screen, the current trace automatically updates the display. If the trace memory
contents exceed the page size of the display, the NEXT PAGE, PREV PAGE, up
arrow, or down arrow keys may be used to display all the trace memory contents.
You also can press CTRL f and CTRL g to move the display left and right.
You can set up trigger and storage qualifications using the specify trace command.
When a cmb_execute command is given, which puts an EXECUTE signal on the
Coordinated Measurement Bus, analyzers will begin tracing.
again This option repeats the previous trace measurement. It also begins a trace
measurement with a newly loaded trace specification. (Using trace without the
again parameter will start a trace with the default specification rather than the
loaded specification.)
anything This causes the analyzer to capture any type of information.
arm_trig2
This option allows you to specify the external trigger as a trace qualifier, for
coordinating measurements between multiple HP 64700 Series emulators, or an HP
64700 Series emulator and another instrument.
Before arm_trig2 can appear as an option, you must modify the emulation
configuration interactive measurement specification. When doing this, you must
specify that either BNC or CMBT drive trig2, and that the analyzer receive trig2.
See Chapter 6, "Coordinated Measurements", for more information.
break_on_trigger
This stops target system program execution when the trigger is found. The emulator
begins execution in the emulation monitor. When using this option, the on_halt
option cannot be included in the command.
COUNT
This specifies whether time or state occurrences, or nothing, will be counted during
the trace. See the COUNT syntax diagram for details.
counting
This option specifies whether the analyzer will count time or occurrences of states
during a trace, or whether the option is to be turned off.
modify_command
This recalls the last trace command that was executed.
on_halt
When using this option, the analyzer will continue to capture states until the
emulation processor halts or until a stop_trace command is executed. When this
option is used, the break_on_trigger, repetitively, and TRIGGER options cannot
be included in the command.
only
This option allows you to qualify the states that are stored, as defined by
QUALIFIER.
