spartan-3E500 start kit and posted it here. I only had to adjust the .ucf file a bit to get it on the Spartan-3E1600 Starter kit. Tommy
I should probably add: More information on MIG can be found on the
Memory Corner on xilinx.com:

Looks like my first message was not posted correctly: The Xilinx Memory Interface Generator (MIG) generates ready-to-use HDL for the Spartan-3E Startker Kit. Cheers, Jaco
Aha! So two chances to get a controller. Will try this ! Thanks to
both of you!

I downloaded the reference design but did only find verilog files which i cannot use. the re also ssems to be an ngc file missing, which is nowhere in the zip archiv. Isn't there a working project for ISE 8/9 which directly compiles and produces some test ? ---- Concerning the other design: I found the .../dash/ocddr design. This is one file, which I do not know how to handle. I had been able to seperate the files, but appart from the fact, that there is a reset module missing, (and a debris of a vga module) I do not know how to start with it and where. ISE imports it an dshows the hirarchy but this is all. ---
