Abstract: The ISO 26262 road vehicle-functional safety is a standard to conduct product functional safety design as core task and also include the manufacturing in the product safety lifecycle. Since packaging and testing processes are the important part of the semiconductor manufacturing, this research in this paper focuses on the functional safety task linking from IC design to packaging and testing, including, how packaging houses provide package failure rate estimation to chip designer to evaluate hardware architecture metrics and probabilistic metric for random hardware failures to determine compliance with functional safety design; The critical safety parameters defined in design are properly controlled in the mass production to ensure the realization of functional safety design on the product ; Evaluating the confidence in use of software tool used in package design and test software design, and enhancing the reliability of the package to reduce the failure rate.

Key words: functional safety, failure rate estimation, hardware architecture metric, probabilistic metric for
