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 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: http://www.xilinx.com/products/design_resources/mem_corner/

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. ---
