Creating Multi Files

OP #4909577 
Im exporting the data to a  file using print but now I need to solve 
this system for different values of my parameters and i dont want to 
create different files manually. Does anyone knows how can I create 
different files to store the different solutions i get for the different 
values of my parameters?

Sorry for my english and thanks!

OP 
I am using VHDL language.

Different data should be write into  different files by creating 
manually...

Below is the equivalent C code. I am not able convert it to VHDL..

FILE *files[numfiles];
for (int i = 0; i < numfiles; i++)
{
    char filename[20];
    sprintf(filename, "results%d.dat", i);
    files[i] = fopen(filename, "w");
}

Here is a starting point:
1
entity multiple_files_tb is

2
end entity multiple_files_tb;

3


4
library std;

5
use std.textio.all;

6


7
architecture testbench of multiple_files_tb is

8


9
    constant filename : string := "results";

10


11
begin

12


13
    main: process

14
        file        outfile : text;

15
        variable    status  : file_open_status;

16
        variable    l       : line;

17
    begin

18
        for index in 0 to 20000 loop

19
            file_open( status,  outfile, filename & integer'image( index) & ".dat", write_mode);

20
            if status = open_ok then

21
                write( l, "this is file nr. " & integer'image( index));

22
                writeline( outfile, l);

23
            else

24
                report "error opening file " & integer'image( index);

25
            end if;

26
            file_close( outfile);

27
        end loop;

28
        wait; -- forever

29
    end process;

30
end architecture testbench;


Text and file processing is no fun in VHDL. I would write everything 
with a tag in a single file.
After that you could any better tool for processing like python, matlab, 
c, you-name-it.

Look there somewhere around page 500:

And there was stefanvhdl.org ...
As a pity its offline now, but with wayback you ca look a captured
