1999 17TH IEEE VLSI Test Symposium
REDO - Probabilistic Excitation and Deterministic Observation - First Commercial Experiment
San Diego, California
April 26-April 30
ISBN: 0-7695-0146-X
For many years, non-target detection experiments have been simulated by using AND/OR bridges or gross delay faults as surrogates. For example, the defective part level can be estimated based upon surrogate detection when test patterns target stuck-at faults in the circuit. For the first time, test pattern generation techniques that attempt to maximize non-target defect detection have been used to test a real, 100% scanned, commercial chip consisting of 75K logic gates. In this experiment, the defective part level for REDO-based patterns was 1,288 parts per million lower than that achieved by DC stuck-at based patterns generated using today's state of the art tools and techniques.
