The visualization approach for Component Fault Trees (CFTs) realized in this work was implemented as an extension of the safeTbox modeling tool (safeTbox.de). Its goal is to enhance the understandability of compositional and hierarchical models while facilitating reviewing purposes. Safety Analysts makes use of CFTs to perform fault analyses at system level. However, such analyses are hindered by the traditional approach of hiding the realization information of components behind the specification views. The approach presented here overcomes this problem thanks to an information-based zoom. Through it, it is possible to gradually present at the specification level information extracted out of the internal realization views.
