POP Assumptions:
- That the circuit is initialized close to steady state:
- Inductor currents are close to steady-state values
- Capacitor voltages are close to steady-state values
- Logic and Switches are in the correct states
- PWL sources are held at their t=0 values for the POP analysis!
- Large signal, non-repeating sources are also held at their t=0 values!
- That there is no low frequency perturbation to the circuit, e.g. soft-start.
