Active Marker
Any action that uses a marker will automatically designate that marker as the "Active Marker".
The active marker exposes additional properties and associated items for easier navigation
and support to 'bring the data to center' concept.
Waveform Association
Snap Left/Right
Marker Tack
When you snap a marker to a waveform, it becomes associated with that waveform as
indicated by the reversed color in the Active Marker Column on the right. In the image
below, Marker A is associated with ASYNCTX and the value of ASYNCTX at the marker
position is 0x45 as shown in the Active Marker Column.
To associate the Active Marker to another waveform and snap to the next edge of the
waveform, right or left click in the Active Marker Column of the waveform.
To snap the active marker to the previous or next edge of the associated waveform, either
right or left click in the Active Marker Column or on the dedicated snap button next to the
Active Marker Column's marker identifier. In the image above the identifier is "A" and the
dedicated button is the same color as marker A.
This allows one to walk any marker from edge to edge on a specific signal. To walk
through two different sections of data or two different signals, simply select each desired
marker using the Quick Select flags. Each marker maintains its position, allowing one to
jump back and forth between them. You can walk one signal for a while, jump to the other
marker and walk that signal and then jump back to the first marker and pick up where you
left off.
Left-Click to Snap Left.
Right-Click to Snap right.
The button just above the Active Marker's snap button will toggle the "Tack" feature of the
marker. When the button is pressed tacking is enabled. When the Tack option is active,
snapping the marker will bring the data to the center of the screen instead of moving the
marker out of view.
You can still drag the marker (with or without auto-snap) to another point in the data, but
when you release the mouse button, the marker AND the data will be brought to the center
of the screen, ready for zooming in/out.
TACKing a marker is particularly useful for walking though a signal, edge by edge.
Normally, when you SNAP the a marker, the marker moves to the previous or next edge of
the associated signal. When the marker is tacked, the DATA is brought to the MARKER
