Event Description
This event is set when the analyzer does not receive ALIGN(1)
primitives from one or both ends of a SAS link at 3.0 Gbps rate
during Final-SNW window of the SAS speed negotiation sequence.
This event marks the beginning of the Train-SNW speed negotiation
window at 3.0 Gbps rate with SSC (Spread Spectrum clocking)
enabled.
This event marks the end of the Train-SNW speed negotiation
window at 3.0 Gbps rate with SSC enabled.
This event is set if a SAS-3 phy has transmitted at least 4
TRAIN_DONE patterns and received at least 1 TRAIN_DONE
primitive at 3.0 Gbps rate within MTT (Maximum Training time ~ 20
ms), during a Train-SNW speed negotiation window with SSC
enabled.
This event is set if a phy has not transmitted at least 4 TRAIN_DONE
patterns or not received 1 TRAIN_DONE at 3.0 Gbps rate within MTT
(Maximum Training time ~ 20 ms), during Train-SNW speed
negotiation window with SSC enabled.
This event marks the beginning of the Train-SNW speed negotiation
window at 3.0 Gbps rate with SSC (Spread Spectrum clocking)
disabled.
This event marks the end of the Train-SNW speed negotiation
window at 3.0 Gbps rate with SSC disabled.
This event is set if a SAS-3 phy has transmitted at least 4
TRAIN_DONE patterns and received at least 1 TRAIN_DONE
primitive at 3.0 Gbps rate within MTT (Maximum Training time ~ 20
ms), during a Train-SNW speed negotiation window with SSC
disabled.
This event is set if a phy has not transmitted at least 4 TRAIN_DONE
patterns or not received 1 TRAIN_DONE at 3.0 Gbps rate within MTT
(Maximum Training time ~ 20 ms), during Train-SNW speed
negotiation window with SSC disabled.
This event marks the beginning of the Train-SNW speed negotiation
window at 6.0 Gbps rate with SSC (Spread Spectrum clocking)
enabled.
This event marks the end of the Train-SNW speed negotiation
window at 6.0 Gbps rate with SSC enabled.
This event is set if a SAS-3 phy has transmitted at least 4
TRAIN_DONE patterns and received at least 1 TRAIN_DONE
primitive at 6.0 Gbps rate within MTT (Maximum Training time ~ 20
ms), during a Train-SNW speed negotiation window with SSC
enabled.
This event is set if a phy has not transmitted at least 4 TRAIN_DONE
patterns or not received 1 TRAIN_DONE at 6.0 Gbps rate within MTT
(Maximum Training time ~ 20 ms), during Train-SNW speed
negotiation window with SSC enabled.
