Power estimation at which level ? Transitor Level or Gate level.
With Gate-level you can go for PrimePower Tutorial.
With Transitor-level you can go for NanoSim and Hspice.
Both power estimation methodology and power categories are well defined there .
Hi,
for computing of leakage power in transistor level you can use hspice.
maybe .op instruction can help you because it computes the current and power in a special time with this operation.
But I mean system level power prediction.I want a paper that describes system level power estimation completely.
