2.15.5 Power Estimation
Since the total power consumption of the system heavily depends on many factors with regard to the
configuration/utilization of the Zynq Ult MPSoC device, it is highly recommended that the end user
perform some power estimation and analysis using the Xilinx Power Estimator (XPE). This tool is very
useful for plugging in various parameters and getting an estimated power consumption estimate for the
system.
When designing the UltraZed-EG SOM architecture, the XPE tool was used to ensure that the UltraZed-EG
SOM system could supply enough power to the Zynq Ult and its on-board peripherals using worst
case parameters including logic utilization, operating frequency and temperature while still supporting low
power modes and various speed grade options.
Since the power supply for the VCCIO rails for banks 26, 64, 65 and 66 are supplied from the end-user
carrier card, it is important to make sure that the end-user carrier card power supplies are adequate to power
these rails over the desired and/or estimated operating scenario.
NOTE: When designing a custom UltraZed-EG carrier board, be sure to use XPE (Xilinx Power
Estimator) to estimate the power needed by the Zynq Ult MPSoC device. The designer will
need this figure in sizing the input supply to the UltraZed-EG SOM.
NOTE: In addition to the XPE results for the Zynq Ult MPSoC, the end user will need to add
to their power estimate to compensate for the power that is needed for the on-board devices that
exist on the UltraZed-EG SOM such as the various memory, USB and Ethernet PHY devices, and
serial devices.
2.15.6 System Monitor (SYSMON)
The Zynq Ult Architecture supports an on-chip system monitor. SYSMON monitors the physical
environment via on-chip temperature and supply sensors with integrated analog-to-digital converters (ADC).
An overview of the System Monitor primitive, SYSMON, is provided by Xilinx User Guide
UG580 -
UltraScale Architecture System Monitor.
The UltraZed-EG SOM supports System Monitor functionality thru the JX connectors to a SYSMON header
that would be implemented on the end-user carrier card. The UltraZed-EG SOM contains selectable
reference voltages via a 0-ohm resistor jumper. The following figure depicts the implementation of the
system monitor on the UltraZed-EG SOM.
