Boundary scan
In boundary scan testing, analogue and digital components for which no direct physical access is provided are tested. This is usually the case with densely populated or multi-layer printed circuit boards, and especially with integrated circuits, if not all contacts can be accessed. The basis is a test logic integrated in the device. The boundary scan is used to determine whether the correct device has been installed and correctly soldered.
