WebThe 1149.1 boundary-scan architecture and four-wire test bus interface is shown in Figure 1. The test architecture consists of a test access port (TAP), two separate shift register paths for data (DREG) and instruction (IREG) and a boundary-scan path bordering the IC’s input and output pins. The boundary-scan path is one of two required scan ... WebBoundary scan is a method for testing interconnects on PCBs and internal IC sub-blocks. It is defined in the IEEE 1149.1 standard. For boundary scan tests, additional logic is added to the device. Boundary scan cells are placed between the core logic and the ports.
