“…While there seems to be a general consensus on (a large portion of) the static semantics of UML, the dynamic semantics of its behavioral diagrams, such as activity diagrams, interaction overview diagrams, and state machines, is still an open problem [Broy and Cengarle 2011]. The works that address the behavior of UML models only focus on a limited number of diagram types (oftentimes, they only consider a single type) and neglect the interdependencies with the other diagrams of a system.…”

This paper presents a novel technique to formally verify models of real-time systems captured through a set of heterogeneous UML diagrams. The technique is based on the following key elements: (i) a subset of UML diagrams, called C-UML, which allows designers to describe the components of the system and their behavior through several kinds of diagrams (e.g., state machine diagrams, sequence diagrams, activity diagrams, interaction overview diagrams), and stereotypes taken from the UML MARTE profile; (ii) a formal semantics of C-UML diagrams, defined through formulae of the metric temporal logic TRIO; (iii) a tool, called Corretto, which implements the aforementioned semantics and allows users to carry out formal verification tasks on modeled systems. We validate the feasibility of our approach through a set of different case studies, taken from both the academic and the industrial domain. CCS Concepts: •Software and its engineering → Model-driven software engineering; Model checking; Unified Modeling Language (UML);

“…Some notations like B (Abrial, 1996), Z (Spivey, 1992) or Alloy (Jackson, 2006) are designed specifically for analysis purposes, and hence come with a built-in formal semantics. Meanwhile, other general purpose notations like UML require a previous formalization step before committing to analysis (Broy and Cengarle, 2011).…”

“…RELATED WORK Researchers have been trying to ascribe UML with many different semantics, but all these attempts have been partial. While there seems to be a general consensus on (a large portion of) the static semantics of UML, the dynamic semantics of its behavioral diagrams, such as activities, interactions and state machines, is still an open problem [5].…”

UML is a general-purpose modeling language that offers a heterogeneous set of diagrams to describe the different views of a software system. While there seems to be a general consensus on the semantics of some individual diagrams, the composite semantics of the different views is still an open problem. During my PhD I am considering a significant and consistent set of UML diagrams, where timed-related properties can be modeled carefully, and I am ascribing them with a formal semantics based on metric temporal logic. The use of logic is aimed to help capture the composite semantics of the different views efficiently. The result is then used to feed a bounded model/satisfiability checker to allow users to verify these systems, even from the initial phases of the design. The final goal is to realize an advanced modeling framework where users can exploit both a well-known modeling notation and advanced verification capabilities seamlessly.
