Boundary scan is a method used to test interconnects (lines) on internal sub blocks of printed circuit boards or integrated circuits. Boundary scan is also widely used as a debugging method to observe the pin status of integrated circuits, measure voltage, or analyze sub blocks inside integrated circuits.
