The invention of the Printed Circuit Board (PCB) led to different breakthroughs in the electronic world. PCBs are the crucial basis for virtually every electronic device and find application in several fields, ranging from medical to automotive and IoT to aerospace. An extensive number of components find a place on the topmost or the bottom layer, and they are connected following an intricate tangle of connections. Two types of files are essential for understanding how a PCB works: placement (describes the layout of components on one layer) and schematic (reports the connections and the pins for each component). Manually testing a PCB requires looking for a specific component or connection in a placement or schematic file, which in turn requires the tester to look alternatively between the board and the manual.
