Hi support team,

I tried to realize epwm phase shift with CLB but has no success.

I created a pwm signal form EPWM1. I want to use CLB let it delay some ns.

Could you provide any example or a block to let me know how to do that?

So you want to send in your EPWM1A into the CLB, then take out of the CLB, a DELAYED version of EPWM1A?

Okay, we dont have an example for this but i'm sure this is doable. So the logic you would really need is detecting the rising and falling edges in the input filter, then having a counter to output the edge to the FSM after the delay (phase shift) has been elapsed.
