Comments on the ICT strategy paper: • Most of the important issues for an European ICT Strategy are covered by the Paper • With respect to critical embedded control systems, the following aspects should be emphasized more: • “Functional Safety” and “Reliability/Availability” Aspects • System validation, evaluation and certification (standards !) • Holistic system view, merging of safety and security considerations, basic dependable infrastructures on core-service level (e.g. TTP/C, …) • Examples from the DES-Roadmap (EU - AMSD project) “technical safety applications” vs. “fun and entertainment world” ERCIM – Strategy Paper on European ICT WG “Dependable Software-Intensive Embedded Systems”University of Malaga, Nov. 3rd, 2004
Characteristics of Embedded Systems • Embedded Systems: Combination of processors, sensors, actuators, “intelligence”, “hidden computers” and massive deployment, intensive interaction with uncertain environment: “A physical process with dynamics, fault, noise, dependability, power, size (in general: resource -) and memory restrictions…” (Foundational Infrastructure needed) • Embedded Software: new capabilities to HW transducers added by “embedded software” (“defines physical behaviour of a complex non-linear device”), HW/SW co-design, dependability, low power, timeliness, … characteristics Systems are NOT always safety-critical by definition – often the actual criticality and dependability levels rise based on our desire for enhanced reliance on them !! (Human Factors – safer cars imply more aggressive driving behaviour after some time) Security Aspects often neglected by Safety Design Engineers, and vice versa !!
Application Assessment Human centered, Vision-Driven, Safety? • Automotive: Accident free Driving • Avionics: Safe Sky for Europe • Medical: Robot Surgeon • Communications: Seamless Connectivity • E-Life: Ubiquitous Computing, environment awareness • personalised (user centered, dynamically adapted to user preferences), • dependable (time dynamics, timely responsiveness, secure), • context-awareness(person, object, location, time), • natural interaction Industrial Vision: „Aerospace Safety at Automotive Cost“ Industrial Need: From Supply Chain to Design Chain
Trends in Medical SystemsComponent Healthcare System Around us ... Micro-capsule Products and equipment at the service of individuals … inside us ?
Trends in Automotive (on-board embedded systems) Three groups of trends: • Advanced comfort • e.g. Car Body Electronics (adaptive equipment: seats, superposed adjustable steering wheel, (no) pedals, ….) • Noise suppression, adaptive air conditioning, configurable cockpit, …. • Navigation, communication, information, new types of displays • Safety enhancement • Vehicle Dynamics (ABS, ASR, ABC, ESP (Electronic Stability Program), AAS (Active Additional Steering), Adaptive Cruise Control, Road Tire friction Control, …) …. Safety – critical controls ! • Advanced Warning- and Control Systems (pedestrian protection, crash avoidance, track control, lane support, …) …. Safety – critical controls ! • Driver Monitoring, Predicitive Driver Assistance, Emergency call system • Optimized resource usage • Power Train (Integrated Engine Control, Transmission Control) …. Safety – critical controls ! • Fully integrated Electrical Energy Management
Extending autonomous on-board functions with interactive and co-operative systems: • Roadside embedded systems and interaction (intersection, speed control, emergency call systems) • Local connectivity: vehicle – to –vehicle (long term) – highway throughput optimization, advanced adaptive cruise control • Global Connectivity: Satellite, traffic navigation and control Ultimate Goal: Autonomous Driving, “Platooning” of vehicles • Liability, Legal and Standardization Issues !! • Linking of local to global infrastructures: Link to “Ambient Intelligence” • Security Issues: Connectivity during Operations & Maintenance !! (Call-back, Upgrades off-line or on-line ?) • Enabling Technology for all of these trends: DES !! Trends in Automotive (eSafety on the road)
Trends in Automotive Less mechanics does not only allow lighter, cheaper, safer, environmentally more sustainably operating cars, but also incredibly NEW CARS ! (Examples: DaimlerChrysler F300, F200, F500). Obstacles to mass deployment – electronic/SW failures up to 55% !!
DES Challenges Major Issues in System & Software Technology • Requirements Engineering, with respect to Dependability, • Model Based Development • Reuse/COTS/Composability/Scalability wrt. Dependability • Standardisation (cost, maintainability, interoperability) • (Modular) Certification, component-based Safety Case • Dynamic Environments (ubiquity/nomadicity - mobility, low power) • Systematic Testing, Validation and Certification • Temporal Predictability (TTP) vs. Uncertainty • Human Factors (HCI) • SoC: Shrinking feature size, new failure modes • Diagnosis and Maintenance: Autoconfigurability, Plug & Play, Diagnosis Dependability: The 10-9 Challenge can only be managed by an architectural approach (components about 10-4 to 10-5 only – the system is more dependable than each of its components !)
DES - Challenges Safety Systems Concerns: • resources shared between functions (encapsulation of task environs) • stronger interactions among them • more functionality at less cost (cost explosion in development ?!) Safety is a system property: • New hazards arise from fault propagation in composed systems and unintended emergent behaviour Need for modular Safety Analysis and Certification, depending on • Partitioning • Safety Function • Controlled Failure
DES Challenges Trends in component-based DES: Development of semi-standardized components, packaged with a certification argument or “pre-certified” System calibration will become largely a composition of component-level pre-certification arguments Foundational infrastructure required: Time Triggered -paradigm – Fundamental Progress achieved during the last years !! • Building Blocks for HRT Middleware, • System Simulation and Emulation (Co-Design/Co-Simulation), • Performance Modeling
DES Roadmap – Synthesis COTS, Sensors: Enormous challenge and chance for SME’s !!!! • Standardise sensorial interfaces • Standardise API, architecture and external behaviour of IP components, HW/SW Design – IP protection !! • Debugging facilities, Diagnosis (transient vs. permanent faults) • Intra component V&V • Inter component V&V • Composability and reusability • Safe reuse of COTS software: certification, sufficient understanding of system and environment (both original and target) to identify when software is used outside the “operational envelope” for which it was originally designed and tested; • Confirmation, that COTS does not other (unexpected) things as well (hierarchical verification via functional refinement may be inadequate, notions of architectural refinement may provide better verification).
Economic Impact of DES (examples) • Electronics in Cars: 170 billion € HW, 100 b € SW (2010), Europe in leading position • Driver assistance systems: 2-3 b € 2007, increasing by 50% within a few years • Aerospace industry revenues: 265 b € total, 70 b € civil, Europe in leading position • European mechanical Engineering Industry: 353 b € turnover, 129 b € exports, 32% of innovations DES-based (HW, SW) rising to 40% • SMEs in active safety systems electronics consultation and know-how transfer services in the validation and certification market: 5 b € (2010), annual growth about 30% • Tool and component manufacturer: annual increase expected in DES market by 20% - 40 %, depending on sector. • Environmental, Quality and Safety of Life, Employment impact expected to be considerable large by means of DES – mass deployment
