  1. Multidisciplinary Modelling: Current status and expectations in the Dutch TWINS consortium {F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers }@tue.nl ICSSEA’08 Ecole Nationale Supérieure des Télécommunications Paris, France, December 9, 2008

  2. Motivation Growing number of SW-HW embedded machines Many disciplines, mono-disciplinary focus Shorter time to market, growing complexity, increasing product quality Problematic integration trajectory ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  3. ITEA TWINS Project Goals multidisciplinary modelling • Communication • Consistency • MDA/MBD/MDTE • Understand physics • Control synthesis • Verify models • … TWINS: Optimizing HW-SW Co-Design Flow for Software Intensive System Development ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  4. Partners ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  5. Approach for investigation topics Obtained by: Project requirement analysis Use case analysis Plenary meetings 5 topics: Testing Verification Simulation Model Driven development Multi-disciplinary development language ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  6. Current industrial practices • Design phase • Product Development • System Design • Decomposition • Integration phase • System verification phase • Observation • Simulation • Formal verification ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  7. Design Phase – Product Development V-model ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  8. Design Phase – Product Development CAFCR ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  9. Design Phase – Product Development V-model extensions Contribution to harmonization between disciplines Accessible, understandable, readable Manage track-and-trace development Hard to remove inconsistency Difficult to trace the precise progress ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  10. Design Phase –System Design Purpose: • Communication for stakeholders/engineers • Project management • Risk reduction • System correctness Requirement types: • Functional • Non-Functional ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  11. Design Phase – System Design Decomposition Mechanical Behaviour Design Software Design System Requirements Static Physical Design Electrotechnical Design ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  12. Design Phase – System Design Decomposition – System Requirements Problem Frames ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  13. Design Phase – System Design Decomposition – Mechanical Behaviour Designs Chi CB/DE ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  14. Design Phase – System Design Decomposition – Software Designs UML ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  15. Design Phase – System Design Decomposition – Static Physical Designs CAD ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  18. Integration phase –Current approaches ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  19. System verification phase • System design level • Integration level • Realisation level ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  20. Technical Contribution ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  21. Results Tools depend on industrial field Tools have mono-disciplinary focus Tools are vendor locked Models used are non-formal Multi-disciplinary model can reduce test time Cohesion between partners methods ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers

  22. Questions ICSSEA'08 - F.P.M.Stappers, L.J.A.M.Somers, M.A.Reniers
