Hi Pavel,

Could you attach the SCL file, so that it might show us what could be the
problem.

BTW: SCL is a quite powerful language actually that is not documented by
Microchip. Usually I found easier to write the SCL file by a text editor or
even better, convert a WAV file into an SCL using a small dirty tool I wrote
-- it looks something like this:

//
// PWM_strait_1.5.SCL
// Generated by WAV2SCL.PL
// Thu Jan  1 00:00:00 1970
//
configuration for "pic12f675" is
end configuration;

testbench for "pic12f675" is
begin
    process is
        begin
        report "Stimulus actions INIT GP3 to LOW for 2ms";
        GP3 <=3D '0';
        wait for 2 ms;

                loop
                        // overall of 22 ms frame rate

                        report "STATE:HIGH for 1.5ms";
                        GP3 <=3D '1';
                        wait for 1.5 ms;

                        report "STATE:LOW for 20.5ms";
                        GP3 <=3D '0';
                        wait for  20.5 ms;

                end loop;
    end process;
end testbench;

Change the processor type for that you have, and pin names etc to whatever
that processor uses, then 'ms' to 's' or 'us' accordingly, basically that's
it...
