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

= 1.4628W
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.
Figure10
shows the characterized
power dissipation numbers for the shift register design
using frequencies ranging from 1 MHz to 200 MHz.
