Circuit Design Python Packages

perfboard-studio

Design circuits on perfboard the way you would on a PCB — netlist-driven placement and routing, perfboard-specific DRC, LVS, and a soldering guide with measurement checkpoints.

squadds

A validated design database and simulation workflow software for superconducting quantum hardware

ltspice-mcp

MCP server giving LLMs the ability to design, simulate, and analyze SPICE circuits via LTSpice and NGspice

spydrnet

A flexible framework for analyzing and transforming FPGA netlists. Official repository.

akcli-kicad

AI-native schematic design agent, purpose-built for KiCad (zero-dependency pure-stdlib Python CLI): author and edit .kicad_sch from JSON op-lists with net-diff safety rails, run ERC/design/intent/BOM checks, simulate on KiCad's bundled ngspice, source real parts and fetch datasheets, and import Altium .SchDoc/.SchLib/.PcbDoc read-only into KiCad

circuit-mcp

MCP server giving LLMs the ability to design, simulate, and analyze SPICE circuits via LTSpice and NGspice

ngspice-mcp

MCP server giving LLMs the ability to design, simulate, and analyze SPICE circuits via LTSpice and NGspice

spicebridge

MCP server that gives AI assistants direct access to ngspice circuit simulation — design, simulate, and verify circuits through natural language

strider-dna

A Python library for nucleic acid thermodynamics, kinetics, and DNA/RNA circuit design with end-to-end simulation pipelines.

perfstudio

Design circuits on perfboard the way you would on a PCB — netlist-driven placement and routing, perfboard-specific DRC, LVS, and a soldering guide with measurement checkpoints.

analog-daddy

This library is an attempt to make transistor sizing for Analog design less painful.

boardsmith

Text prompt → KiCad schematic, BOM, and firmware. No templates — real wired circuits with computed values.

qcd-gym

Quantum Circuit Designer: A gymnasium-based set of environments for benchmarking reinforcement learning for quantum circuit design.
