## What SpiceBook Does

SpiceBook is a notebook interface for SPICE circuit simulation. Each notebook is a sequence of cells — markdown for documentation, SPICE netlists for circuits, and auto-generated schematics and waveform plots for visualization.

You write a netlist, run it against ngspice or LTspice, and see the results inline. No file management, no separate plotting tools, no context switching between editor and simulator.

  <Card title="Dual Engines" icon="setting">
    Choose ngspice (built-in) or LTspice (via [mcltspice](https://mcltspice.warehack.ing)) per notebook. Same netlist format, different solver characteristics.
  </Card>
  <Card title="Waveform Plots" icon="line-chart">
    Transient, DC sweep, and AC analysis results render as interactive SVG plots with an oscilloscope display mode.
  </Card>
  <Card title="Auto Schematics" icon="puzzle">
    SPICE netlists are parsed into circuit diagrams automatically — resistors even render with IEEE zigzag symbols and 4-band color codes.
  </Card>
  <Card title="Embeddable" icon="laptop">
    Any notebook can be embedded on a third-party page via iframe. Viewers can run simulations directly in the embed.

## How It Fits Together

SpiceBook is part of the [warehack.ing](https://warehack.ing) project family. It pairs with [mcltspice](https://mcltspice.warehack.ing), an MCP server that gives AI assistants access to LTspice simulation — notebooks created by mcltspice are viewable and editable in SpiceBook.
