"Boundary scan, also known as JTAG (Joint Test Action Group), is a test technique that involves the integration of shift register latch cells, known as boundary scan cells, into each external connection of boundary scan compatible devices. These cells allow for the testing and debugging of integrated circuits (ICs) and interconnects on a PCB."
