Are you new to boundary scans and JTAG? Take a look at this quick guide to understanding what exactly it means, and why JTAG is essential.

JTAG stands for Joint Test Action Group. When referred to as part of a boundary scan test, it means computer chips and electronic devices that are made according to this group’s standards. This does not apply to every device, but many devices are JTAG-enabled to ensure that the device can be checked on the pin level at any stage of production.

You use JTAG when performing boundary scans. A boundary scan is a simple test that checks connectivity between pins on an electronic chip. This is done during various stages of production in order to make sure that there are no bugs in the electronic devices. Making sure that an electronic device is JTAG-enabled is simple. Performing a boundary scan test requires no coding knowledge, and can be achieved with a simple plug-and-play JTAG controller. Flynn Systems provides top of the line JTAG controllers to perform your boundary scan tests so that you easily can make sure your chips and devices are working as expected.

JTAG devices and boundary scans are useful for a wide variety of reasons. At any stage of development, you’ll want to perform a boundary scan as part of your debugging process. It’s one of the easiest ways to see quickly if there are any hardware issues. JTAG is much shorter than other testing options, and shorter tests mean that more devices can be developed in the same amount of time. This also saves your company money, as you can debug before it’s too late for any serious issues to arise.

There’s a reason that engineers prefer JTAG and boundary scan testing over any other options. Contact Flynn Systems today to learn more about JTAG and how we can help you perform your boundary scan tests.
