Fast Functional Safety Verification for Distributed Automotive Applications During Early Design Phase
IEEE Transactions on Industrial Electronics, 2018Co-Authors: Gang Zeng, Renfa Li, Jia Zhou, Keqin LiAbstract:Both response time and reliability are important Functional Safety properties that must be simultaneously satisfied learning from the automotive Functional Safety standard ISO 26262. Safety verification pertains to checking if an application meets a safe set of design specifications and complies with regulations. Introducing verification in the early design phase not only complies with the latest automotive Functional Safety standard but also avoids unnecessary design effort or reduces the design burden of the late design optimization phase. This study presents a fast Functional Safety verification (FFSV) method for a distributed automotive application during the early design phase. The first method FFSV1 finds the solution with the minimum response time under the reliability requirement, and the second method FFSV2 finds the solution with the maximum reliability under the response time requirement. We combine FFSV1 and FFSV2 to create union FFSV (UFFSV), which can obtain acceptance ratios higher than those of current methods. Experiments on real-life and synthetic distributed automotive applications show that UFFSV can obtain higher acceptance ratios than their existing counterparts.

Hardware Cost Design Optimization for Functional Safety-Critical Parallel Applications on Heterogeneous Distributed Embedded Systems
IEEE Transactions on Industrial Informatics, 2018Co-Authors: Yuekun Chen, Renfa Li, Keqin LiAbstract:Industrial embedded systems are cost sensitive, and hardware cost of industrial production should be reduced for high profit. The Functional Safety requirement must be satisfied according to industrial Functional Safety standards. This study proposes three hardware cost optimization algorithms for Functional Safety-critical parallel applications on heterogeneous distributed embedded systems during the design phase. The explorative hardware cost optimization (EHCO), enhanced EHCO (EEHCO), and simplified EEHCO (SEEHCO) algorithms are proposed step by step. Experimental results reveal that EEHCO can obtain minimum hardware cost, whereas SEEHCO is efficient for large-scale parallel applications compared with the existing algorithms.

Reliability Enhancement Toward Functional Safety Goal Assurance in Energy-Aware Automotive Cyber-Physical Systems
IEEE Transactions on Industrial Informatics, 2018Co-Authors: Guoqi Xie, Renfa Li, Hao Peng, Zhetao Li, Jinlin Song, Yong Xie, Keqin LiAbstract:Automotive cyber-physical systems are energy-aware and Safety-critical systems where energy consumption should be controlled from a perspective of design constraints and reliability should be enhanced toward Functional Safety goal assurance. In this paper, we solve the problem of reliability enhancement of an automotive function (i.e., Functionality or application) under energy and response-time constraints based on the dynamic voltage and frequency scaling technique. The problem is solved by a two-stage solution, namely, response-time reduction under energy constraint and reliability enhancement under energy and response-time constraints. The first stage is solved by proposing average energy preallocation, and the second stage is solved by proposing a reliability-enhancement technique based on the first stage. Examples and experiments show that the proposed solution can not only assure energy and response-time constraints, but also enhances reliability as much as 16.66% compared with its counterpart.

trident architectural views a pattern for dependable systems design
European Conference on Pattern Languages of Programs, 2015Co-Authors: Christian KreinerAbstract:The TRIDENT ARCHITECTURAL VIEWS pattern is a systematic approach to architecting complex dependable systems. While engineering system Functionality through several steps of refinement with full traceability is well established, dependability attributes like Functional Safety and IT security are hard to control during the creative steps of design. TRIDENT ARCHITECTURAL VIEWS has been mined primarily from best practices in engineering of systems exhibiting Functional Safety. It provides a three-view framework with Functional, Element, and Composition together with nine relations that guide architecture work for dependable systems.

2016Co-Authors: David J. Smith, Kenneth G L SimpsonAbstract:The Safety Critical Systems Handbook: A Straightforward Guide to Functional Safety: IEC 61508 (2010 Edition), IEC 61511 (2016 Edition) & Related Guidance, Fourth Edition, presents the latest on the electrical, electronic, and programmable electronic systems that provide Safety functions that guard workers and the public against injury or death, and the environment against pollution. The international Functional Safety standard IEC 61508 was revised in 2010, and authors David Smith and Kenneth Simpson provide a comprehensive guide to the revised standard, as well as the revised IEC 61511 (2016). The book enables engineers to determine if a proposed or existing piece of equipment meets the Safety integrity levels (SIL) required by the various standards and guidance, and also describes the requirements for the new alternative route (route 2H), introduced in 2010. A number of other areas have been updated by Smith and Simpson in this new edition, including the estimation of common cause failure, calculation of PFDs and failure rates for redundant configurations, societal risk, and additional second tier guidance documents. As Functional Safety is applicable to many industries, this book will have a wide readership beyond the chemical and process sector, including oil and gas, machinery, power generation, nuclear, aircraft, and automotive industries, plus project, instrumentation, design, and control engineers. Provides the only comprehensive guide to IEC 61508, updated to cover the 2010 amendments, that will ensure engineers are compliant with the latest process Safety systems design and operation standardsAddresses the 2016 updates to IEC 61511 to helps readers understand the processes required to apply Safety critical systems standards and guidancePresents a real-world approach that helps users interpret new standards, with case studies and best practice design examples throughout

Implementing Functional Safety Standards - Experiences from the Trials about Required Knowledge and Competencies (SafEUr)
Communications in Computer and Information Science, 2013Co-Authors: Richard Messnarz, Ovi Bachmann, K. Dussa-zieger, Risto Nevalainen, Christian Kreiner, Serge TichkiewitchAbstract:In the EU project SafEUr (518632-LLP-1-2011-1-AT-LEONARDO-LMP) the partnership developed a skill set with learning objectives, training materials, and tools to teach and coach the implementation of IEC 61508 and ISO 26262. Automotive, Medical, and Nuclear industry gave inputs to the project. A group of above 20 multinational companies (SOQRATES www.soqrates.de) which also are active in automotive industry (some of them represent the largest suppliers in Automotive industry) organised reviews and trial courses with Safety managers. This led to a defined set of skills and tools we expect from Functional Safety managers and Functional Safety engineers. In this paper we describe the results of SafEUr, the feedback we received from the collaboration with leading automotive industry and the next steps in 2013 to launch this schema with official certificates from end of 2013 onwards.
