more topology changes.
The recorder will search for recorded bus transactions that will give more information about the
Configuration ROM and Bus_Manager_ID register. It searches for read transactions of the Configuration
ROM and for lock transactions on the Bus_Manager_ID register. It will search, starting with the last reset
event before the current cursor position until the next reset event or until the end of recorded packets. If
no reset was recorded before the cursor position, it will search from the beginning of the recorded packets.
If some information cannot be found because the corresponding transactions could not be found, the
corresponding information will not be displayed or a ‘?’ will be displayed in place of the information. All
information that can be found, will be displayed (if requested by the user).
Note that if a correct lock transaction on the Bus_Manager_ID register is found, but it indicates that no
Bus Manager is present, the value ‘(none)’ will be displayed. If no correct lock transaction could be found,
the Bus Manager line isn’t displayed at all.
Vendor names lookup
The Vendor ID is a 24-bit value. It will be displayed, if requested, inside the node rectangle or in the extra
information at the right of the topology picture.
Because a 24-bit ID is difficult to recognize, the Analyzer software will try to look up the vendor name
corresponding to this 24-bit ID in an external file. If found, this name will be used inside the node
rectangle (in place of the 240-bit value) and will be added to the vendor-ID value in the extra information
list. The file used for this is placed in the ...\bin folder. It has the name oui.txt. Updates of this file can be
found at the IEEE organization website at:
http://standards.ieee.org/regauth/oui/index.shtml Here you can
find free public updates of this file.
If this file is not present, only the 24-bit Vendor-ID value will be displayed.
7.4. Packet View
The Packets View is one of the possible views in the Recorder which you can use to investigate the
recorded packets and events. It displays all packets and events sequentially in a table. Optionally,
additional information of a selected packet can be displayed, including the packet fields and their values,
the packet layout and possible warnings and errors that are detected for the packet.
7.4.1. How to use it
You can display/remove the Packets View by checking/unchecking the Packets View item in the 'View'
menu of the Recorder. There is also a shortcut key to toggle the state. An example of the Packets View is
dispayed below:
At the top of the view you see a toolbar with some buttons that enables quick selection of some event and
packet types. Below the toolbar you see the packets/events table on the left and optionally the packet
