Can someone help me figure out where does power analysis of Cadence Encounter RTL Compiler comes from

Haoxiang

Hi all,

 New to this area, I have two questions that need your help. 

1st, when I get the power analysis from Cadence Encounter RTL Compiler, It automatically shows Leakage, Internal, Net and Switching Power of the generated schematic. But then I get comfused, under which input pattern does the Compiler infer all the power values, especially switching power, since it's directly related to the frequency of input?

 2nd, what's the difference between Leakage Power and Internal Power? And does Net Power means power consumed from the interconnect? I get confusion about these terms

 Thank you very much for your notice and help!

Best

     Hi Haoxiang,

    1.leakge of dynamic power is not only short circuit power but it is also calculating ir drop during Charging and discharging of load capacitances.

    so  dynamic power leakage= short circuit power+ power dissipation during Charging and discharging of load capacitances.

    2.Yes net power related to static IR drop.its independent of switching activity means dynamic power.
