Abstract

Design abstraction is a method to reduce state space sizes of software verification models; it allows also large software models to be verified. Design abstraction has long been used in conjunction with text-based approaches to software modeling and verification. Its use together with graphical such approaches is less common: most graphical modeling notations provide weaker support for design abstraction than text based notations do. This makes verification of large graphical models more difficult than verification of large text-based models. This paper shows how the graphical software modeling notation UML may be used to express some of the design abstractions that arise when large UML requirement models are subject to formal verification. The paper presents a dialect of UML to support design abstractions and exemplifies its use for requirements modeling of an embedded systems specification.
