Easily add automatic stack analysis to your development process

Fully automated stack-usage analysis for TargetLink-generated code

StackAnalyzer supports tight integration with TargetLink, the production-code generation tool from dSPACE.

TargetLink automatically generates production code for graphically specified functions straight from MathWorks MATLAB/Simulink/Stateflow. This drastically shortens coding and development time and contributes to a consider­able improvement in the quality of the pro­duction code.

TargetLink is certified for functional safety standards such as ISO 26262, ISO 25119, and IEC 61508.

Your benefits

• The maximum stack usage of each TargetLink root function can be viewed directly in TargetLink.

• By making this implementation-level property visible at the modeling level, you can detect errors and bugs early in the development process, avoiding late-stage integration problems.

• The static analyzer does not require the system under test to be executed on a hardware proto­type. Results are available quickly, no dedicated hardware is needed.

• The analyzer works on the generated code and provides full control and data coverage. This enables safe upper bounds on worst-case stack usage to be computed.

• The static analysis can be invoked automatically from the TargetLink GUI and run in batch mode. This makes it easy to run an analysis after each model change, if desired.

• Navigating from the source code to the corresponding model component is possible with a single mouse click. This simplifies alarm analysis and en­ables direct error tracing between implementation and model level.

• Relevant model-level information is automatically propagated to the analyzer to enable tighter analysis results and avoid double inputs.

Workflow

The automated flow between TargetLink and StackAnalyzer provides for a seamless integration into the de­velopment cycle.

AbsInt and dSPACE cooperated on the integration in the TIMMO-2-USE project that addressed the specification, transition and exchange of relevant timing information through­out different steps of the AUTOSAR-based development process and tool chain.
