Find the Best USB JTAG Programmer for Testing and Programming

Posted by davinmolli on March 10th, 2016

Ever since the advent of electronic devices, there has been a need to test them for programming and software. This has been done for decades now to look for chinks in these devices and find ways to improve the tech at the same time. While it is relatively simpler to test larger electronic devices, it is the smaller ones that cause a fair bit of trouble to the ones who are charged with testing them. And for such devices, a lot of the companies today employ boundary scan tests for accurate results.

For those who are not in the know of this, here’s a brief recap on what boundary scan actually is and how it came into effect. In 1985, there were a group of electronics companies who established the Joint Test Action Group (JTAG) consortium. This was done specifically to tackle the testing of small devices, and they formulated a specification to perform boundary scan tests on these devices. In 1990, this specification resulted in the formation of the IEEE 1149.1 standard, which devised the details of access to any chip with the JTAG port.

The birth of boundary scan has enabled engineers around the world to perform extensive debugging on a system through a few dedicated test spins. In these test spins, signals are serial-wise scanned into and out of the I/O cells to control the device’s inputs and test the outputs under numerous conditions. Other than this, JTAG testing has enable developers and engineers to do a whole host of other things that has resulted in making JTAG testing incredibly popular. Here are some of the benefits that JTAG boundary scanning offers:

The cost of test generation can be reduced significantly if you use a JTAG boundary test. That is because it provides the equivalent of in-circuit testing without the need of pumping more money on it separately.
 JTAG boundary scan technology also greatly reduces test time, especially in diagnosis.
Implementing JTAG boundary test can also reduce design irrigation
The cost effectiveness that the JTAG boundary scanning affords also helps you get a quick ROI.

With such incredible benefits associated with JTAG boundary testing, you need to implement it to believe it. The next thing you need to do is hire a leading company that is associated with JTAG boundary scanning, and who will offer you the best when you buy USB JTAG software. And to implement that software all you need to do is research and find the best USB JTAG programmer. So, don’t wait any longer. Implement the JTAG boundary scan for all your small device testing.
