Trace Protocol

The UltraSoC Trace Encoder generates instruction execution details based on an UltraSoC proprietary trace protocol. The protocol includes an optional timestamp field. These timestamps are the only way to get time information for the onchip or the USB trace. If the trace is recorded with a TRACE32 Trace Module, the timestamps are generated by the module.

Pure UltraSoC Trace Infrastructure

The UltraSoC trace infrastructure IP can be integrated into any RISC-V based chip.

Generic Trace Features

Trace-based Debugging (CTS)
  • Allows re-debuggging of a traced program section
  • Provides forward and backward debugging capabilities
  • High-level language trace display including all local variables
  • Timing and function nesting display
  • Has the ability to fill most trace gaps caused by the limited bandwidth of trace port

Trace-based Profiling
  • Detailed analysis of function run-times
  • Detailed analysis of task run-times and state
  • Graphical analysis of variable values over the time
  • Analysis of the time interval of a single event (e.g. Interrupt)
  • Analysis of the time interval between 2 defined events

Trace-based Code Coverage
  • Provides all metrics for functional safety
  • For standard trace protocols TRACE32 Code Coverage gets by with no or very little instrumentation, full instrumentation as fallback
  • Suitable for long-term testing
  • Automated report generation in multiple exchange formats
  • TRACE32 Trace-Based Code Coverage is included in the scope of delivery of all TRACE32 Debug & Trace Tools at no additional cost
