The Simulation Message Summary dialog box lists message
header information. You can filter the messages displayed in the
list by selecting a severity level from the Minimum Severity
Level drop-down menu. Messages are categorized (in
decreasing order of severity) as FATAL, SERIOUS,
WARNING, or INFO (informational).
When you select a severity level, the Message Summary
displays only those messages with the chosen severity or higher.
By default, the minimum severity level displayed is SERIOUS.

In the Simulation Message Summary dialog box, double-

For most message conditions, a Probe window appears that
contains the waveforms associated with the simulation
condition, along with detailed message text.
How Probe handles persistent hazards
If a PERSISTENT HAZARD message occurs, two plots display
(see Figure 17-12) containing the following:
• the waveforms initially causing the timing violation or
hazard (lower plot)
• the primary outputs or internal state devices to which the
condition has propagated (upper plot)
Example: If you select

severity level, the Simulation
