In order to help debugging and tracing, the core could embed a queue, fed by the master and the slave interfaces, to stream out some events like:
- 4 KB boundary crossing if uses AXI4 protocol
- request / completion timeout
xRESP with value equals to EXOKAY if uses AXI4-lite protocolxRESP with value equals to SLV_ERRxRESP with value equals to DEC_ERR
The debug stage must have an input to connect each interface, with a FIFO to store the events, and routing stage to stream the event for instance with an AXI4-stream interface.
The debug could be actionable per interface.
A message / event format must be specified
