Highlights

	Based on Nexus message protocol (small, medium or full)
	Program, data and register trace
	Trace protocol may include timestamps or cycle count
	Multicore tracing
	Trace filter allow to reduce the generation of trace messages
	ARC-only trace or integrated into an Arm CoreSight trace infrastructure
	Onchip trace, parallel Nexus trace port, CoreSight TPIU, Arm HSSTP
	Support for ARC-EM11D, ARC-EM4, ARC-EM5D, ARC-EM6, ARC-EM7D, ARC-EM9D, ARC-HS34, ARC-HS36, ARC-HS38, ARC-HS44, ARC-HS45D, ARC-HS46, ARC-HS47D, ARC-HS48

Nexus 5001 Compliant Trace Protocol

Three expansion stages are possible for the trace logic.

Small: Instruction trace only
Medium: Instruction and data trace
Full (rarely implemented): Instruction, data and register trace (read and write to auxiliary registers and write only to core registers)

The execution of conditional non-branch-instructions is also output thanks to branch-history.

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
