Abstract

The effect of test compaction on fault diagnosis isexperimentally investigated. Results for combinational andsequential circuits indicate that the diagnostic resolutionachieved by compacted tests is only minimally lower thanthat for uncompacted tests. Furthermore, the diagnosticresolution of the compacted tests can be enhanced to bethe same or better than that for the uncompacted testswhile still retaining compactness.
