Chapter 1:
VCU110 Evaluation Board Features
The VADJ_1V8_FPGA rail is programmed to 1.80V by default. This rail powers both the FMC
HPC0 (J22) and FMC HPC1 (J2) V
ADJ
pins as well as the XCVU190 HR banks 84 and 94 (refer

Documentation describing PMBUS programming for the Maxim InTune power controllers is
available at the Maxim website
The PCB layout and power system design meets the recommended criteria described in the
UltraScale Architecture PCB Design and Pin Planning User Guide
(UG583)
.
Monitoring Voltage and Current
Voltage and current monitoring and control are available for the Maxim power system
controllers through the Maxim PowerTool graphical user interface. The onboard Maxim
InTune power controllers listed in
are accessed through the 2x8 keyed shrouded
PMBus connector J39, which is provided for use with the Maxim PowerTool USB cable
(Maxim part number MAXPOWERTOOL001#), which can be ordered from the Maxim
website
. The associated Maxim PowerTool GUI is also downloadable from this
Maxim site. This is the simplest and most convenient way to monitor the voltage and
current values for the power rails listed in
SYSMON Power System Measurement
UltraScale FPGAs provide an analog front end (SYSMON) block. The SYSMON contains a
single 10-bit 0.2 MSPS ADC. The VCU110 board SYSMON ADC interface includes current
measuring capability for all Maxim power controller sourced rails. The Maxim PowerTool
GUI can display the rail voltage for all Maxim power controller sourced rails.

rail voltages can be displayed through the SYSMON internal
voltage measurement capability.
The MGTAVCC and MGTAVTT rail voltages can be displayed through SYSMON channels AD0
and AD8, respectively.
