    CCA
    . The rest of the formula provides a
    very small number that can be considered negligible.

    Step #5:
    Compare Estimated Power Consumption against
    Characterized Power Consumption
    The estimated total power consumption for this design is
    1.46W. The characterized power consumption for this design
    at 200 MHz is 1.0164W.

    shows the characterized
    power dissipation numbers for the shift register design
    using frequencies ranging from 1 MHz to 200 MHz.
