How do I estimate the power requirements for the PLL analog voltage supply?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The Early Power Estimator (EPE) for Stratix® II, Stratix II GX, Cyclone®  II, and Arria™ GX devices provides estimations for the total power consumed by each PLL.  This power estimate is a combined total between the digital voltage supply (VCCD) and the analog voltage supply (VCCA). 

When designing the VCCA supply, you can use the total power estimate provided by the EPE for the PLL as a guide.  Although this estimate includes the VCCD requirements, this approach will provide some margin in your VCCA power supply design.
