How to synchronize various ePWM modules in f28335 using simulink

Hi all,

I am using f28335 and simulink to generate pulses. I am using ccs 6.0. I want a SPWM signal and two complimentary square PWM signals as shown in image.

</matlabcentral/answers/uploaded_files/30863/a.jpg> I am attaching the simulink model which I am using. I tried several options, but unable to synchronize. Please tell me what modifications I have to do, so that I can get all Pwm pulses to synchronized.

Thank you.
