Safety Analysis and Design for ISO 26262 - Model Based and Tool Supported 2013-01-0193

Modern development processes put architecture and design models in the center of system engineering activities. With the increasing application of software (SW) controlled functions such development processes have obtained a high significance in the automotive industry too. In addition, functional safety standards such as ISO 26262 [1] issued by International Standardization Organization (ISO) require safety analysis procedures to be tightly integrated with these engineering activities. The authors show a solution to tackle the need for such integration by using architecture and design models as a single source of information for functional safety analysis activities and methods. Moreover, a seamless round-trip approach between the activities of the system design, the requirements engineering and the functional safety analysis activities is presented.
