OK to leave Cyclone IV E PLL Power pins grounded or connected to VCCINT?

I am building a Cyclone IV E design that doesn't use the PLLs. Do I still need to provide a 2.5V power rail for the PLL power pins? Or can I just connect them to ground or VCCINT (1.2V)?

From the Cyclone IV documentation (AN 592: Cyclone IV Design Guidelines):

"Connect all PLL power pins to reduce noise even if the design does not use all the PLLs—VCCA to 2.5 V

and VCCD_PLL to 1.2 V or 1.0 V"

This doesn't directly address the case where the design doesn't use ANY PLLs.

It would sure make things easier if I had one less voltage regulator to worry about!
