creating .pof file

--- Quote Start ---

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?

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?

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;

Hi,

what kind of strange behaviour did you observe ? Do have timing violations in your design ? Where does the gpio14 signal coming from ( xxMhz?)

Kind regards
