I am absolutely sure we are measuring static power.
I just got confirmation from a personal contact at a large defense contractor that they are seeing the same problems.
They said in an email to me:
Power consumption is a BIG issue.
Altera has been prescreening parts in order to meet the power specifications as they were specified initially.
Supposedly Altera is having problems with yield/process variation.
The 2.5 VCCaux that powers the configuration memory seems to be a major culprit.
This voltage rail is drawing substantially more current than advertized originally.
Altera is definitely aware of the issue, you have to alert them that you are having problems.
