The context

• GeneAuto was evaluated by the Helicopter cockpit development team (1st quarter CY09)– Two phases

• Technical evaluation• Integration in RC ADAPT methodology + certification issue

• Targets– Introduce GeneAuto in industrial developments in CY2010– Future integration in a complete open-source MBD environment

Experimentation on use cases models

• The validation of use-cases consists in testing the following capabilities of the Gene-Auto tool on some

• use-case models. The following tests were performed on input models:– Capability to generate code out of the input model– Capability to compile the code– Code performances ( in regard of RTW)– Functional testing– Capability to integrate generated code with external code (manual

or auto-generated)– Traceability check

• Code / model• Code / requirements (DOORS)

– Correctness of code

Summary of results

Objectives Results Comments

Code generation andcompilation

OK The code has been generated thencompiled with GCC compiler withoutany trouble

Functional behavior(25 tests cases)

16 PASSED9 FAILED

4 FAILED due to 1 bug (cast)5 FAILED due to 1 bug (init stateflow)2 bugs found which can be corrected

Performance of the generated code (compared with RTW)

CPU throughput :+/- 5%Memory : +100%

Gene-auto code generated today without any optimization. These performances could be optimized by:· Providing optimized and specific Simulink blockset (not generic)· Optimizing backend classes for blocks in Gene-Auto· Adding some optimization modules in the CodeModelOptimizer elementary tool of gene-auto.

Compatibility with RC MBD Library

67% of AW149 MBDlibrary blocks arecurrently supported

Gene-auto may be modified easily toadd new features so that 100% of MBDlibrary blocks used at RCF would besupported.
