Thanks all, it seems a good idea, but finally I used Tcl, it's quite
simple

Glad you saw the light.
tcl is much better at text than vhdl,
as is python, bash script, emacs-lisp, perl, ...

Hemm... actually I used Tcl just as a macro to be used with modelsim
(as HT-Lab suggested); in my VHDL TextIO is still present, but since I
use the files name as generics, they don't have to be constrained
anymore.

Maybe, as you say, I did better if I used just Tcl or Python or so on,
but I want to take confidence with VHDL for further applications, and
I had data from an actual detector already stored in .txt files.
Anyway I think it's nice to know how TextIO works because, even if
it's not very powerful, it gives you the chance to understeand how an
hardware model would work on data already stored; and I don't think
this is a so rare application.

Sorry that I misinterpreted your posting.
Congratulations for conquering textio.

I prefer to convert existing text files to vhdl packages
using a scripting language, since I am using one anyway
to run modelsim. This isn't better, just different.

Hi all,
I'm new in vhdl and I want to read from a file which contain numbers
separated by POINT not by White space ( as the textio procedure works by default ), it's like this
44.123.25.254
44.123.25.253
44.123.25.250

I wanna to compare such line withe an other variable like this

entity start is

generic( File_string : string := "C:\IP\IP.txt" );

port(
in : in std_logic_vector(32 downto 0)
);

end entity

archtecture arch of start is

signal L :std_logic_vector(32 downto 0);
begin
P : process


FILE inFile : TEXT IS IN File_string;

VARIABLE inLine : LINE;

begin
****
****
****




Can you tell me how can I do to compare the Input value with such line
with READLINE
Are we obligated to peass by READ after READLINE or a simple READLINE it's enought?
thx..
