In earlier times, most of the gadgets and machines were quite big and some of them occupied a lot of space. In fact, first electronic general-purpose computer ENIAC occupied 1800 square feet of floor space. However, technological advancement led to the invention of compact devices and machines. Nowadays, machines and gadgets are not as huge as they used to be and are easy to maneuver. The compact size of new age gadgets and machines made them quite user-friendly and efficient. The technological advancements that contributed in making gadgets and devices smaller are an asset for many fields including science, medicine, education and business.

JTAG
As the size of the gadgets and machines decreased, creating an inbuilt circuit, which is responsible for the overall operation, became a tough task. Small circuits were difficult to design but techies came up with innovative ideas to invent small circuit boards that can fit inside various types of machines and devices. However, bigger challenge than conceiving these circuit boards was testing them for faults. Testing small circuit boards was a tedious task and to make this process less complicated, JTAG concept and boundary scan architecture was developed. This scan is basically accomplished for testing circuit boards for functional faults. JTAG is a cost effective testing technology and it has immensely helped in designing and creating small circuit boards for different types of machines.

This testing technology is efficient enough to deal with the challenges involved in the analysis of small circuit boards. The PCBs or printed circuit boards that are installed in various types of devices and instruments are tested for faults that can possibly hamper their operation with the help of JTAG boundary scan. This scan immensely helps in making sure that the circuit boards work properly and all the operational flaws are detected and resolved before the circuit boards are installed in any gadget or instrument. This testing method helps in assessing the faults in interconnects of PCBs and is quite popular for its accuracy. JTAG boundary scan is widely used in the automation world for testing circuit boards of different types of machines and instruments.

JTAG debugging tutorial has played a pivotal role in the invention of many high-tech devices and machines. This tutorial immensely helped innovators in understanding the pattern that they needed to follow in order to accomplish boundary scan successfully. By detecting this pattern, JTAG boundary scan debugging tutorial helped in finding the faults that may possibly hamper the operation of the circuit boards.
