1 POWER ANALYSIS Sai Siddharth Kumar Dantu ELEC7770 Advanced VLSI Design Team Project Advisor: Dr. V Agrawal

2 Objective To perform the power analysis of a 32 bit processor.

3 Power components in CMOS circuit V DD Ground CLCL R on R=large v i (t) v o (t) Dynamic power Short circuit power Leakage power Power =CV DD 2

4 Components of Power Dynamic –Signal transitions Logic activity GlitchesShort-circuitStatic –Leakage P total =P dyn + P stat P tran + P sc + P stat

5 What I have done so far Used Jins’s tool to evaluate the power of the ALU block of the processor.

6 Clock period applied is 20ns Random vectors applied are 1000

7 Results Minimum leakage power observed : 33438pW Maximum leakage power observed : 37304pW Minimum dynamic power observed : 73.67μW Maximum dynamic power observed : 275.33μW

8 Average dynamic power 154.7 μW Avg short circuit power 32.94 μW Average leakage power 3526.13 pW Total average power 187.69 μW Maximum total power 338.63 μW

9 Results Percentage of dynamic power present in the total average power is 82.42% Percentage of leakage power is 0.01878% Percentage of short circuit power is 17.55%.

10 Work still to be done The power analysis of the entire processor has to be done.
