Signature required: Making Simulink data flow and interfaces explicit

Model comprehension and effective use and reuse of complex subsystems are problems currently encountered in the automotive industry. To address these problems we present a technique for extracting, presenting, and making use of signatures for Simulink subsystems. The signature of a subsystem is defined to be a generalization of its interface, including the subsystem's explicit ports, locally defined and inherited data stores, as well as scoped …
