Fault coverage
open-in-new
<p>Fault coverage refers to the percentage of some type of <a href="/facts/Fault_(technology)/jeQPed50">fault</a> that can be detected during the test of any engineered system. High fault coverage is particularly valuable during manufacturing test, and techniques such as <a href="/facts/Design_For_Test/wGKySXgc">Design For Test</a> (DFT) and <a href="/facts/Automatic_test_pattern_generation/NGPXXf1o">automatic test pattern generation</a> are used to increase it. </p>
