why leakage power is changing by changing activity file? I think dynamic power had a direction relation with activity file ??

Hello,

I am synthesizing a 32-bit multi bit multiplexer (with cell instance of 100)and generating power reports by using .SAIF file that comes from simulation tool.

Initially I generating various .saif files by making various changes (no .of stimuls patterns) in the testbecnch file , But keeping the simulation time constant in all cases.

my question is, In various runs for various .saif files, my synthesis tool shows different dynamic power which is acceptable but why the leakage power is also changing ???

Regards,
Anil kumar k

Yes , it is sate dependent .
for better understanding you can open the lib file and see the power down function defined for each cell.

power_down_function : "!vdd+vss" something like this [and this depends of toggling info like vcd/activity]
