finds a matching frame, the marker moves to the frame. If necessary, the system

scrolls the bus analyzer window to make the frame visible. If the search does not find a

matching frame, an error message reports that fact.

4.10.5.2.5 Previous Event

To search for the previous occurrence of the specified event, choose the

Trace>Search >Previous Event menu selection. The analyzer searches backwards

from the selected frame to find the previous frame that matches your event

specification. (Pressing the keyboard P key, without activating the Trace menu, is

another way to activate this search.) If this search finds a matching frame, the marker

moves to the frame. If necessary, the system scrolls the bus analyzer window, to make

the frame visible. If the search does not find a matching frame, an error message

reports that fact.

4.10.5.3 Search for a Pattern

To search for a frame that matches a pattern, you must define the search pattern (an

address, a data word, logic clips, and four miscellaneous signals). To do so, choose the

Trace>Search>Pattern... menu selection. This opens the Pattern page of the Bus

Analyzer Configuration dialog box as shown in Figure 4.29:
