Protocol Errors
Teledyne LeCroy
STP Invalid State Transition (Unexpected Primitive) [SAS only] or FIS Invalid State
Transition (Unexpected Primitive) [SATA only]: Second SATA_SOF is encountered before
SATA_EOF, and other unexpected primitives.
STP Invalid State Transition (Primitive Timeout) [SAS only] or FIS Invalid State Transition
(Primitive Timeout) [SATA only]: Timeout between two paired primitives is above entered
value. 65000 DWORDs is default. For example, it can occur between WTRM and R_OK, or
X_RDY and R_RDY. It expects device (or host) to send a response, but response is not
received after 65000 DWORDs. You can configure Primitive Response Timeout and HOLD/
HOLDA Response Timeout in the Settings tab Analyzer Settings section.
Frame Type Error: Wrong frame type.
Frame Length Error: Reported frame length is different than actual frame length.
Frame Direction Error: Wrong frame direction. For example, Register Device to Host
coming from the Host.
CRC Error: CRC error detected.
ACK/NAK Timeout [SAS only]: ACK or NAK primitive missing or encountered
unexpectedly.
Delimiter Error: Detects two SOF primitives without an EOF between them. Also detects
two EOF primitives without an SOF between them.
Radio Buttons: All, SSP, SMP and STP ‐ By selecting one of these radio boxes you can
specify that you want to trigger(or filter) on a specific protocol error on a specified frame
type. If you check CRC error and select the SSP radio button, if a CRC error occurs on a
SMP frame, the analyzer does not trigger on it.
Hashed Destination SAS Address (SSP trigger only): Specify the destination address for
the analyzer to locate specific protocol errors.
Hashed Source SAS Address (SSP trigger only): Specify the source address for the
analyzer to locate specific protocol errors.
