5.2 Viewing Trace Files
In addition to the Display Options, there are a number of commands and tools available for
further customizing and interpreting the display of an active traffic recording (.fdb) Trace
file. Although traffic generation (.txg) Traces contain many of the same elements, they are
limited to a packet-level view and aren’t exactly the same. To find out more about traffic
generation files, please refer to Chapter 7, “Traffic Generation,” on page 91.
5.2.1 Packet-Level Decoding
Packet-level decoding is a low-level interpretation of the data on the 1394 bus. FireInspector
takes the data and separates it into the fields displayed in the Trace. Individual packets are
shown on separate rows.
These types of packets are displayed at the packet level: asynchronous (read data, write data,
lock, GASP, and cycle start), isochronous, and PHY (self-ID, configuration, link-on,
extended).
By default, FireInspector displays all transactions at the packet level, unless the Display
Options settings have been configured to do otherwise. Almost all packet fonts, visibility,
and field colors can be configured in the Display Options.
General Packet Display Elements
The following can be found in the Trace display for any kind of packet:
• Packet number fields (Packet) — All packets in a Trace are numbered, starting at 0, in
the order that they were recorded. The packet number field is always first in a row of
packet fields.
• Packet header and data block — By left-clicking* on the packet number field and select-
ing View Fields from the cell context menu that pops up, you can look at the contents of
the packet header and data block. The data is presented according to the 1394 specifica-
tion. See “View Fields” on page 75 for more details.
*If the option Right click cell context menu is checked on the General tab of the Display Options dialog,
then the cell context menu is opened by right-clicking. See Section 5.1.1, “General Display Options” on
page 42 for more information.
• Raw quadlets — By left-clicking* on the packet number field and selecting View Raw
Quadlets from the pop-up menu, you can view the raw numbers for the packet data. See
“View Raw Quadlets” on page 75 for details.
*If the option Right click cell context menu is checked on the General tab of the Display Options dialog,
then the cell context menu is opened by right-clicking. See Section 5.1.1, “General Display Options” on
page 42 for more information.
