Reading an input file using std.textio

rafaelkl

Hi,

I 'm having a problem trying to read an input file on a testbench on Incisive.

I believe the problem is due to a wrong file path, but I tried to copy the file to several folder and none worked.

The line I'm using, which worked in other simulator is:

    file input_file: text is in "test_in.txt";

On Irun command, I obtain the error:

    file input_file: text is in "test_in.txt";

    ncvhdl_p: *E,ILLPRI (../tb/tb_top.vhd, 112|35): expecting an expression or operand [7.1] [7.3].

Any idea what could be the problem?

Thank you!

  • Sorry, I should have posted more of the code.

    I'm using basically this:

    process
        FILE vector_file_in: text IS "test_in.txt";
        VARIABLE input_line : line;
        VARIABLE str_stimulus_in: string(8 DOWNTO 1);

    begin
        WHILE NOT endfile(vector_file_in) LOOP
            readline(vector_file_in, input_line);
            read(input_line, str_stimulus_in);
            -- tests
        end loop;
    end process;

    I am using -v93, so may be this the problem. But Modelsim is also configured to use it and works fine.
    Unfortunately I can only test next week.

    Thanks!

    This compiles without complaint with the -v93 option. It is the extra keyword "in" that is required by the '87 standard and appears in your original example that leads to the ILLPRI error.
