Products containing hardware parts with ASIL B or higher levels must perform quantitative assessments of random hardware failures to ensure that they are within the target values. The FMEDA technique is used for this quantitative assessment. To perform FMEDA, input parameters like basic failure rate values, failure mode and failure mode distribution rates for safety-related components, and diagnostic coverage values for safety mechanisms must be prepared. This paper deals with the method of calculating the basic failure rate, deriving the failure mode, and calculating of the failure mode distribution, excluding the diagnostic coverage value of the safety mechanism. |
