High-Speed Serial Trace Probe

Higher bandwidth trace using fewer SoC pins

To enable the capture of multiple lanes of high-speed serial trace, Arm has created the HSSTP trace probe. Replacing the parallel trace port that ships with DSTREAM, HSSTP trace probe is ideal for situations where it's necessary to collect a large amount of trace data and/or where SoC termination count rules out parallel trace.

  • Supports Arm HSSTP and Marvell® SETM protocols
  • Up to 12.5 Gbps single-lane line rate
  • Debug and trace connectivity
  • Uses 4 Gigabyte trace buffer in DSTREAM

Rapid Trace

Up to 20 Gbps combined lane rate to capture detailed trace information from CoreSight and custom IP devices.

Fewer Trace Pins

The cost of supporting parallel trace can be significant. Serial trace requires fewer pins on your SoC.

Trace Configuration and Analysis

Development Studio offers advanced configuration options for collecting and analyzing trace data. These enable you to focus only on the critical sections of a program:

  • Use tracepoints to start and stop trace at specific points in your code
  • Filters allow you to select only the trace data types that you're interested in to display in the Development Studio Trace view
  • Both of these features help you to avoid filling the trace buffer rapidly when collecting High Speed Serial Trace

The Trace view also allows you to search for timestamps, functions and instructions by addresses, helping you to sift through trace data quickly and efficiently.
