Hi Have anyone modified the PCI files to include the Spartan-III 16Kb RAMB? Is it simply a mather of adding the definitions in the fifo RAM definitions files, plus maybe changing some validations to include RAMB16. Using 16K could lower the RAM block count from 3 to 2 per sides/interfaces (by making 32 or 36-bit wide RAM). And at the same time, used shared RAM while having even more depth than the 4Kb RAM (ex: shared memory having 256 bytes per directions, for a total on only four RAMB used, instead of 128 bytes per directions with 6 RAMB of 4Kb). Spartan-III and Virtex-II are becoming popular, and would be nice to add their native RAMB to the CVS.
