Xpower Static Current

[raj]

Hi,
I have a quick qustion regarding Xpower.

Does it report the static(leakage) power/current consumed by the
current design.
The Quiescent Current Definition says "Current Flow into the
Device with no signal switching".But I am not sure whether Quiescent
Current includes the Static Current.Even if in the design I add/delete new
components the Quiescent current remain same.Please advise.

regards

If you think about the nature of static current you will realize that
"adding" components to your design will have no effect on it.
Regardless if your design uses the components on the chip, the logic is
still there and will draw static power. When you use a component, you
then need to include it in your dynamic power calculations since it will
be switching.

The chip will draw the same static power even if your design has no
components.
