MODIFI is a fault injection tool targeting software developed as Simulink models. In this paper, we describe three techniques for visualizing fault injection results obtained using the MODIFI tool. The first technique shows the progress of a fault injection campaign, and the outcome of individual experiments, using a 3D visualization of the fault injection campaign. The second technique, referred to as sensitivity profiling, identifies parts of a model that are sensitive for a specific fault model. The third technique shows how error propagates in a Simulink model. The sensitivity profiling and error propagation techniques are based on intuitive coloring of Simulink blocks. The three visualization techniques are demonstrated using a Brake-by-Wire system.
