I've written a matlab code to generate sinewave to that I added noise and then that signal then I converted into text file.
This textfile has decimal floating values. I want to read this file in verilog testbench and get input from that file. and again backto write in another text file the output.
can anybody help me in this?
 

Assuming the file in like :

.1
.12
.15
.2
.26
.3

and so on

write code like this

integer in,i,out;
real data;

initial begin
in = $fopen("input.txt,"rb");
out = $fopen("output","w");

if(!in) $display("File Open Error!");
if(!out) $display("File Open Error!");

i = $fscanf(in,"%f",data);
i = $fwritef(in,"%f",data);
$fclose(in);
$fclose(out);
end
