In the default state, all of the diagnosis results are reflected in the final results of the verification.
Even if set with “VF target select” so as not to reflect the diagnosis results to the final results of
the verification, execution time for the verification does not change because the diagnosis itself is
executed. In addition, the diagnosis results selected to “0” with Verification Target are displayed
as “Skip”.
Note that verification itself cannot be executed if all diagnoses are unchecked in the check box of
Verification Target (0x0000).
The diagnosis result is displayed as shown below.
