6.1.7. About the Observation Network
The observation network connects probes to the observer, which is a port in the CoreSight* trace funnel. Through the observation network, you can perform these tasks:
- Enable error logging
- Selectively trace transactions in the system interconnect
- Collect HPS transaction statistics and profiling data
The observation network consists of probes in key locations in the interconnect, plus connections to observers. The observation network works across multiple clock domains, and implements its own clock crossing and pipelining where needed.
The observation network sends probe data to the CoreSight subsystem through the AMBA* Trace Bus (ATB) interface. Software can enable probes and retrieve probe data through the interconnect observation registers.
