Infineon TriCore: Synchronization between On-Chip trace and external sources (ADIO, CAN/LIN)

On-Chip trace logic monitors the CPU execution inside the SoC.

Obtained data is compressed using trace protocols and:

• Streamed out through the trace port, where BlueBox debugger is capturing the data on the trace port. Each sample is time stamped by the BlueBox timer OR
• Captured in the internal trace RAM (On-Chip trace buffer - OCTB), where trace data is uploaded through the debug port after it was time stamped by the On-Chip timer.

To synchronize events all recorded samples should use the same (or synchronized) timer:

• If a BlueBox timer is used with all the samples, events are synchronized by design;
• If  an On-Chip timer is used in combination with ADIO, CAN/LIN, synchronization is required.

Possible solution: 

To synchronize events from different time domains (BlueBox and On-Chip timer) check Generate time synchronization messages option (if supported) in View / Analyzer / Analyzer Configuration.
