Module ac_accuracy 

Structs

AcResult

Full AC-accuracy result for one circuit.

AcThresholds

Thresholds for grading the AC dimensions. Informative (localizes which dimension carries the error), not a hard CI gate.

FreqPoint

One frequency-sweep point: WDF-vs-golden AC gain at that frequency.

HarmonicError

One harmonic’s level, WDF vs golden, expressed in dBc (relative to the fundamental) so it is level-independent by construction.

Enums

AcVerdict

The AC-fidelity verdict for one circuit — which dimension carries the error.

Constants

HARMONIC_FLOOR_DBC

A golden harmonic weaker than this (relative to the fundamental) is treated as absent (below the simulator noise grass): its per-harmonic error is not scored for the verdict, so ngspice noise bins don’t masquerade as shape error. −80 dBc sits above ngspice’s typical noise grass yet below a real diode/BJT harmonic.

HARMONIC_ORDERS

Harmonic orders scored per-tone (2nd through 5th).

Functions

evaluate

Decompose the WDF-vs-golden AC error into level / shape / harmonics / response and reach a verdict.

response_tilt_db

Response tilt: max−min over the finite per-frequency gains.
