About
Trace is an AI-native PCB design platform that takes hardware teams from idea to manufactured board. It combines professional schematic capture and PCB layout tools with intelligent agents that understand hardware in context. Users describe what they want to build in natural language, and Trace can research the problem, generate hierarchical multi-sheet schematics, parse datasheets, suggest components, check real-time availability, place parts, route multi-layer boards, tune matched-length signals, and run ERC, DRC, and design reviews. Its component library includes more than 30,000 symbols and footprints, with sourcing data from major distributors. Plan Mode researches complex tasks, asks clarifying questions, creates a step-by-step plan, and executes only after approval, while TraceRules preserves component preferences, layout constraints, and manufacturing targets across conversations.
