Zynq Ultrascale+ Power Sequencing

Jump to solution
1. In Zynq Ultrascale+ (XCZU9-2FFVB1156I), the power consolidation option given in "ug583, page no 34, table 1-13", what should be the order of power sequencing. Is this table means that power regulator "1" should be start first , then 2, then 3 and so on? 2. What is the mean by "user defined" in this table? Is it means that these regulators can be "powered on" in any order? 3. If any power sequencing order is not followed as recommended then whether it will create any boot-up problem or misbehave in performance? Thank you

Hi @alokbel 

Yes, the recommended power sequence for more info, please see page 15~page 16:

User-defined means those power can be unconnected or Grounded according to recommendation if not used.

Thanks
Simon
