#Core capabilities

• SPICE-like parsing with blank lines, comments, directives, duplicate-name detection, and engineering suffixes (k, meg, m, u, n, p).
• Resistors, capacitors, inductors, diodes, independent current sources, and independent voltage sources.
• Dense MNA with partial pivoting, residual diagnostics, singular-system reporting, deterministic node ordering, and circuit topology inventory.
• DC operating-point analysis with explicit warnings for DC approximations.
• Complex MNA for frequency-domain AC analysis, gain curves, impedance helpers, and transfer-function models.
• Backward-Euler RLC transient analysis, companion models, traces, settling metrics, and signal-processing utilities.
• Sparse matrices with conjugate-gradient/Jacobi solvers, matrix diagnostics, topology graph views, and deterministic parameter/sensitivity analysis.
• Engineering design helpers for component selection, uncertainty propagation, netlist editing, validation, and machine-readable reports.
• CSV, text, and Markdown output that can be consumed by a CLI or a notebook.

#Quick start

let circuit = @spice.parse_netlist(
  "V1 in 0 10\nR1 in out 1k\nR2 out 0 1k",
)
let result = @spice.dc(circuit)
println(result.summary())
