丰富且可识别的元件库是印刷电路板(PCB)设计与生成的基石。传统上,工程师手动创建符号和引脚封装并设计PCB原理图,既耗时又易出错。利用多模态大语言模型(MLLMs),我们开发了SFgen,一种用于电子元件符号和引脚封装的智能识别与生成流程。SFgen符号生成准确率达86%,引脚封装生成准确率达80%。我们用该方法创建了SFnet,一个符号和引脚封装数据库,现有1000个元件且不断扩充,为PCB设计自动生成奠定基础。
英文摘要
A rich and recognizable component library is the cornerstone of printed circuit board (PCB) design and generation. Traditionally, engineers manually create symbols and footprints and design PCB schematics, which is time-consuming and error-prone. Leveraging multimodal large language models (MLLMs), we develop SFgen, an agentic recognition and generation flow of symbol and footprint for electronic components. SFgen achieves 86% accuracy for symbol generation and 80% accuracy for footprint generation. We use the SFgen method to create SFnet, a database of symbols and footprints. It now has 1000 components and is expanding constantly, which lays the foundation for automatic generation of PCB designs.
