VCCA_PLLn

I know the Stratix II device handbook says I must connect the VCCA_PLLn even if I'm not using PLLn. But do I really have to? What will happen if I don't? I want to save all the power I can.

If I don't need a PLL I generally just connect the suppy unfiltered to VCCint. In other words I don't bother with any filtering since I won't need it. Do any of you think this is a problem?
