Hi Julia,
You can implement frequency-dependent resistors and inductors in Hspice
using frequency-dependent controlled current or voltage sources, the
LAPLACE function in G or E elements. It lets you specify the frequency
dependence in a pole-zero form or as a frequency table. The pole-zero
form is simulated faster and more accurately.
There is also magnetic core model for L elements (inductors). That one
accounts not only for the frequency dependence but also for the
nonlinear hysteresis effects in ferromagnetics.
