how to use the design results of the vhdl code for a program in C code

Started by lolita grenoble March 15, 2010
hello,
i need help.
i work over an algo in C langage that verifies a design described in
VHDL
for it, i want take all informations from my vhdl code for use them in
my programme in C and i don't know how.

One way is to write a file in your VHDL code (running it in the simulator) then read that file in your C code. - Brian

Indeed. You can write binary files (e.g. .bmp images) from VHDL but the details are not defined so the result is not necessarily portable. Modelsim is straightforward but Xilinx ISE Simulator is not. - Brian
