I am developing a application with STM32F746G discovery board with my sensor, and I reference AN4749 to design a lop-power control flow.
But I don't know how to measure/monitor/analyzing the power consumption to make sure whether my design is work or not.
Is there any software tool that can do this? Or I need to buy another hardware tool?
Thanks for any kind support.

Remove JP1 and use a current monitor in its place.

For now, my power supply is from USB(CN14).
Are you mean that I need to remove the jumper (5vlnkusb <-> 5v) and put my current monitor between those 2 pins?

Got it, thanks. I will check it later.

And if you really want to know what's going on in your low-power battery-operated system, buy a Joulescope! Best product for everyday embedded engineers in the past decade, IMO! I just keep mine attached to the board I'm working on and run it continuously.
