TRACE32® Exports Task Event Based Trace Data for External Timing Analysis
Hoehenkirchen-Siegertsbrunn, June 2014 - Lauterbach, the leading manufacturer of microprocessor development tools, has recently announced a new feature of its TRACE32® tools - Exporting Task Event Based Trace Data for External Timing Analysis.
The TRACE32 trace tools provide fast and efficient trouble shooting capabilities to detect complex errors that only occur under run-time conditions. In addition 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.
Timing is essential to the success of real-time embedded system development. This new feature of TRACE32 tools supports the requirements of quality standards by providing proof of timing and code performance. 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 HW based trace flow, e.g. NEXUS, ETM etc.
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 optimising the design. This feature was developed for AUTOSAR but can be applied to many other environments.
