Module spice 

ngspice integration for golden reference generation.

This module provides functions to run ngspice simulations and extract output for comparison with WDF results.

Requirements

ngspice must be installed and available in PATH:

• macOS: brew install ngspice
• Ubuntu/Debian: apt install ngspice
• Windows: Download from ngspice.sourceforge.io

Example

use pedalkernel_validate::spice::{SpiceRunner, SpiceConfig};
use pedalkernel_validate::signals;

let config = SpiceConfig {
    sample_rate: 96000,
    oversample: 4,
};

let runner = SpiceRunner::new(config);

// Generate input signal
let input = signals::sine(config.internal_rate(), 1000.0, 0.1, 1.0);

// Run SPICE simulation
let output = runner.simulate(
    "circuits/nonlinear/diode_clipper.spice",
    &input,
    "v_out"
).unwrap();

Structs

SpiceConfig

Configuration for SPICE simulations.

SpiceDeviceOp

One device’s DC operating point as reported by ngspice’s .op / show.

SpiceOpSnapshot

A full ngspice .op snapshot: per-device operating points plus node voltages.

SpiceRunner

Runner for ngspice simulations.

Enums
