When random Dwords are captured
This option is for 6G SAS/SAT,12G SAS, and PCIe traffic. It specifies how to process random
Dwords when random Dwords are captured. The default is to compress random Dwords to a
count.
•
Store each individual Dword
All random Dwords generated during OOB and speed negotiation are captured and stored
individually. Repeat Counts are not used.
• Compress to a count of Dwords
All random Dwords are compressed into Repeat Counts.
Transition Editor
The Transition Editor on the
Capture and Trigger Setup
tab is shown when you highlight a
transition. The transition editor allows you to capture the key information that you are looking for.
At a minimum, you are directing the analyzer when to stop. There are many options available for
determining where to set these stop points, including setting time-outs and counting events. You
can direct the analyzer to take certain actions based on the contents of the data it is processing.
This includes directing other analyzers to stop.
You can create transitions by using the
Available Templates Browser
to select pre-defined
elements. Drag templates from the Available Templates Browser into the Wait For Any Of
These/And NOT These
panes to specify the transition from one state to another. The
And NOT
These pane is similar to the Wait For Any Of These pane, but the templates dragged here are
inverted before they are compared. Only 6G SAS/SATA,12G SAS, and PCIe can use both of the
panes. See
“Available Templates Browser” on page 310 for more information. As you drag the
templates into the pane, the template names appear within the selected transition bubble.
The Ports Selection for Current Template sections of the panes indicate which ports are in the
current state machine. You can select or un-select individual ports to include in the configuration.
You can select any combination of ports in the
Wait For Any Of These section. However, only 6G
SAS/SATA, 12G SAS, and PCIe allow you to have both the
Wait For Any Of These
and the
And
NOT These populated for any one port.
If multiplexing is enabled for a state machine, the ports appear in the
Ports Selection for Current
Template section with a zero or a one following the port name to indicate the logical link. You can
select or deselect the checkbox for a link to choose which logical link you want to trigger on.
