 For this method, we will need to be in architectural abstraction level.<br /><br />
 The system is then divided into functional blocks (CPU, Memory hierarchy, interconnection bus,peripherals,...) and we can have an application consumption E<sub>app</sub> by adding the individual consumption of each block E<sub>bl</sub>.<br /><math>E_{app}=\sum E_{bl}</math><br />

 When we talk about the second criterion, the models are generally based on datasheet information and need a full knowledge of the underlying level architecture (low-level hardware through VHDL and Verilog descriptions).<br /> <br />

 For these measurements, we can build our models following several methods. The two mentioned are either electrical stimulation or inter/extrapolation from measures on a prototype.<br /> <br />

 The second section of the paper is about the state of the art of the non-intrusive measurement.<br />
 This part deals with different methods used to characterize VLSI (Very Large Scale Integration) circuits. These VLSI circuits can be organized using two criteria : the level of hardware abstraction of the circuit and the calibration method.<br /> <br />
