Tracking simulation messages
355
To display waveforms associated with messages
1 In the Simulation Message Summary dialog box,
double-click a message.
For most message conditions, a Probe window
appears that contains the waveforms associated with
the simulation condition, along with detailed message
text.
Persistent hazards
If a PERSISTENT HAZARD message is displayed, two
plots appear (see Figure 98), containing the following:
• the waveforms that initially caused the timing
violation or hazard (lower plot)
• the primary outputs or internal state devices to which
the condition has propagated (upper plot)
Figure 98 Waveform display for a persistent hazard.
