Automating Boundary Scan Testing Electronic Design

WebThe process of boundary scan can be most easily understood with reference to the schematic diagram shown in figure 1. All the signals between the device’s core logic and the pins are intercepted by a serial scan path known as the Boundary Scan Register (BSR) which consists of a number of boundary scan ‘cells’.
