Capability of Xpower



I want to know about the capability of Xpower. I have read in research literature on more than 3 places, that Xpower can be used to generate a text file that contains power consumptio versus time.


I have VCD file generated by ModelSim and ncd file generated by Xilinx, but i am unable to do so.


I want to know whether its possible or not? if yes then how?



Best Regards,

Re: Capability of Xpower



XPower Analyzer (also referred to as “XPA”) is an interactive graphical tool used to perform the following functions on your design:
  • Analyze power consumption for Xilinx® FPGA and CPLD devices.
  • Report thermal information (junction temperature).
  • Report static and dynamic power for the different voltage supplies.
  • Validate the accuracy of the estimation given in the Xilinx Power Estimator spreadsheet.
  • Analyze power data supplied by hierarchical power reporting.
  • Examine the data for areas where power can be reduced.
  • Generate design power consumption reports and add them to the overall project documentation
  • Reads VCD simulation data from the ModelSim family of HDL simulators to set estimation stimulus, reducing setup time, as well as from the additional simulators listed in Simulator Support.
Note Power estimation for a Zynq™-7000 AP SoC design implemented in ISE will not appear automatically in XPower Analyzer. For a method to import Zynq-7000 power estimation into XPower Analyzer, see Answer Record 51902 on the Xilinx website.
