Symtavision and Lauterbach integrate flow.

Symtavision and Lauterbach have further integrated the SymTA/S and TraceAnalyzer timing design tools with Lauterbach’s TRACE32 suite of microprocessor development tools.

The workflow, which enables real-time traces from TRACE32 to be imported and analysed using SymTA/S and TraceAnalyzer has been improved to facilitate better support of rich traces with wait and release behavior, the import of traces with runnable activity within tasks and the ability to import and analyze functional-level traces generated by TRACE32.

With the Symtavision / Lauterbach joint workflow, code for automotive ECUs is imported into TRACE32 from any third party ECU configuration tool for target debugging, emulation and software validation.

Trace data from ECU measurements or hardware independent simulations is then passed to TraceAnalyzer to visualize and analyze timing traces and validate ECU scheduling. The resulting timing models can be processed further in SymTA/S to perform worst-case and statistical timing analysis, as well as to virtually change the scheduling and explore / optimize the overall software architecture.

The optimised configuration is then passed back to TRACE32 via the third party ECU configuration tool and uploaded to the target, completing the round-trip workflow.
