SPICE Circuit Modeling

Overview

Use this skill to make a SPICE deck an oracle: a frozen, reproducible, numerically qualified reference that other artifacts (a KiCad schematic, golden fixtures, a realtime DSP model) are checked against. "The simulation ran" is never the finish line. The deck must be correctly transcribed, built from labelled and hashed models, numerically converged for the metrics that matter, robust to statement order, in the intended operating state, and reproducible on another machine.

Related skills (load them for their parts; do not duplicate them here):

• circuit-to-dsp: turning the frozen oracle into a realtime model, choosing solvers, integrators and rates, and designing validation gates. Its references/circuit-reference-validation.md is the authority for comparing DSP against a circuit reference: the claim-specific source hierarchy and four result axes, measurement contracts, golden captures, drift and release integrity.
• guitar-dsp: guitar-specific signal-chain, drive-feel, tone and product decisions.
• dsp-engineer: spectral measurement methodology (windows, coherent tones, error metrics).
• juce-plugin: plugin build, lifecycle and host validation.
