Hi,

To measure the current drained by an FPGA board, Kindly place a series (shunt) resistor on the power supply line (active load). Now, the current will be the voltage across the shunt resistor divided by the resistance value itself. Note, it must be a very low resistance with high accuracy ( with the value averagely low) so that it does not affect the real current drained. You may put it on the main power supply line, but in that case, you will measure the total current drained by the board. Once you determine the current that only the FPGA uses, you can put a shunt resistor on the FPGA core supply line (Please check the voltage regulator on the board), check a suitable point to interrupt the supply path and insert the resistance. You can then measure the power drain/consumption.

Arnab,

power consumption of fpga circuits is measured as indicated by Kennedy. If you want to estimate the power consumption during the design process you can use the power estimator software within the design CAD tools. For more information please follow the link:https://www.altera.com/content/dam/altera-www/global/en_US/pdfs/literature/ug/ug_pc.pdf

There may be a similar tool for Xilinix FPGAs.

Best wishes

also we can estimated Power consumption for the transmitter and receiver after simulation result which store in a SAIF file , then performance of the power analysis is obtained for power estimation using Vivado;s power analyze . this tool very good for transceiver design and it is easy to used it

thanks

U can use Xpower analyzer from Xilinx , this analyzer takes certain input files viz .ncd file, pcf files

Sabir Hussain sir by using Xpower analyzer from Xilinx is acceptable one or not
