Re: reading an array of parallel input data

This is what I am using right now and I get the errors

Error at 30.000 ns(1): Textio read:: called on empty string or line
at 30.000 ns(1): Error: Oops, bad separator
this continues upto 100 ns.

even if I do not use the clock, I get the same errors. I have checked
the simulation in modelsim without the testbench that gives correct
result.


ReadAndApply: process
    variable c: character;
    variable i: integer;
    variable L: line;
  begin
    file_open(StimCSV, "StimCSV.csv", READ_MODE);
    while not endfile(StimCSV) loop
      wait until(clk'event and clk = '1') and reset2 ='1';
      readline(StimCSV, L);   -- Get the next stimulus line
      for j in stimulus'range loop
        read(L, i);    -- Get the next integer
        if j /= stimulus'right then
          -- it's not the last item; skip the next comma
          read(L, c);
          assert c = ',' re****t "Oops, bad separator";
        end if;
        stimulus(j) <= std_logic_vector(
                          to_unsigned(i, word10'length));
      end loop;
    din<= stimulus;
    end loop;
    file_close(StimCSV);
    wait for 20 ns;
    wait;
  end process;
