A Quality Requirements Safety Model for Embedded and Real Time Software Product Quality

safety requirements quality is typically expressed at the software system levels, which may lead to specific safety-related functions that may be applied in either or both hardware and software. According to the Previous work of academia and industry standards such as ISO 25021 square series safety requirements can be defined and measured internally and externally; the internal safety concepts could include control software hazards, safety levels of software integration and critical software catastrophic, while the external safety could include software safety functions, safety failure mechanism and safety switching of redundant items. This paper collects and organizes these safety-related requirements into a quality requirements safety model for identifying and evaluation of the quality safety requirements of embedded and real time systems..
