Hello,
I have a 2 questions.
Although HRPWM can be adjusted at 150 ps, I think that jitter and noise exist in the actual waveform.
1. What is the resolution of HRPWM in consideration of jitter and noise in each cycle?
2. What is the minimum time of HRPWM's dead band when considering jitter and noise?
Regards,

So HRPWM works using "delay" elements. Meaning the HRPWM delay is not connected to a clock. There are actual delay elements which will delay the signal and you can enable a different number of elements to delay the edges of the PWM signals. Now with that said, your delay elements will change slightly with temperature and device voltage. You can always run the SFO function periodically to measure the MEP_scalefactor and use that in your HRPWM calculations.
But overall you should try some of our C2000Ware examoples and tryout the HRPWM for yourself. It gives you very nice stable high resolution PWM signals.
You can also take a look at some thread that talk about similar things:
