Start with a connection table
For a small interface board, record power rails, permitted voltage levels, connectors, pin assignments and mechanical limits. Ask AI to turn these inputs into a net table and a list of unresolved questions. Require unknown values to be marked and pin numbers to be checked against the exact manufacturer document revision. Keep the table with the project.
Check intent before routing
Build the schematic, assign footprints and run ERC. Separately review polarity, connector mating views, decoupling and symbol-to-package pin mapping. ERC checks configured electrical rules; it does not establish that the selected component is suitable. AI can draft review questions, but answers must point back to the schematic and component documentation.
Make fabrication constraints explicit
Before routing, set stackup, clearances and track dimensions for the chosen manufacturing process. Transfer the schematic to the PCB, place components and review current return paths. After edits, refill zones and run DRC. Record a reason for every accepted exception; an AI suggestion to suppress a warning is not an engineering justification.
Produce a review package
Keep source files, ERC/DRC reports, the BOM and fabrication outputs under one revision. Open the Gerbers in a viewer and inspect outline, drilling, mask and markings. Compare the result with the original connection table. The release is ready for review when another engineer can repeat the checks and identify every remaining assumption.
Checks before accepting the result
A useful AI output is a checkable table and a review checklist. Release evidence comes from the design and repeatable checks.
