Hi, i have a pulse generator that i made frome delay as shown in picture, that is used to drive a motor through H-bridge, then i would to do some action based on the duration of one pulse, for example if i have apulse width =2msec, i would to perform an action if = 1msec another action, and etc.. with diffrent pulse width, the problem that i dont know how to get the puls width as double or boolean data to pe used with a stateflow or if function. can someone help me?? thanks.Screenshot 2019-12-19 at 17.07.32.png

Hi Mohamed,
Assuming you have the Frequency and Duty_Cycle as inputs to the model, you could calculate the Pulse Width as:
where PW = Pulse Width in sec, f = frequency in Hz , D = Duty Cycle in %.
using Product or Divide blocks in Simulink.
Hope it helps!
