Optimal scheduling of signature analysis for VLSI testing

摘要

A simple algorithm that shows how to optimally schedule the test-application and the signature-analysis phases of VLSI testing is presented. The testing process is broken into subintervals, the signature is analyzed at the end of each subinterval, and future tests are aborted if the circuit is found to be faulty, thus saving test time. The mathematical proofs associated with the algorithm are given.
