If any of those checks detect a problem, the simulation is reported as failing. In a
correctly operating testbench, the only reason for failing is the detection of
deliberately inserted errors. There is a distinction between a simulation run failing
and a test failing. If you insert errors and the errors are detected, the simulation fails.
However, the test was successful because the errors were detected. For this reason,
simulation failure is not by itself an indication of a problem.
Example 5–1 shows the
ModelSim log for a successful run.
