The NPS can detect and report a number of error conditions in the packet domain. Each error type can be enabled or disabled individually. When an error occurs, certain data is logged and an interrupt may be raised.
The NPS error conditions fall into the following categories:
- Virtual channel credit overflow and underflow
- NoC packet routing errors
- Output port parity errors
Note: While the NPS supports detection and
reporting of these error conditions, there is currently limited software support for
these features. To decode the REG_1ST_ERR_NUM register errors, see AR000035077.
