For some time, engineers have followed the IEEE 1149.1 standard, also known as “boundary-scan,” to create test structures on pc boards and in complete systems. Unfortunately, once products leave a ...

Boundary scan offers clear advantages over technologies that require physical contact with a unit under test. It is also useful for ferreting out faults among the expensive, advanced semiconductor ...

To ensure customers receive high-quality products, engineers must consider testing strategies before they even think about a schematic diagram. These days, most engineers realize boundary scan ...

Maybe you should try boundary scan testing now that your continuity buzzer has died. Most engineers are familiar with the theory of boundary scan testing, but what about having actual hands-on ...

Bigger designs with hundred of cores are creating an explosion in the volume of scan test data, significantly bumping up the amount of time spent on test. That raises the cost of test, forcing ...

Some new design-for-test (DFT) technologies are difficult, expensive, or risky to implement but offer significant benefits. Other technologies are easy to implement but offer minor improvements. The ...
