Using the Emulation Analyzer
To display the trace status
the message "Arm not received" or "Arm received" is displayed. The display
indicates if the arm condition happened any time since the most recent trace
started, even if it happened after the trace was halted or became complete.
(The "Making Coordinated Measurements" chapter explains arm conditions.)
The "Arm to trigger" line displays the amount of time between the arm
condition and the trigger. The time displayed will be from -0.04
microseconds to 41.943 milliseconds, less than -0.04 microseconds, or greater
than 41.943 milliseconds. If the arm signal is ignored or the trigger is not in
memory, a question mark (?) is displayed.
The "States" line shows the number of states that have been stored (out of
the number that is possible to store) and the line numbers that the stored
states occupy. (The trigger state is always stored on line 0.)
The "Sequence term" line of the trace status display shows the number of the
term the sequencer was in when the trace completed. Because a branch out
of the last sequence term constitutes the trigger, the number displayed is
what would be the next term (2 in the preceding example) even though that
term is not defined. If the trace is halted, the sequence term number just
before the halt is displayed; otherwise, the current sequence term number is
displayed. If the current sequence term is changing too quickly to be read, a
question mark (?) is displayed.
The "Occurrence left" line of the trace status display shows the number of
occurrences remaining before the primary branch can be taken out of the
current sequence term. If the occurrence left is changing too quickly to be
read, a question mark (?) is displayed.
