Note
8-22 Timing: Using the Analyzer
You can search for a specific signal pattern with a command like
find entering X_lower =01010111
that looks for specific combination of true an false signals on probe
bits "0" through "7", or for a transition specific signal with a
command like
find entering X_lower .2 = 1
which attempts to find where bit 2 of X_lower (probe signal "2")
becomes true. In both cases, the search begins at the cursor and, if
the pattern is found, the sample is positioned in the middle of the
display. The "entering" syntax denotes that a signal or signals are
changing to the indicated logical value for the pattern specified.
The trigger command does not have a corresponding "entering"
function. It simply matches the pattern specified.
The command
find entering X_lower .2 = 1 all
is has the same effect as the last search, but starts from the
beginning of trace memory instead of at the cursor.
You can also look for any change on a signal. The command
find any_transition on X_lower .2 = 1 thru
end <RETURN>
searches for any change on bit 2 of X_lower from the cursor to the
end of trace memory. Other options can terminate the search:
trigger, mark_x, mark_o, a specific sample number, the start of
trace memory, as well as the end of the trace. If the specified "thru"
location is before the cursor, the search starts at that location and
ends at the cursor.
