I'm planning to use Spartan 3e and SDRAM for a product - sort of a simple video "card" for an embedded CPU system.
I got myself the Spartan 3e STARTER kit and I'm trying to use the SDRAM on board. Found the MIG 1.6 and the pre-configured "bl2cl2" set of files. Got them to synthesize by editing a full (wrong for me) path to "params" file. So far so good. Changed the UCF to use the 50 MHz clock rather than the external one. The resulting bit file loads and does*something*. At least there are pulses on "data valid" LED.
I may get somewhere if I continue on this path but it will take me a long time to figure out how this core works.
I wonder if anyone knows of an existing design that uses SDRAM on this board interfaced to something: soft CPU, video generator, etc.
