Companies specializing in circuit board and system design-for-test (DFT) tools are pursuing a variety of strategies to serve test and debug applications based on innovations they announced over the ...

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 ...

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 ...

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 ...

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 ...
