        Welcome in the fascinating world of PSoCs!   
Since the voltages are applied to the PSoC the configuration are your power-lines. To tell the PSoC what you applied go to the .cydwr-file and choose the "System" tab. There you specify VDD Digital, VDD Analog (which may not be higher than VDDD). Additionally you may specify different voltages for the 4 quadrants of the PSoC I/O pins (Not higher than VDDD, too).

        Sorry, an Error in my post before.   
Excerpt from the Family Datasheet:   
VDDA. Supply for all analog peripherals and analog core regulator. VDDA must be the highest voltage present on the device. All other supply pins must be less than or equal to VDDA. VDDD. Supply for all digital peripherals and digital core regulator. VDDD must be less than or equal to VDDA.

Why the Vdda should be higher than Vddd?

Have a look into the PSoC5 Family TRM. (Chinese version here)

   

Excerpt: "VDDA. Supply for all analog peripherals and analog core regulator.
VDDA must be the highest voltage present on the device. All other supply pins must be less than or equal to VDDA."
