Ryan Malloy	de7a29c69e	Add auto-schematic generation from SPICE netlists ... Parse netlists into component graphs and render circuit diagrams via SchemDraw. Two layout strategies: loop layout for simple 2-terminal circuits (RC, RL, voltage divider) and labeled grid for complex circuits with active devices (BJT amplifiers, MOSFET). Backend: netlist parser, schematic engine, POST API endpoint. Frontend: SchematicViewer with zoom/download, stacked cell layout showing schematic + SPICE editor + waveform simultaneously.	2026-02-13 06:07:30 -07:00
Ryan Malloy	8abd7719bf	Initial SpiceBook MVP: notebook interface for circuit simulation ... Phase 1 implementation with ngspice backend and Astro/React frontend: Backend (FastAPI): - ngspice subprocess engine with custom .raw file parser - Notebook CRUD with .spicebook JSON format (filesystem storage) - Simulation endpoints (standalone + cell-in-notebook) - SVG waveform export endpoint - 18 REST API routes, 5 passing tests Frontend (Astro 5 + React 19): - Notebook editor as React island with Zustand state management - CodeMirror 6 with custom SPICE language mode (syntax highlighting for dot commands, components, engineering notation, comments) - uPlot waveform viewer with transient and AC/Bode plot modes - Markdown cells with edit/preview toggle - Notebook list with card grid UI - Dark theme, Tailwind CSS 4, Lucide icons Infrastructure: - Docker Compose with dev/prod targets - Caddy-based frontend prod serving - 3 example notebooks (RC filter, voltage divider, CE amplifier)	2026-02-13 01:44:38 -07:00
