Some test patterns were simply camera feeds of physical cards, but if you wanted the most accurate and reliable test patterns you’d need a Philips pattern generator which created the pattern ...

Hierarchical test also moves the vast majority of the DFT and ATPG work earlier in the design cycle, before the top-level design is complete. But there are also significant, though non-intuitive, ...

Test compression sounds like magic. Read on to learn how this trick is done.Large, complex ICs are viable because their design meets test as well as functional requirements. Design ...

The Imaging Science Foundation (ISF) has released some free 4K test patterns for B&W levels and geometry/resolution. This is just in time to meet up with the new 4K displays hitting the market.

Let’s get back to test patterns. The PRBS31 (pseudo-random binary sequence, 231-1) pattern includes every permutation of 31 bits. That means it has a billion edges, each preceded by a unique bit ...
