spice3

pip install spice3 → import spice.

Circuit simulation for Python, powered by Dune — a Rust engine derived from Berkeley SPICE3f5 and validated circuit-by-circuit against ngspice as numerical oracle.

Status: pre-alpha. This release reserves the package name while the engine's first public version is being finished. The API below works today but may still change.

from pathlib import Path
import spice

result = spice.simulate(Path("rc.cir"))
plot = result.plot("Transient Analysis")
df = plot.df()          # polars DataFrame, scale column first
v2 = plot.column("v(2)")  # zero-copy, read-only numpy array
  • Every SPICE3f5 analysis: .op, .dc, .tran, .ac, .pz, .noise, .disto, .tf, .sens — plus the periodic steady state of driven circuits (.pss, shooting–Newton; spice.pss()).
  • All SPICE3f5 devices, including BJT (Gummel–Poon), MOS levels 1/2/3/6, BSIM1/BSIM2, JFET, MESFET, switches and both transmission lines.
  • Results as polars DataFrames (pandas optional) and zero-copy NumPy arrays; complete type annotations (py.typed).
  • Schematics as decks: spice.pic.extract() reads the netlist of an rpic figure drawn with the dune prelude, spice.simulate() runs it and spice.pic.render() draws it as SVG (with typeset $...$ labels).
  • Faithful netlist semantics: decks that run under spice3 -b or ngspice -b run here, with structured, span-carrying errors.

The engine, corpus and oracle harness live in the Dune repository. BSD-3-Clause, © André Leite and The Regents of the University of California.
