Chapter 4, Xgig TraceControl Capture Configuration Capture and Trigger Setup

Ignore errors during Low Power States (Also affects LEDs, Counters, and State
Transitions)
When checked, the hardware excludes the errors produced when a DUT goes in and out of a low
power state (ASPM mode) from the capture. It will also ignore them for state transition condition,
LEDs and error counter columns. The same option can be found on the Lane Control Tab. The
setting is set by default.
Ignore errors during SATA Scrambled Primitive Data for Capture and Transition
This option is for SAS/SATA traffic. It specifies that errors that occur during SATA Scrambled
Primitive Data are ignored. All errors on Dwords that follow the SATA Primitives, to avoid
incoming Disparity Error issues are ignored.
All capture settings that refer to errors will ignore these Dwords as if they were normal scrambled
data. Dwords will be captured without displaying errors in the trace. Errors will not be counted nor
will they cause a state transition if they are used as transition criteria.
Limit the Force Capture of errors to lane-bound traffic only
This option is for PCIe traffic. It reduces the capture of random errors. This option is checked by
default.
Out-Of-Band (OOB) and Speed Negotiation Options
The options in this section specify what OOB and speed negotiation data TraceControl should
capture. The default is to capture all events. Possible options are:
•
Capture all OOB & Speed Negotiation events
All OOB and speed negotiation data is captured, as well as all other events. This is useful
when looking for timing-related problems. This is the default value.
• Capture only OOB & Speed Negotiation events
Primarily only OOB and speed negotiation pseudo events are captured. In addition, this option
captures TX training frames when there is a change in the content of the training frame when
compared to the previous training frame. No training patterns i.e. TRAIN, TRAIN_DONE or
random training data will be captured.
•
Do not capture OOB & Speed Negotiation events
All OOB and speed negotiation events and data are ignored.
When using two-state, three state, or multi-state (Advanced) triggering for 6G SAS/SATA and
12G SAS, these options can be selected for different states.
Force the capture of Gen3 Bad STP Errors Forces capture of all Gen3 bad STP errors.
Force the capture of Gen3 Invalid STP TLP Length Errors Forces capture of all Gen3 invalid STP TLP length errors.
Force the capture of EDB Errors Forces capture of all EDB errors.
