Provide access to other debug components and control of debug behavior. Examples include:


Generate trace data for output through the ATB. Examples include:


Provide connection, triggering, and flow of trace data. Examples include:

  • Synchronous 1:1 ATB bridge.

  • Replicator.

  • Trace funnel.

See Chapter 6 ATB Interconnect Components.


End points for trace data on the SoC. Examples include:


Generates and transports timestamp across the SoC. Examples include:

  • Timestamp generator for generating the timestamp.

  • Timestamp encoder.

  • Timestamp decoder.
