how to reduce power dissipation in deep submicron....

archive

Hi all,

please can anybody give me information about power analysis in the deep submicron technology.

  • If you look inside the .lib file and search for the word "power", you will find parameters for leakage and dynamic power.

    For leakage power, it could be a constant value or a state dependent value. If it is state dependent, then you need to figure out the percentage of time a cell is in each state and ratio the leakage power accordingly.

    For dynamic power, there are lookup tables that determine the power parameters. You provide the toggle frequency and capacitance loading, and RC calculates the power for you. I don't know the algorithm or formula for this calculation.but it is very tedious. You probably don't want to do this by hand.
