2.10.4  PCB Bypass / Decoupling Strategy 

The PicoZed 7010/7020 design follows the PCB decoupling strategy as outlined in UG933 for the 
7Z020, CLG400 package. The PicoZed 7010 depopulates a few of these capacitors while 
maintaining the listed requirements.

2.10.5  Power Good LED 

A green status LED, D1, illuminates with the U18 3.3V power rail. Since this regulator is the last 
one in the sequence to come up, it is an effective indication that all regulators are on. 

2.10.6  Power Estimation 

Since the total power consumption of the system heavily depends on many factors with regard to 
the configuration/utilization of the Zynq 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. 
 
The XPE tool can be downloaded from the following link: 
 

http://www.xilinx.com/products/design_tools/logic_design/xpe.htm

 

 
When designing the PicoZed 7010/7020 power system, this tool was used to ensure that the 
SOM system could supply enough power to the Zynq and its on-board peripherals using worst 
case parameters including logic utilization, operating frequency and temperature.  
 
Since the power supply for the VCCIO rails for banks 34, 35, and 13 are supplied from the 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 PicoZed Carrier Board, be sure to use XPE (Xilinx Power 
Estimator) to estimate the power needed by the FPGA.  The designer will need this figure in 
sizing the input supply to the SOM.  In addition to the XPE results for the core power supplies, 
Vccint/Vccpint (1V) and Vccaux/Vccpaux/Vccpll (1.8V), you will need to add an additional 2.4W to 
your power estimate to compensate for the additional power that is needed for the peripherals on 
the PicoZed System-On-Modules such as memory and USB and Ethernet PHY devices. 

2.10.7  XADC Power Configuration 

 
The XADC component is powered from the filtered 1.8V VCCaux supply utilizing the on-chip 
reference as shown below.
