ISO 26262을 위한 저가 MCU기반 소프트웨어 플랫폼 설계

The automotive E/E system is faced with various requirements increase and the short development time. Therefore, the latest software architecture needs to design a reusable platform and a standard platform. Besides, ISO26262 and IEC 61508 require Safety mechanism. So a legacy software platform has to develop the functional safety that is defined ISO26262 and IEC 61508. In order to combine a using software platform and safety mechanisms, it is defined and analyzed failure modes of developed software platform. But to apply the safety mechanism of highly diagnostic coverage, these are composed of special HW and redundancy mechanisms. The case leads to increase the unit cost. So it is important to select compatible safety mechanisms for measuring failure modes. This paper suggests safety mechanisms that apply to a low grade MCU and design guide-lines in a development process.
