    finding average,dynamic, static power Reply

     I have design the full adder with different style in virtuoso(cadence). I want to find the power consumption of the same. I have downloaded some manual  in which different methods are given to find the power. but I am getting different values for each method.


    I am using following method:

    virtuos Analog Design environment window select OUTPUT ..> saveall.

    In save all options enable all options.

    Run simulation.

    In waveform window select Browser..> results...> open results    , then Select Waveform Data base window will open ,here select psf file. In left side of waveform window we can observe a browser. In browser doble click on tran option 

    Here we can have current , voltage and power signals at various parts of the design.

    Double click on pwr option. Then we can observe wave of power signal in waveform window. 

    select pwr signal and do as follows to get avg power

    In Waveform window goto TOOL option open calculator.

    In calculator go for Functional panel select average function  and then clik on evaluate button.

    The obtained value is the average value.


     But If we measure the power using formula then I am getting different values.

     Please guide me on this topic.

    I am a student.
