Matlab stateflow execution time

Hi all,

I am using a pulse generator as an event to switch from one state to another. The pulse is set as follows:

Amplitude=1; Period(sec)=2; Pulse WAIDTH= 50%; pHASE DELAY=0;

Why is the system still being executed in milliseconds that I can barely see it ?

(NOTE: Simulation stop time is set to infinity)

Is there a time that I need to set so that the state changes every 2sec as specified in the pulse generator?

Thanks in advance.
