Test compression technology was invented to address the problem of escalating test-pattern size. Compression allows more test vectors to be applied to an IC in a shorter time and with fewer tester ...

About a dozen years ago, the world of test had reached an economic impasse: most digital designs had become sufficiently complex that standard scan testing techniques were no longer cost-effective.

For the past five years, the cost of test has prevailed as the hottest topic in test. During this period, automated test equipment (ATE) has made a dramatic move towards low-cost design for test (DFT) ...

The ability to control test cost while design sizes have grown exponentially is a success story that relies on the invention and continuous improvement of embedded test compression. One way test ...

Compression tests are used to characterize various compressive properties such as the compression modulus and compressive strength. They are performed on fiber-reinforced composites with ...
