11.1.8.2. WaveForm¶
This module implements classes to handle analysis output.
-
class
PySpice.Probe.WaveForm.
AcAnalysis
(simulation, frequency, nodes, branches, internal_parameters)[source]¶ Bases:
PySpice.Probe.WaveForm.Analysis
This class implements an AC analysis.
-
property
frequency
¶ Return an Numpy array for the frequency abscissa

class
PySpice.Probe.WaveForm.
Analysis
(simulation, nodes=(), branches=(), elements=(), internal_parameters=())[source]¶ Bases:
object
Base class for the simulation output.
Depending of the simulation type, the simulator will return waveforms as a function of
time
frequency
sweep
…
and corresponding to
a node’s voltage
a source’s current
…
The name of a waveform is
node’s voltage: node’s name
source’s current: source’name
…
If the waveform name is a valid Python identifier, then you can get the corresponding waveform using:
analysis.waveforme_name
else you have to use this fallback:
analysis['waveforme_name']
Examples of usages:
# Operating point analysis for node in analysis.nodes.values(): print('Node {}: {:5.2f} V'.format(str(node), float(node))) for node in analysis.branches.values(): print('Node {}: {:5.2f} A'.format(str(node), float(node))) # DC sensitivity analysis for element in analysis.elements.values(): print(element, float(element)) # Plot the voltage of the "out" node plt.plot(analysis.out.abscissa, analysis.out)
Public Attributes:
nodes
Dictionary for node voltages indexed by node names
branches
Dictionary for branch currents indexed by source names
elements
Dictionary for elements …
