Trace conversion
- Support for the Infineon MTV TAB trace format.
- Interactive MCDS tracing via Infineon DAS on TriCore AURIX devices.
- Improved interrupt handling and trace coverage for PPC NEXUS traces.
- Task switches can now be detected by specifying the memory cell that contains
the current active task ID. You can specify using the global attribute
running_task:attribute "running_task": address(("osKernelVariables"."ossActiveTaskIndex")); - Routines can now be excluded from the analysis using the annotation
not analyzed. The analysis then only considers the trace time for these routines. - Traps are now handled like external routines.
- Improved handling for the GHS code factor optimization.
TimeWeaver analysis
- Performance improvements for trace-based path analysis.
- Improved loop scaling conflict detection.
- Traced execution times spent inside routines declared as external
(using
not analyzed) are now accounted for the annotated routine instead of the calling routine. - Implemented support for overriding traced execution times of not-analyzed routines
via the
takesannotation. - The analysis results can now be used in ResultCombinator.
Extended statistics
TimeWeaver statistics now include a polar chart view for trace segment and duration of interrupts.
