Sir, I am trying to take my sine wave as pwm output from the dsp kit(F2812). How to use the compare pwm block to adjust the pwm frequency for different range of sine wave.

You don't need to change the PWM frequency, only the sin frequency. The attached diagram will do a 60 Hz sin. Right click the ramp and change frequency to get different sin frequencies.
