I have designed a subcircuit by writing code and did a transient simulation. How would I know the power consumption or energy consumed by the circuit?

Hi san,
Please post your LTspice asc file, we can then help.

You can "instrument" the subcircuit to measure instantaneous voltage and current consumed, and by using the function evaluation and computation ability of the waveform viewer you can plot the instantaneous power consumption as well as compute the average power consumption, or the integral or the derivative of power consumption.

What code?

 

You can run a tran sim, hold down the Alt key and left-click on any component (e.g. the subcircuit power supply) to plot the power consumed by that component.
