  1. Introduction More and more complex electronics and software: • To enable innovation • To decrease costs • To fulfill legal needs (e.g. CO2 emission) etc. How to ensure consistency among different views? / Department of Mathematics and Computer Science 03/10/14 PAGE 1

  2. ISO/IEC/IEEE 42010 Conceptual Model of an Architecture Description Architecture description language (ADL) Architecture framework

  3. Architecture Framework for Automotive Systems (AFAS) PAGE 3

  4. Architectural correspondence PAGE 4

  5. Correspondence Rules / Department of Mathematics and Computer Science 03/10/14 PAGE 5

  6. Consistency Semantics Semantic differences between dependency and composition refinements 03/10/14 PAGE 6

  7. Consistency Semantics / Department of Mathematics and Computer Science 03/10/14 PAGE 7

  8. Evaluation • Adaptive Cruise Control / Department of Mathematics and Computer Science 03/10/14 PAGE 8

  9. Consistency checking tool A consistency-checking for automotive architectural models: PAGE 9

  10. Evaluation on Adaptive Cruise Control 03/10/14 PAGE 10

  11. ACC system model • ACC is split into: • ACC_UI (SW) • ACC_Controller (HW) • SW-model is made in IBM Rhapsody • HW-model is made in Matlab Simulink 03/10/14 PAGE 11

  12. ACC hardware models • 3 Hardware models • Radar model • Powertrain model • ACC model • Hardware models are unit tested in Matlab 03/10/14 PAGE 12

  13. System integration • Software • Hardware 03/10/14 PAGE 13

  14. Evaluation 03/10/14 PAGE 14

  15. Conclusion and Future work • Automotive Architectural Views defined • Automotive architecture consistency rules defined IBM Rhapsody tool plugin developed • Need to formalize other correspondence rules • Need to support consistency between automotive ADLs (e.g. between SysML and MATLAB/Simulink, Stateflow) PAGE 15

  16. SysML/Simulink Model Sync Old generated code snippet New generated code snippet • Input/Output ports of a SimulinkBlock is updated after importing both updated Simulink model and the newly generated code (only updated Simulink MDL file is not enough).
