Python scripting
Scripts can run sheet simulations, derive traces, and open temporary plot outputs without changing the saved schematic.
Module functions
get_sheet(sheet_name=None)Returns a schematic handle for run-local component overrides and simulations.
dc_source(value=0)Creates a typed DC source override.
ac_source(magnitude=1, *, phase=0, dc=0)Creates a typed small-signal AC source override.
sine_source(amplitude, frequency, *, offset=0, delay=0, phase=0)Creates a typed sinusoidal source override.
pulse_source(low, high, frequency, *, duty=50, delay=0, rise=0, fall=0)Creates a typed periodic pulse source override.
solver(*, method=None, preset=None, **options)Builds a validated solver configuration without raw `.options` text.
subplots(rows=1, cols=1, *, title=None, sharex=False)Creates a figure and one axis or a tuple of axes.
export_csv(filename, *signals)Downloads derived Signals that share an x axis as CSV.
plot(signal_or_x, y=None, *, label=None, color=None)Adds a Signal or x/y sequence to the default figure.
show(*, title=None, xlabel=None, ylabel=None, xscale=None)Opens the default figure as a script output tab.
Result, sheet, axis, and figure methods
sheet.component(refdes)Returns a run-local component override handle.
sheet.override(**components)Returns an independent sheet handle with scalar or typed-source overrides.
sheet.sweep(*, mode="product", **components)Creates a Cartesian component sweep that executes as one batch host operation.
sheet.run(*, save="all", solver=None, parameters=None, directives=None, timeout=15)Runs the sheet's configured analysis.
sheet.op(*, save="all", solver=None, parameters=None, directives=None, timeout=15)Runs an operating-point analysis.
sheet.tran(stop, *, step="10u", start=None, max_step=None, uic=False, save="all", solver=None, timeout=15)Runs a transient analysis.
sheet.ac(start, stop, *, points=100, sweep="dec", save="all", solver=None, timeout=15)Runs a linear, octave, or decade AC sweep.
sheet.dc(source, start, stop, step, *, save="all", solver=None, timeout=15)Runs a DC source sweep.
result.component(refdes)Returns the semantic signal groups saved for one component.
result.signal(expression)Returns an explicitly saved node voltage, default current, or semantic component signal.
component.signal(path)Returns one saved semantic signal using a component-relative group path.
result.to_csv(*expressions)Returns CSV text for selected signals, or every returned vector when no expressions are given.
result.export_csv(filename, *expressions)Downloads selected result signals as CSV, preserving real and imaginary AC columns.
result.v(net)Returns a node-voltage Signal.
result.i(refdes)Returns the component Model's declared default-current Signal.
signal.window(start=None, stop=None)Returns the samples inside an x-axis window.
signal.at(x, *, method="linear")Samples a Signal by linear interpolation or nearest point.
signal.mean(*, start=None, stop=None)Mean measurement; transient mean/RMS/integral use time weighting.
signal.rms(*, start=None, stop=None)Rms measurement; transient mean/RMS/integral use time weighting.
signal.min(*, start=None, stop=None)Min measurement; transient mean/RMS/integral use time weighting.
signal.max(*, start=None, stop=None)Max measurement; transient mean/RMS/integral use time weighting.
signal.pkpk(*, start=None, stop=None)Peak-to-peak measurement; transient mean/RMS/integral use time weighting.
signal.integral(*, start=None, stop=None)Integral measurement; transient mean/RMS/integral use time weighting.
signal.crossings(level=0, *, edge="both")Returns interpolated rising, falling, or all threshold-crossing x coordinates.
signal.fft(*, window="hann", detrend=True)Resamples adaptive transient data uniformly and returns a complex frequency-domain Signal.
signal.thd(fundamental, *, harmonics=10, start=None, stop=None)Computes total harmonic distortion from a transient window.
axis.plot(signal_or_x, y=None, *, label=None, color=None)Adds a Signal or x/y sequence to an axis and returns the axis.
axis.set(*, title=None, xlabel=None, ylabel=None, xscale=None)Sets pane labels and scale, then returns the axis.
figure.show(title=None)Opens the figure as a script output tab.
figure.savefig(filename, *, title=None)Opens the figure output and downloads all of its panes as one PNG.
