OpenPlayer now generates its KiCad schematic from a Python description of the board's parts and connections. Instead of editing the schematic as the only source of truth, the project can rebuild it from a netlist, the structured list of which component pins must connect.
The generator reads KiCad's installed symbol libraries, places each component at a fixed coordinate, labels every used pin, and marks unused pins as intentionally disconnected. It writes both the schematic and project files for KiCad 10. The generated files remain ordinary KiCad documents, so an electrical engineer can still open them, run electrical checks, and inspect the drawing before layout.
This approach is strongest for carrier boards assembled from known modules, where connectivity changes more often than circuit topology. A text diff can show that a signal moved from one pin to another, and a clean checkout can reproduce the drawing without a person dragging wires. The open question is whether OpenPlayer will add a check that regenerates the schematic and fails when committed output differs, because generation without that check still allows the code and drawing to drift apart.
