Monitoring Voltage and Current
[Figure 2-1, callout 32]
Voltage and current monitoring and control are available for the Maxim power system
controllers via the Maxim PowerTool software graphical user interface. The onboard Maxim
PMBus MAX15301, MAX15303, and MAX20751 power controllers listed in Table 3-27 are
accessed through the 2x8 keyed shrouded PMBus connector J84, which is provided for use
with the Maxim PowerTool USB cable (Maxim part number MAXPOWERTOOL001#). This
cable can be ordered from the Maxim Integrated website [Ref 34]. The associated Maxim
PowerTool GUI can be downloaded from the Maxim website. This is the simplest and most
convenient way to monitor the voltage and current values for the power rails listed in
Table 3-27.

[Figure 2-1, callout 35]
UltraScale FPGAs provide an analog front-end (SYSMON) block. The SYSMON contains a
single 10-bit 0.2 MSPS ADC. Consequently, the sequencer for SYSMON does not support
simultaneous sampling mode or independent ADC mode. See the UltraScale Architecture
System Monitor User Guide (UG580) [Ref 20] for details on the capabilities of the analog
front end. Figure 3-30 shows the KCU116 board SYSMON support features.
