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.
