A new feature of Lauterbach's TRACE32 tools is the ability to export task event-based trace data for external timing analysis. This is done by extracting the real time task event based trace data from the program flow. This data is recorded in the TRACE32 hardware as part of the hardware based trace flow, for example via NEXUS or ETM.
TRACE32 trace tools provide fast and efficient troubleshooting capabilities to detect complex errors that only occur during run-time conditions. With the latest Trace32 technology, the recorded program/data flow is time stamped to allow an overall analysis of the system performance, as well as quality assurance features such as code coverage, cache analysis and timing analysis.
The extracted data contains task event information and time information and can be saved and exported in CSV format, which can then be used by any external timing analysis and verification tool that supports this file format. It is then possible to analyse the timing data to perform worst-case analysis, peak loading and many other parameters to help with optimizing the design. This feature was developed for AUTOSAR but can be applied to many other environments.
