NpiStatusInfo |
Structure Pointer with NPI Status details
- NpiStatusInfo->Status: Provides details about NPI scan
- Bit [31]: 0 - No error, SHA-3 engine is present 1 -
Cryptographic acceleration blocks are disabled for export
compliance. No support for NPI scan, an event will be sent to R5
- Bit [30]: 0 - NPI scan is running for scheduled interval 1 -
Indicates NPI scan failed to run on scheduled interval. If NPI
scan is not executed as per the configured periodicity, R5 user
is notified of the error. The scan continues to run.
- Bit [29]: 0- No descriptor missed during scanning 1- Indicates
NPI scan failed to scan all descriptors completely (excluding
arbitration failures). R5 user is notified of the error. The
scan continues to run.
- Bit [28]: 0 - NPI scan executing within budget time 1 -
Indicates NPI scan has exceeded maximum budget execution time of
20ms. R5 user is notified of the error. The scan continues to
run.

- Bit [27]: 0 - No error in SLR to SLR communication 1 - Indicates
failure in SSI technology internal communication channel. This bit is
applicable for SSI technology devices.
- Bit [26]: Reserved
- Bit [25]: 0 - No error in PMC_PL_GPO 1 - Indicates GPO
Initialization or write failed. This is HW failure. In this condition,
the scan will be stopped, and notification will be sent to R5
- Bit [24]: 0 - No error SHA-3 engine 1 - Indicates SHA engine failed
to function during initialization or start or DMA transfer. This is HW
failure. In this condition, the scan stops and R5 is notified.
- Bit [23]: 0 - No error in register writes 1 - Indicates the register
write and read back failure occurred during the scan. This is HW
failure. In this condition, the scan stops and R5 is notified.
- Bit [22]: Reserved
- Bit [21]: 0 - No error in DDR calibration 1 - Indicates NPI DDRMC
Main Slave Arbitration Timeout occurred during the scan. If the DDRMC
calibration is not done, the descriptor skips and scan continues to
run for next descriptor
- Bit [20]: 0 - No error in descriptor format 1 - Indicates NPI
Descriptor has invalid format. This failure indicates that there is
some corruption in the XilSEM NPI descriptor data. The scan stops and
a notification is triggered to R5.
- Bit [19]: 0 - No error in NPI Descriptor SHA header 1 - Indicates
NPI Descriptor SHA Header mismatch occurred during the scan. This
failure indicates that there is some corruption in the XilSEM NPI
descriptor data. The scan stops and a notification is triggered to R5.
- Bit [18]: 0 - NPI descriptors are present in the memory 1 -
Indicates the absence of NPI Descriptor (Zero descriptors) This
failure indicates that there is some corruption in the XilSEM NPI
descriptor data. The scan stops and a notification is triggered to R5.
- Bit [17]: 0 - No error in SHA comparison during run time 1-
Indicates SHA comparison failure occurred during run time. This
failure indicates that there is some bit flip in the NPI registers.
The scan stops and a notification is triggered to R5.
- Bit [16]: 0 - No error in SHA comparison during first scan 1-
Indicates SHA comparison failure occurred during initialization. This
failure indicates that there is some bit flip in the NPI registers.
The scan stops and a notification is triggered to R5.

- Bit [15-12]: NPI Target SLR ID 0001 - Target is master only 0010 -
Target is slave 0 only 0100 - Target is slave 1 only 1000 - Target is
slave 2 only
- Bit [11]: 0 - NPI scan task is not added to PLM Scheduler to run
periodically 1 - NPI scan task is added to PLM Scheduler to run
periodically This bit is for NPI scan state information.
- Bit [10]: NPI scan is suspended 0 - NPI scan is not suspended 1 -
NPI scan is suspended due to errors This bit is for NPI scan state
information.
- Bit [09]: 0 - NPI scan initialization is not done 1 - NPI scan
initialization is done This bit is for NPI scan state information.
- Bit [08]: 0 - NPI scan is present in the design 1 - NPI scan
disabled in the design This bit is for NPI scan state information.
- Bit [07-06]: Reserved
- Bit [05]: 0 - No internal error 1 - NPI scan is in error state (due
to timeouts, invalid descriptors) This bit is for NPI scan state
information.
- Bit [04]: 0 - No error in NPI Scan 1 - NPI scan in SHA comparison
mismatch error state. This bit is for NPI scan state information.
- Bit [03]: 0 - NPI scan is not in SHA error inject state 1 - NPI scan
is in SHA error inject state. This bit is for NPI scan state
information.
- Bit [02]: 0 - NPI scan is not in scan state 1 - NPI scan is in scan
state. This bit is for NPI scan state information.
- Bit [01]: 0 - NPI scan is not in initialization state 1 - NPI scan
is in initialization state This bit is for NPI scan state information.
- Bit [00]: 0 - NPI scan is not in idle state 1 - NPI scan is in idle
state This bit is for NPI scan state information.

- NpiStatusInfo->SlvSkipCnt: Provides NPI descriptor slave skip
counter value if arbitration failure. This is 8 words result to
accommodate 32 1-Byte skip counters for individual slaves arbitration
failures. Slaves can be DDRMC Main, GT for which arbitration is
required before performing scanning.
- NpiStatusInfo->ScanCnt: NPI scan counter value. This counter
represents number of periodic scan cycle completion.
- NpiStatusInfo->HbCnt: NPI heartbeat counter value. This counter
represents number of scanned descriptor slaves.
- NpiStatusInfo->ErrInfo: NPI scan error information if SHA
mismatch is detected. This is 2 word information.
- Word 0: Node ID of descriptor for which SHA mismatch is
detected
- Word 1 Bit [15-8]: NPI descriptor index number
- Word 1 Bit [7-0]: NPI Slave Skip count Index
