Abstract
Example implementations as described herein are directed to generate a fault tree with a design document and minimized rules or database. The fault tree generation system may utilize assembly data and ladder programs as input and generates a fault tree by connecting an upper part of the fault tree generated from an assembly tree structure in the assembly data and a lower part of a fault tree from control logic in the ladder program. The fault tree is generated by connecting the lower part of the tree of the fault tree from the logic.
