question about basics of power measurement...

In the power equation, we have

1) static power by = I X Vdd

[static]

2) switching power = 0.5 X C X (Vdd^2) X f

[dynamic]

3) short circuit power = Q X vdd X f X N

[dynamic]

4) leakage power = I(leak) X Vdd

[static]

How do we measure these components?

-For finding static power, we find total current flowing (from voltage

drop across register). and Multiply it by Supply voltage (core

voltage). right?

-How do we measure switching power of processor assuming maximum

switching activity? we know f and Vdd. What about C ?

-How do we measure short circuit power ?

-Can we disable clock to find leakage power component of static power?

Thanks,

Nilesh
