Hello all,

I have a netlist of a circuit, How do I measure the consumed by that circuit in OrCAD Pspice A/D?
Please hep me.

Thanks
 

Hi,


You can measure the Integral of the current drawn from the source and then multiply it by your supply voltage. Be careful on the timestep of your simulation, it affects the results.


Cheers
 

If you have just single supply, you can follow the method suggested by dnanar.
There is more straightforward method, is by putting a power probe (or plot W trace) in pspice. The power plotted is the instantanious power. You would need to take average of this to get averaged power. Also measure this for time range when the circuit is in steady state for a number of cycles (if it is switching ckt).

If you are using behavioral devices in your circuit, then power plotted would be of no significance, as it would not truly represent real-life scenario.
 


Hi thanks for the help,
Should I plot the W trace for the output terminal?
 

If you are looking for power dissipated in ckt, then calculate power supplied by source and subtract power delivered to load. This would give power dissipated in intremediate ckt.

If you are looking for power delivered to load only , then plot W trace for output load.
