The latest version of the Dspace TargetLink automatic code generation software is scheduled for launch in early 2003.
The latest version of the Dspace TargetLink automatic code generation software is scheduled for launch in early 2003.
The new TargetLink 2.0 will enable the auotmatic generation of highly efficient production code from Matlab, Simulink and Stateflow, and has been considerably extended compared with the previous version of the tool.
Numerous innovations will boost efficiency and cut the development times of electronic control units (ECUs).
Included among these major new innovations will be the generation of code for OSEK/VDX-compliant real-time operating systems from Matlab/Simulink, the new Dspace Data Dictionary for model-independent data management and an innovative tool for automatic scaling of models by the worst-case method.
Other efficiency-boosting features will include a new blockset concept that makes teamwork more cost-effective and incremental code generation, which allows code generation for a specific subsystem in which a modification has been made.
TargetLink is easy to integrate into existing development environments and will offer code coverage analysis at a mouse-click without any other tool required.
Furthermore, TargetLink 2.0 will provide a new freely installable blockset that allows models to be exchanged even without a TargetLink licence.
Support of OSEK/VDX-compliant operating systems will be another of TargetLink 2.0's major new features.
OSEK operating system objects and services can be specified on block diagram level and TargetLink will generate all the code.
The new Dspace Data Dictionary is a central data container that holds all the information relevant to code generation, independently of model partitioning.
In future, the Dspace Data Dictionary will be connected to other tools within the Dspace tool chain to ensure consistent data management throughout the entire development process.
In conjunction with TargetLink 2.0, it will simplify data storage for complex ECU development and support teamwork in project groups.
Worst-case autoscaling will dramatically shorten the time developers need for fixed-point scaling.
Plant models and stimulus signals will no longer be required.
The developer can specify value ranges and data types at model boundaries.
TargetLink will then propagate these through the model, after which scaling is performed by the worst-case method.
The new blockset in TargetLink 2.0 can be installed and used on any computer that also has Matlab/Simulink installed.
This means that models can be exchanged freely without the need for extra TargetLink licenses.
Thus TargetLink will be able to be used cost-efficiently by several developers at once.
