1. A method comprising: analyzing, using a computational device, execution results of a model to identify an execution sequence of the model, the execution results including execution results from a plurality of sample times, the execution sequence leading to a failure condition of the model; identifying, using the computational device, a portion of the model that contributes to the failure condition based on the identified execution sequence; and displaying, using the computational device, the identified portion of the model differently than other portions of the model that do not contribute to the failure condition of the model.
