    Default creating .pof file

    Hi all,
    I am using a CycloneIII FPGA. When I compile my design, only a .sof file is created but not a .pof file. What should I configure in order to create a .pof file (for Active Serial Programming)?

    Thanks,
    Dvido

    Hi Dvido,

    you can convert the sof to a pof file. Open Quartus and choose:

    File -> Convert Programming Files

    Kind regards

    Actually I noticed that it's a part of a bigger problem.
    As I understand, these files are supposed to be created by default. Except that, when I compile a design, sometimes the compiler won't give me an error on some basic things, like wrong vector size (things that would always result with a compilation error). I re-installed QuartusII but it didn't help. Any ideas?

    Default creating .pof and sof files

    Dear Divdo and others
    Greetings
    May I ask for your help, please? I am compiling my design by using Cyclone II. The compilation was successfully done and yet to get .pof and .sof files. Kindly advise me what I should do?

    Regards

    Hi Dvido,

    did Quartus finished succesfully or not ? Maybe you can post an example here ?

    Kind regards

    It did, though it had a problem with one of the files (don't remember which one) so I deleted all the compilation files and re-compiled. Also when I burn it it works fine. I converted the files like you suggested.
    I still think that I have a problem since these files aren't generated automatically and the compiler acts a little strange (as I described earlier).

    Hi,

    that means all is up and running now?

    I am able to compile but I still have these strange issues with the .pof files not being created and some errors not being reported by the compiler.

    Ok,

    when using a pof file you need a configuration device. In the Quartus default settings the
    generation of prog files for the configuration device is disabled ( I don't know why ??).
    You can change the setting by:

    Assignments -> Device -> Device and Pin Options ... -> configuration

    Switch on "Use Configuration Device" and select your configuration device.

    For your other problem, can you post an example ?

    Kind regards

    Here is an example of the strange behavior: bellow you can find a very simple process. It didn't work yesterday but its working today, though I haven't changed anything.

    handshake : process (rst,gpio14)
    begin
    if (rst = '0') then
    start_handshake_fsm <= '0';
    temp_counter <= (others => '0');
    elsif (gpio14'event and gpio14 = '1') then
    if (temp_counter < "1000") then
    temp_counter <= temp_counter + '1';
    start_handshake_fsm <= '0';
    elsif (temp_counter = "1000") then
    temp_counter <= temp_counter;
    start_handshake_fsm <= '1';
    end if;
    end if;
    end process handshake;
