J-Trace PRO for Cortex-M

Analyze, Verify, and Profile your Code

J-Trace PRO for Cortex-M is setting a new standard for trace probes. It enables continuous streaming trace, lifting the limitations by internal buffers and slow data transmission to give you all the insights you need to develop and optimize your code.


J-Trace PRO can capture complete traces over long periods—thereby enabling the recording of infrequent, hard-to-reproduce bugs. This is particularly helpful when the program flow ‘runs off the rails’ and stops in a fault state.

It also supports extended trace features, such as code coverage (so engineers have visibility over which parts of the application code have been executed) and execution profiling (providing visibility as to which instructions have been executed and how often—so hotspots can be addressed and optimization opportunities identified).
