It contains the following additional control:
View
This control van be used to select the Analyzer nodes to view information for. By clicking on the "a", "b" or
"c", the corresponding nodes can be hidden or shown. A red background indicates a node is shown. A
white background indicates a node is hidden.
7.2.2.2. Packet / event display
The packets and events are displayed below the toolbar. Packets (including acknowledge packets) are
drawn as colored rectangles on a black 'base-line'. The color of the rectangle indicates the type of packet.
The used packet colors are:
cycle start packets
stream packets
read/write/lock request packets
read/write/lock response packets
phy packets
packets with error(s)
acknowledge packets
Before each packet, a light gray rectangle is drawn, indicating the packet prefix. In case of a hidden
packet, only this prefix is drawn, which has a duration of the complete packet.
The height of the packet rectangles indicates the packet speed. There are 4 different heights (from lowest
to highest):
1. for the 100 Mb/s packets and packet prefix
2. for the 200 Mb/s speed packets
3. for the 400 Mb/s speed packets
4. for the 800 Mb/s speed packets (FireSpy800 only)
Below you see an example with a request and cycle-start packet at 100Mb/s speed, followed by a (big)
stream packet at 800 Mb/s speed, followed by a response packet at 200Mb/s and after that a few (small)
request packets at 400 Mb/s speed.
The cursor is a vertical line with little triangles on the top and bottom, as shown above (left to the first
packet).
Events are drawn as vertical lines from the base line to the top, with a letter to the right of the line
(somewhere at the top). The letter indicates the event type as follow:
T = Trigger
R = Bus Reset
S = Subaction Gap
A = Arbitration-Reset Gap or EventA (EventA has a darker Line)
B = EventB
C = EventC
C = Cycle Start (FireSpy800 only)
I = Phy Interrupt
The Trigger event will be displayed at the position where the trigger occurred. The position will correspond
to the absolute time 0 (zero).
The Bus Reset event will be displayed at the position where the link interface signals a bus-reset status.
Bus resets are always stored during the recording.
Both the Subaction Gap and Arbitration-Reset Gap events are displayed at the position where the link
interface signals the corresponding status. By default these events are not stored when recording, but the
