How can i simulate pwm signals with c2000 series.

i can't use scope with pwm block and i want to see only simulated signals in scope like proteus simulation.Not real.Please help me.

Hi,

We can log the input signals like GPIO input, ADC readings. We can also log state of variables using memorycopy block. So in case of GPIO output, you can identify the variable whose value would eventually be written GPIO output register and log the state of the variable, which would give an effect of logging the output signal itself.

The same approach may not be possible with PWM as it a combination of values that would eventually generate the output. Since much of this activity of using multiple data sets to generate the PWM signal is done by hardware, it is hard to trace the signal activity.

So, with ePWM block or any other block it is not possible to log the PWM signal in simulink environment.
