Get JTAG Boundary Scan Architecture And Test Interconnects Without Probes

Posted by davinmolli on February 12th, 2016

JTAG boundary scan was introduced in the early 1990s. Facilitation of in-site simulation and debugging was the main the reason for developing the common standard of JTAG or Joint Test Action Group. Highly demanded for testing electronic circuits, JTAG boundary scan tool, is nowadays essential for building cutting-edge technology products with a wide degree of testability. It is a test system that tests interconnects on the printed circuit boards or sub-blocks inside the integrated circuits. Apart from the same, JTAG boundary scan test tool is also used as a debugging method to measure voltage or to observe states of integrated circuit pins. Ideal for testing complex electronic circuits in a limited test access, JTAG boundary scan test system is efficient to debug embedded systems that may lack other debug-capable communication channels.

You must have heard about the ‘bed of nails’ technique. In the bed of nails testing technique, innumerable pins were inserted into holes in epoxy phenolic glass cloth laminated sheet that contacted test points on a PCB. Moreover, the process included pressing the DUT (device under test) manually or through vacuum downwards to the nails. As a result, the pressing downward of DUT created small dents on soldered connections of the PCB. Prior to JTAG boundary scan test, people used ‘bed-of-nails’ technique that was extremely hard to use and complex. But, with the evolution of boundary scan technique, it became easy and quick to carry out the tests. And now, JTAG boundary scan is widely demanded for applications like CPLDs, microprocessors, FPGAs, SERDES, DSPs, ASICs, bus logic, telecom encoders, PHYs and Bridges (PCI/PCIe). Owing to the flexibility of JTAG boundary scan technique, it is widely utilized in development and production applications. Moreover, it can also be used for system level test, BIST access, Flash programming, CPU emulation, FPGA / CPLD programming, and memory testing.

So, if you want to test interconnects without making use of test probes, get JTAG boundary scan architecture right away!
