The role of JTAG debugging tutorial has certainly been big in creation of some of the most high-tech devices and machines.

1. Know about JTAG Concept and Boundary Scan
Technology has changed our lives and now we have an invention to rely on for almost every
routine task. From the mobile phones in our bags and pockets to the high-tech machines and
equipment that are used in commercial facilities, technology has certainly made the impossible
possible. There is a lot of effort behind each and every technological marvel that you use or have
known about. Almost every device or machine has a very complicated working mechanism that
has been designed after years of research and hard work. The work behind the technology, which
you are using in your daily life, is tough and time taking.
The advancement in technology led to the development of devices that are smaller in size. As the
size of the devices and machines decreased, it made it difficult to create an in-built circuit in
them, which is responsible for the overall operation. The minute circuits were difficult to design
and fabricate and were even more typical to test. This made it essential to develop JTAG
concept and boundary scan architecture. This scan is basically done for testing these circuits
for functional faults. This testing technology is cost effective and is efficient enough to deal with
the challenges of examining minute circuit boards.
The PCB’s or printed circuit boards, which are installed in various types of devices and
instruments, are tested for any obstruction that can possibly hamper their working. JTAG testing
is accomplished on the printed circuit boards for making sure that the circuits work properly
during their operational life. This testing method competently helps in assessing the faults in
interconnects of PCB’s and is quite famous in the world of automation. The test has been
designed after years of research and it has certainly revolutionized the world of technology.
The role of JTAG debugging tutorial has certainly been big in creation of some of the most
high-tech devices and machines. This tutorial helped innovators understand the pattern that they
had to follow to accomplish boundary scan successfully in order to find out about the faults that

2. may hamper the functioning of the circuit boards. In case, you are willing to make a career in this
field then it is essential to take up at least boundary scan basic tutorial. This tutorial will be
immensely helpful for you. You should get some professional help also to understand the major
pros and cons of boundary scan and JTAG testing.
