1) Please make sure that the power domain decoupling caps follow the recommendations in An70707 application note.

Thanks again for all your answers.
But going back to question 1. I was not too concerned about my caps as I will follow the AN70707 note. But the datasheet states the a specification called Vramp. "Voltage ramp rate on core and I/O supplies" in the notes section "Voltage ramp must be monotonic." So what do you exactly mean by that? Both the 3.3V and 1.2V for the core voltage and in my case the VIO need to ramp up smoothly? Do they both have to rise at the same rate? Or something else?
Thank you again.
There is no requirement on the power up sequence for the FX3 device
