Test Generation from Finite-State Models
generate a nonnull output on the fault-detection capability of the
UIO method will be discussed in Section 3.8.8. In Figure 3.19, the set
of core edges is {(q

During a test, one wishes to determine if the IUT behaves in ac-
cordance with its specification. An IUT is said to conform strongly
to its specification if it generates the same output as its specification
for all inputs. An IUT is said to conform weakly to its specification if
it generates the same output as that generated by the corresponding
core-FSM.
Example 3.22: Consider an IUT that is to be tested against its speci-
fication M as in Figure ...
