please rca can you explain me how prime time px calculate leakage power and internal power using toggling rate and static probability !!! because the tool use also the value of .lib !! how we can write them like Switching power= 1/2 * Tr * C * Vdd^2 !!!!
and how it calculate peak power in time-based mode !!!!
The saif through the vcd from the simulation provides the value on the std-cell pins.
The SPEF provides the load on the pins.
The .lib provide the power table function of the load and the value on the pins.
This power table provides the leakage and the dynamic power.
So after that, it is quite easy to calculate the power and the peak-power which the strongest value at the time given by the saif.
yes
VCD value change dump: that's clarify!, The VCD capture the changed of all signals you want to log and the time.
By transition, in this case, we means the switch from 0 to 1 or 1 to 0, the slew time, this is provided by through the SPEF and the timing engine in primetime.
