Analog Canvas
Local-first, connectivity-aware web schematic editor that imports structural SPICE, exports deterministic SPICE and Spectre netlists, and connects agents through the same typed edit model.
What it does and how it connects
Analog Canvas is a local-first, connectivity-aware schematic editor for the web. It supports drawing and organizing hierarchical circuits, importing structural SPICE, exporting deterministic SPICE and Spectre netlists and vector SVG and PDF, and publishing selected work to a Community Gallery.
Editing is connectivity-aware: devices are placed, wires routed, crossings distinguished from junctions, nets labeled, and multi-object edits undone as a unit, deriving physical networks from completed wire edits while keeping logical labels and unrouted import intent explicit. Each schematic is authored as a reusable Cell with independent Cell Pins and hierarchical blocks.
Agents connect through the same typed edit model the editor uses, via a version-pinned stdio MCP adapter, an HTTP Agent Kit, and a published OpenAPI contract. The hosted editor also provides saved simulation source folders and pinned ngspice, SKY130, and SG13G2 profiles for qualified OP, DC, AC, TRAN, and Noise runs, and a Windows desktop preview is linked from the README.
