Abstract

The study of faulty signature (checksum) in computer hardware testing is presented. When a faulty signature is observed, it is caused by one of many possible input sequences that contain errors at different locations. The faulty signature is analyzed in order to reduce the number of tests and simplify the fault-isolation process. It is found that the number of errors among the sequences is distributed with binomial characteristics. To support the analysis, a computer simulation is performed to analyze the distributions of undetected errors.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
