The simulator supports the specification of voltage and current initial conditions on capacitor and inductor models, respectively. These models are not the standard ones supplied with SPICE3, but are in fact code models which can be substituted for the SPICE models when realistic initial conditions are required.

* This circuit contains a capacitor and an inductor with
* initial conditions on then.   Each of the components
* has a parallel resistor so that an exponential decay
* of the initial condition occurs with a time constant of
