This shift-register forms a path around the periphery or the boundary of the semiconductor device. The entry and exit points of the shift register are connected to the TDI and TDO pins ...

WebThe boundary scan cells then record the actual outputs and the resulting inputs on other pins, and the results are sent to the PC software for analysis. In this way, nets suffering from open-circuit, short-circuit or “stuck-at” faults are located, and key devices are confirmed to be operational and correctly placed. WebNov 9, 2024 · The boundary scan or JTAG (Joint Test Action Group) is used to verify the designs and test PCBs for any defects. A JTAG-compatible IC includes boundary-scan cells between a core logic and the signal Input/Output (IO). These boundary scan cells can be either input only, output only, or bidirectional cells.
