of the view (see below).
requester - responder
These columns display the source ID and destination ID respectively of the request packet for this
transaction. Response transaction will have a source ID equal to the responder column and destination ID
equal to the requester ID.
The format of these values follows the same rule as the source and destination columns in the list of the
Packet View.
data offset
This column will hold the data offset of the associated data transfer. It equals the data-offset field of the
request packet.
data length
This column will hold the data length of the associated data transfer.
label
The last column has the value of the label field for both the request and response packets.
Triple Analyzer
The transactions table columns to show are selectable through the transaction column menu. This menu
is displayed after the table header is clicked with the right mouse button. The displayed menu is shown in
the figure below.
7.5.2.3. Transactions Details
Right to the transaction table, the details of the selected transaction can be seen if the ‘Toggle transaction
details on/off button’ is pressed (on).
The transaction details box has 4 to 6 pages (depending of the presence of errors and or warnings):
Packets
Selecting this page will show the page with a list of all the packets that make up the transaction. In the
example above, the selected transaction consists of a read request packet, followed by a read response
packet.
In this packets page you also can see the retry-code and response-code (if present) of the packets and (if
the packet was followed by an acknowledge packet) the acknowledge code sent.
If you select a packet in this list, it will also be selected in the other views. So you can select it and
investigate the packet details in the Packet View or check its position on the time line in the Time View.
If you want to know the time between request transmission start and response transmission start for
instance, simply select the request, switch the Time View to relative cursor mode, and click the response
packet. The Time View will display the difference in transmission start time in its 'Cursor Time' box.
You can use the left- and right- arrow keys to step through the list of transaction packets.
