Power Measurement in ZCU102

Jump to solution

Is there a way to physcially measure the power of the Zynq Ultrascale+ part in the ZCU102 board? I dont see too many resistors that could be used to take the measurement as was suggested in one of the forums.

Any help would be greatly appreciated!

Hi @leena.jacob ,

Power Comsumption all depends on the Design you are loading into the FPGA.

Xilinx recommends to follow below methods to calculate power: 

Using Xilinx Power estimator(UG440) and VIVADO power analyzer(UG907) are one of the most common practices in power estimation which also gives details about the resource utilization.

The accuracy of XPE is dependent on two primary sets of inputs:

• Device utilization, component configuration, clock, enable, and toggle rates, and other information you enter into the tool

• Device data models integrated into the tool

You can also use SCUI (Download related files)which will give Power consumption at particular time (One you hit Power button, it will give power consumption at that instant).

You can also get live Voltage and current values for all rails by using Maxim tool. You need Maxim Dongle for this, you can get it for free by following this AR#62629.

 

Hope this helps.

So other than using the Maxim Dongle, there is no measuring point that could be used on the board to physically measure power consumption of the Ultrascale+?

The schematic shows current sensing resistors on all of the switching supplies.  I think most or all ofthem are on the bottom of the board.

Hi leena,

You can also use ZCU102's System Controller. Check pages 26 & 27 of XTP433:

Thanks,
Andres
