to calculate power

[vicky]

hi,
To calculate power in cadence ic 5.1 when i make a symbol of the
schematic and select the Vdd terminal on the symbol to figure out
the current, it select the Vdd pin of the schematic. As i have so
many Source of pmos to select what should i do.

You create a "small" resistor between the voltage source and the VDD! net
and then plot the current through this?

i even tried that but i am not sure as that is the correct value
because it gives me a current that is too small something lin pico.
so i am not sure whether it shows a correct value bcoz when i tried
to see it for a series of 3 inverter i get the current in micro Amp.
so wht do u suggest me to do.
