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.

Solution: 

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.
