xtUML and the Notion of Time

Overview

New UML users typically come from a design background where the implementation language emphasizes sequential processing, strict concurrency, and synchronous communication. Consequently, these new users produce models that are prepared at low levels of abstraction and often contain elements that are platform specific. As abstraction is raised, the greatest difference is in the treatment of time, where precise clocks and global synchronicity are replaced by the fuzzy ideas of order and pair-wise synchronicity. This presentation explores these ideas in the xtUML context and discusses how to construct models that avoid common pitfalls which lead to race conditions and intermittent instability.

What You Will Learn

  • What does time mean in a platform-independent model?
  • How does xtUML represent time?
  • What are some common pitfalls?

  • What capabilities are available in BridgePoint Verifier that will help identify timing-related issues?

Who Should Attend

  • Systems Engineers
  • SW Engineers/SW Architects
  • HW/Electrical Design Engineers
  • Systems Designers
  • Projects Managers for Systems Projects
