Symbol and Footprint Database for Electronic Components by Agentic Recognition and Generation

Research LLM Agents

Merged summary

TL;DR - SFgen uses multimodal LLM agents to recognize and generate PCB component symbols and footprints, reducing reliance on error-prone manual library creation. It also powers SFnet, an expanding database currently covering 1,000 components.

  • SFgen reports 86% accuracy for symbol generation.
  • Footprint generation achieves 80% accuracy.
  • The resulting SFnet database supports future automated PCB design generation.
