Spice Sim

Adds ngspice simulation testbenches to Zener PCB designs when you need to validate circuit behavior before fabrication. Creates focused test files with PULSE or PWL sources, runs transient analysis, and exports waveforms to SVG. Handles the full flow: checking if your design is simulation-capable, wiring SpiceModel instances into leaf components when vendor models are missing, and structuring the testbench with proper control blocks. The pattern keeps one behavior per file, startup or protection thresholds or current limiting, which makes debugging cleaner than cramming everything into a single sim. Useful if you're already working in Zener's Python-like HDL and want quick spice verification without leaving the toolchain.
