Reading a file content with quartus

[Altera_Forum]

Hi everybody, 

 I need to read a value from an external file at compilation time and I don´t achieve to do it with quartus. The same code works for Xilinx Ise but I´m not able to do it with Quartus. The code also works fine with Modelsim.  I have made many changes at code and search solutions on the web but nothing.  This is the begining of the function I use to read the content of the file   -------------------------------------------------------------------------------  -------------------------------------------------------------------------------  use std.textio.all;  -------------------------------------------------------------------------------  -- function to get version from 'version.txt' file    impure function get_version return std_logic_vector is    file data_file: text open READ_MODE is "version.txt";  variable rd_line : line;   begin    -- check that file is not empty  assert(not endfile(data_file))  report "*** ERROR: File is empty" severity error;  -- read 1st line and convert it to string  readline(vers_file, rd_line);  .................................................  .................................................  .................................................  ................................................. end get_version;   -------------------------------------------------------------------------------  -------------------------------------------------------------------------------  The problem is that I don´t get to read or locate the file. At compilation time it doesn't give me the report error but I know that it does't correctly read the file because if I put a file name it doesn´t exist, It seems to do the same (nothing).  I have been searching for any example, but I didn´t found it. Can anyone help me?

Quartus does not support textio during synthesis whilst Xilinx does. I opened an enhancement request for this about 8 years ago, but still no Textio. 

You can get quartus to read in text files using TCL and output a VHDL package that contains the version number.

I will try to do what you said but I need to do it automatically, so I will try to do a script that firstly generates the VHDL pakage and then compiles and generates all the quartus Project. I hope it is posible.
