States, events, and output signals are examples of such objects. Such that humans need to handle only a small number of objects at any time.īehavioral hierarchies: Behavioral hierarchies are hierarchies containing objects necessary to describe the system behavior. Hierarchy (in combination with abstraction) is a key mechanism helping to solve this dilemma. The description of all real-life systems needs more objects than humans can understand. Humans generally cannot comprehend systems containing many objects (states, components) having complex relations with each other. Languages should be capable of representing the following features: Footnote 1 A model is minimal with respect to a task if it does not contain any other characteristics than those relevant for the task”. The model contains exactly those characteristics and properties of the modeled entity that are relevant for a given task. “ A model is a simplification of another entity, which can be a physical thing or another model. Specifications for such systems provide models of the system under design (SUD). 1.8), we will first of all describe requirements and approaches for specifying embedded and cyber-physical systems.
Consistent with the simplified design flow (see Fig.
