    Hi,
    My query is..
    The circuit equivalent of the interconnect consists of:
    1) initially a driver ( a pmos-nmos pair)
    2) R,L,C
    3) a repeater ( again a pmos-nmos pair)
    4)R,L,C
    ------------------------------- and so on and finally a capacitive
    load

    This schematic is extracted in to t-spice and i am suppose to find out
    the power dissipation in the circuit.

    I want the exact command to find the total power dissipation which
    includes short circuit power,leakage power,dynamic power

    or at least to calculate the average power of the entire circuit.

    Please anyone give me the response with answers,..
    Thanks

    Hi Sreeniv,

    I don't know this simulator and have no idea about how it could handle
    your query.
    What you could do is to sense the current drained into the ground
    using a 0-V voltage source for instance. You could then calculate the
    power knowing the operating voltage. You could do this in either DC/
    Tran.

    Hope this helps,
    Riad.
