Build ramp in Simulink for DSP implementation

I am using a counter limited block to make the angle signal for PWM generation. I use fixed point 32 bit signals, When I run the simulation in simulink the signal frequency is 60 Hz but when I run the DSP the signal output is 50 Hz. Do you know what I am missing here?

Hi Marzieh,

What is the number of bits by which you shift the signal coming into the Shift Arithmetic block?

Thanks!
