How does PTPX calculate switching power.

When I do

get_attribute [get_cells $cellname] switching_power

I get a value. How does the tool arrives at this value. report_power_calculation gives the leakage and internal calc but not switching. I am well aware of the formula 1/2 CV2 FA

I quueryed C using get_attribute ba_capacitance_max on the output net of the cell and the switching activity (FA) using the get_switching_activity on the output pin but I can't arrive at the value I get use the get_attribute [get_cells $cellname] switching_power command. What gives. Am I querying the wrong attributes?
 

Switching power is available on the net objects.
You are querying switching_power on cell which is unavailable.
