Abstract
It is shown that for typical values of test coverage and yield, increasing the test coverage will have a greater impact on quality for a lower cost than similar increases in yield. This relationship often holds even when the increase in yield is much larger than the increase in test coverage. It must be ensured that the test coverage is based on fault models that accurately describe the behavior of fault chips, and that the simulated faults accurately represent the failures that actually occur.<>
