State flow execution order

Hi,

I have a state chart whos purpose is to manage when to excecute some simulink functions. I am new to using stateflow, so maybe this answer to this question is self evident. Anyways, in one state the model is supposed to call two (simulink) functions, and their order of execution is important. I have used events to do this as follows:

Running

en:

stateFlag = 3;

du:

send(do_fcn1);

send(do_fcn2);

This model is suposed to run on a hardware platform in the end and my question is simply: Will the order in which I send out the events guarantee that fcn1 is called and completed before fcn2 when the code is compiled?

Regards, Robert

what event are you talking about?

[Robert]

Oh, maybe that was a bit unclear. The events (output to simulink) are 'do_fcn1' and 'do_fcn2'

Hi Robert,

yes it is: since your function calls do_fcnx trigger an atomic subsystem, the atomic subsystem will be simulated (entirely) one after the other.

Thanks Titus, that pretty much answers it :)

Hi Robert, your welcome. You might mark the question then as answered ;-).
