Despite their small size, analog/mixed-signal circuits start with an extensive set of parameters to test for. During production ramp up, most of these tests are dropped using statistical analysis techniques based on the dropout patterns. While effective in reducing the number of tests, this approach treats each device in an identical manner. As the statistical diversity of the devices increases due...
Adaptive testing is a generic term for a number of techniques which aim at improving the test quality and/or reducing the test application costs. In adaptive tests, the test content or pass/fail limits are not fixed as in conventional tests, but dependent on other test results of the currently or previously tested chips. Part-average testing, outlier detection, and neighborhood screening are just...
At-speed testing is becoming crucial for modern very-large-scale-integration systems, which operate at clock speeds of hundreds of megahertz. In a scan-based test methodology, it is common to use a transition delay fault model for at-speed testing. The launching of the transition can be done either in the last cycle of scan shift [launch-off-shift (LOS)], or in a functional launch cycle that follows...
