A switch using the XSPICE analog switch model.

TODO: Somehow model contact bounce.

Instance Variable	N	The number of ganged switches. There will be twice as many nodes as switches, with each successive node pair corresponding to one switch in the gang.
Instance Variable	t0	The time at which the switch transition is completed.
Instance Variable	t1	The time at which the switch reverts to its original state (`None` if it never does)
Instance Variable	tr	The transition (control rise) time of the switch transition.
Instance Variable	td	Delay between transition of first switch and transitions of all others in the gang. (Obviously ignored if N=1.)
Method	nodes	Property: a0, a1, b0, b1, ...
Method	setup	Subcircuit definition.

Inherited from SwitchMixin:

Instance Variable	R_off	Resistance in OFF state. Typically very high.
Instance Variable	R_on	Resistance in ON state. Typically very low, but can't be any lower than 1 mOhm (1E-3 Ohms).
Instance Variable	log	Set `True` to use log transition between resistance states instead of linear.
Instance Variable	initially_on	Set `True` if the switch goes from R_off resistance to R_on. Otherwise, it starts out with R_on resistance.
Method	asModel	Returns an XSPICE analog switch model with the supplied prefix.
Method	st_vctl	Undocumented
Class Method	_nodes	Undocumented

N =

The number of ganged switches. There will be twice as many nodes as switches, with each successive node pair corresponding to one switch in the gang.

t0 =

The time at which the switch transition is completed.

t1 =

The time at which the switch reverts to its original state (None if it never does)

tr =

The transition (control rise) time of the switch transition.

td =

Delay between transition of first switch and transitions of all others in the gang. (Obviously ignored if N=1.)

def setup(self, f):

overrides pingspice.circuit.netlist.Subcircuit.setup

Subcircuit definition.

Why use f? Because it's short and a conveniently typed letter on the keyboard.

Override this if your subclass does not reference a param.ParameterFinder subclass via the Finder class attribute. As with Include.setup, your override method can return a dict of attribute names and values to set in my instance.
