Xilinx BRAM initialization utility

[Muhammad Bilal]

Hello all, I have recently developed a minimal configuration OR1K CPU  
and the GNU Toolchain. I wrote a tiny utility in C++ that generates  
the Verilog Code for BRAM initialization in Xilinx ISE. It takes in  
the object file generated by 'or32-elf-objcopy' and outputs the  
verilog file. It works fine for me but it is much less flexible than  
the professional Data2Mem from Xilinx. Has anybody done anything  
related? If anybody needs the source code, I can email.

regards
Bilal

Good day Bilal,

      I would truly appreciate the source code of the BRAM initialization
utility you wrote.

Thank you,
Vincent

Hello,

  Attached I send the utils I use to generate a .coe file for BRAM
initialization on Xilinx FPGAs and a example Makefile where you can see how
to use them. The bin2hex converts the output of or32-elf-objcopy tool to a
hex file, this tool was taken from or1k cvs. The other tool was written by
me and takes the hex file and creates the coe file you can directly use in
the coregent tool.

I hope it helps

Regards

Hi! I've been using srec2vram tool from from das-labor. Its been developed by Joerg Bornschein and can be found at https://roulette.das-labor.org/bzrtrac/browser/fpga/soc-lm32/soc-lm32/tools/srec2vram

It has worked in my openrisc testbench for Icarus Verilog.

If you want to populate the BRAM contents on your bitstream file have a look at Openfire documentation.

Hope it helps.

Kind regards,
José Ignacio Villar.
