Abstract

A method includes: receiving classification data for a hazard associated with a system of a vehicle, the classification data indicating a classification of the hazard under standard 26262 of the International Organization for Standardization (ISO); receiving fault tree data for a fault tree of the hazard; analyzing the fault tree data using a fault tree analysis (FTA) application; identifying a minimal cut-set for the hazard; retrieving standards data for the hazard based on the classification of the hazard, the standards data indicating a minimum value for minimal cut-sets under the 26262 standard; comparing a number of elements in the minimal cut-set with the minimum value; and indicating whether the minimal cut-set complies with the 26262 standard based on the comparison.
