How to extract the block execution order using matlab script?

I would like to extract the block execution order from the model. I have to use the block execution order information for other evaluation purpose.

There are a variety of possible definitions for "the model". Could you edit the question and add some more details?

It is a simulink model. I have attached the Image.In the image one can see the red colored one marked which is the execution order. I would like to capture these order in a variable. I have tried the below command sldebug('modelname') slist

and it is displaying the order. But i want to read this order and store it in a variable where i can use this order for other evaluation purpose.
