Re: Xilinx BRAM initialization utility

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.
