The following power consumption numbers were obtained using Virtex-4 WebPower Tool Version 3.0.
SPI-4.2 v7.1 Core and Lite v2.0.1 Core were used for the estimation; however, they can be used for the updated versions of the cores for estimation. These numbers are conservative estimates. For this estimation, device XC4VLX25-FF668 was used.
Power estimation for Virtex-5 will be available at later date. Please contact Xilinx Technical Support for the schedule.
