How can we calculate number of power switches should be used in power gating technique for a design?
 

All I know about power switches is that any power switch should be able to handle the current neede by the load which it is controlling. Please if I am wrong correct me.
 

I found the answer for it....

Minimum no of power switches = ( Switch Resistance * Domain Current Consumption)/ Switch Voltage Drop
