The total device power must remain under 50W. To assist the Vivado tools in reporting when
power exceeds this amount, add this XDC constraint:

Monitoring Voltage and Current
Voltage and current monitoring and control are available for the Infineon power system
controllers through the Infineon PowIRCenter graphical user interface. The PMBus interface
controllers and regulators are accessed through 1x3 PMBus connector J21, that is provided for
use with the Infineon PowIRCenter USB cable (Infineon part number USB005) and can be
ordered from the
website. The associated Infineon PowerTool GUI
can be downloaded from the Infineon website. This is the simplest and most convenient way to
monitor the voltage and current values for the Infineon PMBus programmed power rails listed in
.
Each Infineon PMIC controller is capable of reporting the voltage and current of its controlled rail
to the Infineon GUI for display to the user. Fourteen rails have a TI INA226 PMBus power
monitor circuit with connections to the rail series current sense resistor. This arrangement
permits the INA226 to report the sensed parameters separately on the INA226_PMBUS. The
rails configured with the INA226 power monitors are shown in
