Need help implementing a proj on SPARTAN3

[Riccardo Fregonese]

Hello, I'm Ricky, an Italian student in eln eng.
I'm working with a Xilinx Spartan3, I've designed a project that
calculate a 12bit fft. The core reads data (in serial mode) from the
ISSI 1M RAM block, calculates the fft, and then writes the results in
an other zone of the memory.
My problem is to put the initial data into the memory (from my pc) and
read them at the end, to verify if the fft works!
I knew that XESS corp. provides programs for their boards that permit
to easily download and upload data to/from the RAM, but what about
DIGILENT-XILINX boards?
Do you know if there's a program that could help me?

Please, help me, I'm working on a thesis, and I have no more
time!!!....
Heeeeelp!!!

Hi Ricky,
i used the configuration PROM of the Digilent board to store my data as
described in XAPP 694. After startup i copied the content of the serial PROM
into the SRAM.

I can mail you the VHDL source of the statemachine for this copy operation.

Regards

Thomas

Xilinx have a tool called Data2Mem (I think, it might be Data2Bram)
which allows you to set the contents of block rams by directly
manipulating the .bit file
