Power Consumption

The maximum power consumption of a module mainly depends on the design which is running on the FPGA.

...

There are following dependencies how the initial voltages of the power rails on the B2B connectors are distributed to the on-board DCDC converters, which power up further DCDC converters and the particular on-board voltages:

...

Following diagram clarifies the sequence of enabling the three power instances utilizing the DCDC converter control signals ('Enable', 'Power-Good'), which will power-up in descending order as listed in the blocks of the diagram.
