I am just trying to test my design in the modelsim simulator.

I have this code in my test bench, the code increment data and drive it to my design.

while ( cnt_loop < 256 ) loop

data_sig <= data_sig + '1' ;

usb_data_out <=usb_data_out +'1';

wait for 10 ns;

cnt_loop := cnt_loop + 1;

Instead of increment data I would like this test bench to pull data from a file.

This way I can make any kind of file. its very comfortable.

Do you know how to do that?
