Boardwise Turns Board Mistakes Into Permanent Review Checks

Each problem found on a real board becomes a versioned check in Boardwise's AI design review, with its own regression test so it can't quietly come back.

Thesis connection

When every escaped board defect becomes an automatic check, the next design review catches it before a board is built.

Boardwise is an open-source AI reviewer for circuit board designs, and its v0.5.15 release shows a habit worth copying. Each new check in the release came from feedback on a real board. One fixes how it measures high-voltage spacing between copper at the same electrical potential. Another tracks current-carrying capacity across copper areas that are electrically joined. A third keeps exceptions an engineer took from a datasheet and applies them to every later review instead of forgetting them.

The process around those checks is the interesting part. A problem that slipped past review becomes a rule, the rule gets its own regression test, and nothing ships until the full suite of 6,242 tests passes, along with mutation tests that confirm the tests would catch a broken rule. Every finding points to specific nets, pins, and copper shapes. When the tool proposes a change to the design, it shows a preview, waits for approval, reads the design back, and reviews it again, so a successful edit command is never taken as proof the board is right.

You don't need Boardwise to use the idea. The next time a defect reaches a built board, write it up as a check your design review runs automatically, in addition to the line in the postmortem. Most hardware teams have a few defects they've found more than once, and those are the place to start.
