Are there any known issues with the VCCPD voltage power reported by the Quartus II software PowerPlay Power Analyzer for Stratix III devices?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The Quartus® II PowerPlay Power Analyzer versions 7.2 SP1 and earlier may not correctly report the VCCPD voltage for Stratix® III devices.

If the VCCIO of an I/O bank is set to 3.0 V, the VCCPD requirement is 3.0 V, and if the VCCIO of an I/O bank is set to 3.3 V, the VCCPD requirement is 3.3 V. However the PowerPlay Power Analyzer incorrectly reports the VCCPD voltage as 2.5 V.

This problem is fixed beginning with the Quartus II software version 7.2 SP2.
