ITM, DWT, ETM
Output via
4 trace data pins
+ 1 clock pin
Trace (ETM, ITM, DWT) not available on Cortex-M0
Code Coverage (ETM)
 Complete software validation requires code coverage
 Product liability and industry standards (IEC61508) demand for testing
according to “State of Science and Technology” methodologies
 ETM enabled devices provide complete instruction stream
 Non-intrusive - use final, optimized code at full speed
 Feedback provided directly in the debugger window
 Source & disassembly view
 Color-coded details for
individual instructions
 Summary analysis by
function or module
 Log File Support
 Coverage information can
be saved for documentation
Instruction Trace (ETM)
 Execution history of all executed instructions
 Instruction Trace window displays: cycle count (timing) and assembly
code synchronized to the C source code.
 Instruction Trace is useful to analyze sporadic problems
 Data corruption by incorrect interrupt/thread protection
 Incorrect timing caused by interrupt/thread nesting
What is Streaming Trace?
 Trace data transferred in




real-time to debug host
Capture size only limited by host
resources (harddisk)
Trace for minutes, hours, or longer
Required for full code-coverage
and timing analysis
Today’s workstations can present
trace data instantly
