Abstract

In previous work, we have shown that optimizing the number ofsite observations leads to more defect detection. However, forincreasingly difficult defects, optimizing patterns for balancedrandom excitation also enhances test effectiveness. We can alsoreduce the effect of undetected defects by choosing tests thatminimize the likelihood of field failures.
