Abstract :
Stochastic coding is used to design X-tolerant signature analyzers that can detect defective chips even in the presence of unknown logic values (X´s). These signature analyzers can be used for built-in-self-test applications and test data compression. Application of this technique to industrial designs shows that thousands of X´s can be tolerated while reducing test response data volume by 50 to 2,000 times compared to traditional scan, with practically no impact on test quality.
