Abstract
The present invention provides various circuits for injecting faults into a larger circuit, sometimes called circuit under test, or CUT. One type of fault injection circuit is a clock controlled fault injection circuit. This type of circuit uses internal scan chains as a way by which a fault injection operation is performed while a system clock is in the off state. Another type of fault injection circuit is a concurrent fault injection circuit. This type of fault injection circuit uses dedicated fault injection scan chains in parallel with or without internal scan chains. Yet another type of fault injection circuit is a hybrid fault injection circuit that uses both clock controlled and concurrent fault injection circuits. Other embodiments are disclosed and still other embodiments would be obvious to those of ordinary skill in the art upon understanding the full scope of the present disclosure.
