ind_sw :
A switchable inductor circuit element.

The ind_sw primitive represents a two-terminal inductor of which inductance can be controlled by a third input L. In other words, the inductance between the two terminals pos and neg switches to a new value indicated by the real-typed input L whenever its value changes. The total flux stored on the inductor is preserved before and after each switching event.

Since every value-change event of the input L triggers a new computation, the ind_sw primitive is not recommended for modeling inductance that continuously varies with a voltage or current (use a ind_var primitive for nonlinear, current-dependent inductance). The ind_sw primitive is intended mainly for inductance that switches between discrete levels (e.g. inductance programmable via digital control).

Note that this primitive is a pseudo-module to describe a structural netlist of electrical circuits and not a behavioral model by itself. The XMODEL simulator extracts an event-driven behavioral model at run-time based on the circuit network described by these circuit-level pseudo-modules.
