AI PCB Design Generator

Automated PCB Design Generator

This workflow automates the process of designing a compact IoT sensor Printed Circuit Board (PCB). It acts as an end-to-end electronic engineering assistant that combines architectural planning, component verification, KiCad file generation, and version control integration to produce a comprehensive board design.

Workflow Steps

1. Manual Trigger: You input a detailed design request describing the board's specifications, components, and physical constraints.
2. Architecture Generation: An AI agent analyzes the request and generates a thorough architecture document. This includes the subsystem breakdown, power tree, Bill of Materials, netlist, layer stackup, design rules, and routing constraints.
3. Component Verification: A dedicated AI node verifies the architecture against real-world component datasheets fetched from the internet, confirming pin numbers, application circuits, and protective requirements.
4. Format Research: Concurrently, an AI agent researches the exact KiCad file format syntax and footprint libraries required for the specified components.
5. Final Engineering and File Creation: A final AI agent compiles the verified architecture and syntax research to programmatically generate valid schematic and board files.
6. GitHub Integration: The workflow automatically pushes the finalized KiCad design files directly to a specified GitHub repository.

Prerequisites

1. A Needle platform account with access to AI nodes and file creation tools.
2. Internet search and web browsing tools enabled to fetch accurate datasheet information.
3. An authenticated GitHub connection to push the finalized design files.
4. Familiarity with PCB design concepts and KiCad software.

Input and Output Data

Important Notes

1. The workflow relies heavily on live internet access to fetch the most accurate and up-to-date datasheet information.
2. The architecture output is designed to be highly detailed, providing a solid foundation for physical board manufacturing.
3. Generating, formatting, and verifying these complex text-based KiCad files requires multiple steps, so running this workflow may take several minutes.
4. The automated GitHub step ensures your generated hardware designs are immediately version-controlled and ready for review.
