Novel approach to reduce power droop during scan-based logic BIST

, 2013
Significant peak power (PP), thus power droop (PD), during test is a serious concern for modern, complex ICs. In fact, the PD originated during the application of test vectors may produce a delay effect on the circuit under test signal transitions.

Scan Latch Partitioning into Multiple Scan Chains for Power Minimization in Full Scan Sequential Circuits

, 2000
Power dissipated during test application is substantially higher than power dissipated during functional operation which can decrease the reliability and lead to yield loss.

Ultrasonic C-Scan Standardization for Polymer-Matrix Composites - Acoustic Considerations [PDF]

, 1998
Ultrasonic C-scan inspection techniques are widely used for the non-destructive evaluation of fiber-reinforced polymer composites. A C-scan is any two-dimensional scan of a specimen that produces a map of a parameter, such as reflected amplitude, as it ...
