librosette 0.1.1

A fast, intelligent, and accessible layout editor

Rosette

A modern GDSII layout editor for integrated circuits. Fast. Intelligent. Accessible.

By PreFab Photonics.

Highlights

• Fast — A Rust core and GPU rendering that keeps you in the flow. From geometry operations to live preview, every layer of the stack is built for speed.
• Intelligent — AI-native from the ground up. Agent instructions and direct code access give LLM agents the context to design circuits alongside you.
• Accessible — A clean Python API, a modern desktop app, and documentation written for engineers. Professional tools without the learning cliff.

Quickstart

Requires uv and Python 3.11+.

mkdir my-chip && cd my-chip
uv init
uv add librosette
uv run rosette init

rosette init walks you through template and AI tool selection, then scaffolds your project with editable components, layer config, and agent instructions.

Commands

Command	Description
rosette init	Initialize rosette in current project
rosette build <design>	Compile a design script to GDS
rosette serve [design]	Start dev server with live preview
rosette run <file.gds>	View a GDS file

Run commands with uv run rosette <command>, or activate the venv first (source .venv/bin/activate).
