File source providing piecewise-linear source voltage values vs. time.

Make your source waveform as complicated as you wish!

Instance Variable	t	A Numpy vector of increasing simulation time points.
Instance Variable	X	A Numpy vector with the same length as t of source voltages.
Instance Variable	filePath	The full path of a file to be (over)written with t and X data. Any home directory symbol ("~") will be expanded. If `None` (the default), a new, unique temporary file path will be used.
Instance Variable	keep	Set `True` to keep the file after Python shuts down. The default is to automatically delete it, but you may want to keep it for study.
Instance Variable	gain	A scalar for amplifying the signal (default is 1.0).
Method	writeData	Opens a new tempfile for writing and for Ngspice to read during this Python session. (Gets deleted when Python shuts down.)
Method	setup	Subcircuit definition.

Inherited from NodeStuff (via Subcircuit):

Instance Variable	shunts	A dict of current sensing V elements with the pairs of nodes they connect.
Class Variable	debug	A `Bag` that gets set `True` for all instances to log info about each `setup` call.
Class Method	autoName	Undocumented
Method	setupResults	Undocumented
Method	fill	Undocumented
Method	nodeCheck	Call with the circuit building tool f and a sequence of nodes provided to this `Include` or `Subcircuit`.
Method	rawNetlist	Get lines of a raw netlist from a search hierarchy of possible sources.
Method	shunt	Call to insert a current-measuring shunt and add an entry to my `Elements` baton's dict of shunts.
Method	raw	See `Elements.raw`.
Method	iNode	See `Elements.iNode`.
Method	ground	See `Elements.ground`.
Method	sca	See `Elements.sca`.
Method	sca6	See `Elements.sca6`.
Class Method	_libDir	Undocumented
Method	_strippedLines	Undocumented
Method	_call_setup	Calls my `setup` method (almost always your override of that method, actually) and processes any return value.

t =

A Numpy vector of increasing simulation time points.

X =

A Numpy vector with the same length as t of source voltages.

filePath =

The full path of a file to be (over)written with t and X data. Any home directory symbol ("~") will be expanded. If None (the default), a new, unique temporary file path will be used.

keep =

Set True to keep the file after Python shuts down. The default is to automatically delete it, but you may want to keep it for study.

gain =

A scalar for amplifying the signal (default is 1.0).

def writeData(self, filePath, t, X):

Opens a new tempfile for writing and for Ngspice to read during this Python session. (Gets deleted when Python shuts down.)

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.
