Does the square pad on the back side of the QFN package need to be connected to ground?

I'm playing with you design kit and want to ensure I get the design right. . .

Thanks

Usually the EPAD of an IC will be connected to GROUND of the PCB board. You could also check the Cadance PCB file if you have installed EZ-Serial SDK.
