ZCU106 Board User Guide 126UG1244 (v1.0) March 28, 2018 www.xilinx.comChapter 3: Board Component DescriptionsMonitoring Voltage and CurrentVoltage and current monitoring and control are available for the Maxim power systemcontrollers through the Maxim PowerTool graphical user interface. The on-board MaximInTune power controllers listed in Table 3-54 are accessed through the 2x8 keyed shroudedPMBus connector J84, which is provided for use with the Maxim PowerTool USB cable(Maxim part number MAXPOWERTOOL001#). This cable can be ordered from the Maximwebsite [Ref 22]. The associated Maxim PowerTool GUI can be downloaded from the Maximwebsite. This is the simplest and most convenient way to monitor the voltage and currentvalues for the Maxim PMBus programmed power rails listed in Table 3-54.Each PMBus programmable Maxim controller can report the voltage and current of itscontrolled rail to the Maxim GUI. A subset of the programmable rails and two fixed railshave a TI INA226 PMBus power monitor circuit with connections to the rail series currentsense resistor. This arrangement permits the INA226 to report the sensed parametersseparately on the PMBus. The rails configured with the INA226 power monitors are shownin Table 3-54.As described in I2C0 (MIO 14-15), page 60, the I2C0 bus provides access to the PMBuspower controllers and the PS-side and PL-side INA226 power monitors via the U60PCA9544A bus switch. All PMBus controlled Maxim regulators are tied to theMAXIM_PMBUS, while the INA226 power monitors are separated to PS_PMBUS andPL_PMBUS.Figure 3-17, page 61 and Table 3-21, page 63 document the I2C0 bus access path to theMaxim PMBus controllers and INA226 power monitor op amps. Also, see schematic0381770. The MPSoC core related power rail measurements (PL_PMBUS) and PS relatedpower measurements (PS_PMBUS) are accessible to the system controller and MPSoC PLlogic through their respective I2C0 bus connections.These measurements are displayed in the system controller menu selections. The Maximcontroller PMBus is accessible by the system controller, which can also display the railvoltage measurement made by its sourcing Maxim controller. User IP in the MPSoC PL canaccess the same set of PMBus resident devices through the logic I2C0 connections.Send Feedback
