Flynn Systems developed a proprietary debugging software known as . This software allows the user to pinpoint specific bugs and increases visibility to JTAG testing. End users are able to access pins by wiggling or single stepping. This also allows them the ability to make changes to the test properties allowing a greater ability to […]

There are many different options out there to be testing boards when it comes to the design and manufacturing process of various products. However, we believe that using a boundary scan/JTAG test is the best way to test your boards and have compiled a few reasons why.  There are quite a few restrictions that are […]

In the world of every evolving and changing technology, boundary scan has played a large part in getting new items to the market. Boundary scan was created in an effort to make accessibility to testing multiple boards with a single system. To help you better understand why you should make the switch to boundary scan […]

New technologies in aerospace are constantly being built, tested, approved and launched. For example in 2019, Virgin Orbit launched LauncherOne, outfitting a Boeing 747 to launch the 70ft long rocket from its left wing into outer space. The rocket successfully entered space and the plane returned back to solid ground to fly again another day. […]

In an age where technology is king, electric systems have become part of everyday life. From our smartphones to medical equipment every piece of technology has been able to advance, thanks to rapid changes in how we work with electric systems. Innovation and creation are only able to be implemented in society if they have […]

Engineering has many different branches that students can expand into as they complete their college degrees and begin searching in the field for a position. Within the world of electric engineering is the smaller yet essential area of electronic engineering.  This area of study can be found at universities like USC and the University of […]

Mid-state shorts are a major problem that often goes undetected by typical boundary scan connectivity tests is mid-state/resitive shorts. Flynn Systems recognized this “hole” in boundary scan testing and was the first boundary scan test company to test for mid-state shorts, improving test fault coverage.

If a chain of devices consisted only of boundary scan (JTAG) compliant devices, there would not be too much testing required. However, boards today contain complex, non-JTAG devices that interact with the boundary scan devices. Testing just the JTAG devices on the board is always an option. However, developing a test that takes into account […]

Once a board developer passes along the new board and all related files and procedures to a test developer, the boundary scan test process can begin. We recommend including the TAP Integrity Test at the beginning of your interconnect test because the TAP contains pins associated with the test access controller, e g., the TAP […]

Chip manufacturers are now producing multichip modules (MCMs) that may include two or more arrays of devices within a single package. These modules can be tested using JTAG test pattern generation of the devices while on a PCB. To incorporate JTAG testing of MCMs there are several things that are needed: a netlist of the […]
