Chapter 7: Using the Emulation Analyzer
The Basics of Starting, Stopping, and Displaying Traces
To change the trace depth
• Using the command line, enter the display trace depth command.
The display trace depth command allows you to specify the number of states that
are displayed. By reducing the trace depth, you can shorten the time it takes for the
interface to upload the trace information. You can increase the trace depth to view
more states of the current trace.
The maximum number of trace states is 1024 when counting is turned off, 512
otherwise. The minimum trace depth is 9.
If you wish to reduce the number of states that are displayed, the display trace
depth command must be entered before the trace command. You cannot use this
command to reduce the number of states displayed in the current trace.
To modify the last trace command entered
• Choose Trace→Trace Spec and use the dialog box to select and edit a trace
command.
• Using the command line, enter the trace modify_command command.
The Trace Specification Selection dialog box contains a list of trace specifications
executed during the emulation session as well as any predefined trace specifications
present at interface startup.
You can predefine trace specifications and set the maximum number of entries for
the dialog box by setting X resources (see the "Setting X Resources" chapter).
The trace modify_command command recalls the last trace command. The
advantage of this command over command recall is that you do not have to move
forward and backward over other commands to find the last trace command; also,
the last trace command is always available, no matter how many commands have
since been entered.
