Power Calculations
1. Number Of The Core Power Pad Required For Each Side Of Chip=(Total Core Power)/{(Number Of Side)*(Core Voltage)*Maximum Allowable Current For A I/O Pad)}
2. Core Current(mA)=(CORE Power)/(Core Voltage )
3. Core P/G Ring Width=(Total Core Current)/{(N0.Of.Sides)*(Maximum Current Density Of The Metal Layer Used For Pg Ring)}
4. Total Current =Total Power Consumption Of Chip(P)/Voltage(V)
5. No.Of Power Pads(Npads) = Itotal/Ip
6. No.Of Power Pins=Itotal/Ip
Where,
Itotal =TOTAL Current
Ip Obtained From Io Library Specification.
7. Total Power=Static Power+Dynamic Power
=Leakage Power+[Internal Power+Ext Switching Power]
=Leakage Power+[{Shortckt+Int Power}]+Ext Switching Power]
=Leakage Power+[{(Vdd*Isc)+(C*V*V*F)+(1/2*C*V*V*F)]
