Can PLECS model non-linear passive components?

Problem description: 

In addition to ideal passive components, I'd like to model variable capacitance, inductance, and resistance, as well as the effects of saturation.


The PLECS library provides variable resistor, inductor, and capacitor components as well as variable resistors with series-connected inductors and parallel-connected capacitors. A piecewise linear resistor component is also provided and lookup tables can be further used to provide non-linear phenomena. In addition, saturable inductor and capacitor components are included.
