About

Copperhead is an open source AI engineering platform that helps hardware teams design, verify, and ship circuit boards. You describe a change or provide a product brief, and the agent edits real KiCad files, updates the documents that reference them, and runs KiCad’s own checks until they pass. Its end-to-end workflow moves through specification, architecture, parts selection, schematic, layout, outputs, firmware, and development planning, with each stage required to leave a real artifact on disk before the next begins. Gates verify budgets, subsystem reasoning, datasheet-backed part numbers, ERC-clean schematics, DRC-clean layouts, generated Gerbers, firmware sources, and written bring-up plans. Copperhead is also designed for existing boards: point it at a KiCad repository, initialize the project, and ask for changes. Edits are surgical changes to KiCad source files, keeping diffs small and reviewable while untouched portions remain unchanged.

About

One animated circuit is worth a thousand equations and diagrams. Animations of voltages, currents, and charges are displayed right on top of the schematic, providing great insight into circuit operation. The real-time circuit simulation engine is custom-built for speed and interactivity. Easy one-click simulation, from simple resistors and logic gates to complex transistor-level oscillators and mixed-signal designs. While the simulation is running, you can flip switches, adjust potentiometers, tune LED current limiting resistors, ramp up input voltages, etc. The circuit will immediately respond to your changes, in real time. Mini-waveforms on top of schematic wires look different for digital and analog signals. Constant analog voltages are shown as numbers, digital wires are color-coded. Any pair of time-domain signals may be plotted in the XY mode. The oscilloscope scale and grid ticks are auto-updated to convenient values as the data changes.
