Validate Your Requirements Through Modeling with DOORS and Rhapsody

By integrating a model driven development environment with requirements-driven development, a developer can ensure that their design meets the requirements completely. Telelogic will show how this can be done with a webcast titled, “Validate Your Requirements Through Modeling with DOORS and Rhapsody.”

The webcast will demonstrate how Telelogic DOORS works with Telelogic Rhapsody to create today’s best practice for controlled, efficient development. With DOORS and Rhapsody, developers can easily visualize, model, and validate requirements to ensure that the design meets the requirements earlier in the lifecycle, all the way down to the source code and tests.

The live Webcast and product demonstration will show how DOORS and Rhapsody can help:

  • Improve communication and understanding of requirements through visualization
  • Ensure conformance with customer needs and compliance with regulations met through traceability from requirements to design models
  • Determine the impact of requirements changes on designs to ensure nothing is overlooked
  • Validate requirements with stakeholders through simulation of models

The online seminar will take place Wednesday October 18th, 2006 at 8:00am PT (11:00am ET/4:00pm GMT).

UML in SoC Hardware-Software Design

This article describe the problems facing developers of embedded system-on-chip hardware and software and how executable UML can help. As with most of the hardware-oriented C variants, one solution to the problem of taking a software-oriented language for use in SoC is to add hardware features to it. The same has been proposed for UML, but the authors propose the opposite: use only the minimum necessary to specify system functionality.

Model mappings, coupled with marks that indicate which mapping rule to apply, are then used to translate the application model into hardware and software description languages. This approach enables a major simplification of the use of UML in SoC, and corresponding simplification of the work of SoC developers.


SysML Online Seminar

The SysML consortium has almost finalized the Systems Modeling Language (SysML) specification. SysML is based on a subset of UML 2.0 with some key additions to make it more systems friendly. I-Logix has been actively engaged in the dialog about SysML, having contributed definitions based on our over 20 years of experience in systems engineering, and has responded by providing a complete MDD environment with all it’s added benefits to SysML.

I-Logix will be conducting a web seminar about the latest version of SysML and how using Rhapsody’s key enabling MDD technologies brings added value:

  • Explanation of SysML and the 8 key diagrams contained in the specification
    • Requirements and Use Case diagrams for capturing, tracing and elaborating systems requirements
    • Block diagrams for defining the context and structure of the system
    • Statecharts, Activity and Sequence diagrams for describing the behavior and algorithms of the system
    • Parametric diagram to visualize constraints place on the system
  • Overview of Rhapsody’s Key Enabling Technology
    • SysML and UML 2.0 Integrated Requirements and Design modeling environment which enables clear, formal and non-ambiguous communication of the system to all stakeholders in the project.
    • Full lifecycle traceability and analysis to quickly manage and organize changing requirements and their impact on the design and architecture.
    • Customizable automatic documentation that allows you to produce System documentation quickly and efficiently
    • Full Model Simulation and Execution to verify systems designs are functionally correct upfront and satisfy requirements, thus ensuring costly re-engineering activities are minimized.
