3. Proprietary Information Rockwell Collins France AESE – GeneAuto – 23-09-09 3 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

4. Proprietary Information Rockwell Collins France AESE – GeneAuto – 23-09-09 4 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

6. Proprietary Information Rockwell Collins France AESE – GeneAuto – 23-09-09 6 Summary of results ObjectivesResultsComments Code generation and compilation OKThe code has been generated then compiled with GCC compiler without any trouble Functional behavior (25 tests cases) 16 PASSED 9 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 MBD library blocks are currently supported Gene-auto may be modified easily to add new features so that 100% of MBD library blocks used at RCF would be supported.
