SImple "C code" == complex simulink model?

Hi,

There is very simple c code of "some" modulator.

     if((PID_sum > CONST)) {
        //Period const.
        periood = MIN_PERIOOD;     

        impulls = ((unsigned int32)PID_sum* MIN_PERIOOD)/10000;  // /10000
     }
     else {                                                                              
        //Impulls const.
        impulls = MIN_IMPULLS;

        periood = (unsigned int32)(MIN_IMPULLS * 10000) / PID_sum;
     }

This code must be executed every time period counter ends and new period- and impulse duration will be calculated from code above.

There is my result in simulink:

God! It looks huge right?

I used some const variables that were declared in workspace used to- & from workspace blocks. Could be done without thease workspace transformations.

But it is "author of this thread" stuff... a almost first simulink "thing" he had done. Not good right. Problems with "from workspace" block init values.. fist thing that comes up. not scalable. + fixed time 0.1 which ist well suited to bigget variable time model.

How would you do it? Is it possbile to use somekind of mathalab functions simulink block. Or... can i have use c code? worth it? Or simulink block is the way to go. Just "to do" better solution?

Thank you in advance!
