Hi @Durba Chatterjee,
The Cora Z7 does not have a way to measure current usage internally like the ZC702 or the Zybo Z7 boards. There is a PMIC on the board, but looking through it's datasheet, https://www.dialog-semiconductor.com/products/soc-processor-pmics/da9062#tab-field_tab_content_resources, I don't believe you would be able to directly get the current usage from that IC anyways.
Xilinx does have a Power Estimator tool, https://www.xilinx.com/products/technology/power/xpe.html, that can give you some good details on power usage, but Digilent does not have any guides on using this tool.
Thanks,
JColvin
