The .pss request (see Circuit::pss).

Fields

freq: Option<f64>

Fundamental frequency in Hz; None takes it from the periodic sources (the greatest common divisor of their frequencies). Without periodic sources (an autonomous oscillator) it is a guess of the period’s inverse, and None estimates it from the stabilization transient.

tstab: f64

Stabilization time: a plain transient runs from 0 to the first period boundary at or after tstab (at least one period) before the shooting starts there.

osc_node: Option<String>

ngspice’s oscillation node. A driven circuit only checks and reports it; an autonomous one (no periodic source) needs it: its phase condition holds this node at its value on a rising mid-range crossing, and its crossings estimate the period.

points: usize

Samples per period in the time-domain plot (the plot has points + 1 rows, both ends included, like ngspice’s).

harmonics: usize

Rows of the frequency-domain plot: DC plus harmonics − 1 harmonics (ngspice’s count).

max_iter: usize

Most shooting iterations (adaptive period transients).

steady_coeff: f64

Scale of the convergence tolerance: converged when every unknown has |x(t₀+T) − x(t₀)| ≤ steady_coeff · (RELTOL · peak + VNTOL|ABSTOL), peak its largest magnitude over the period.

uic: bool

Run the stabilization transient with UIC.
