Requirements Engineering

The IBM® Rational® Rhapsody® environment assists teams by helping them gain better understanding of the requirements by visualizing them using standard UML or SysML Requirements are stored in the model and relations to design elements and test cases can be created, helping to provide traceability information within the model. Information from requirements such as the id or specification can be automatically generated into the code using Rational Rhapsody Developer or Rational Rhapsody Architect for Software to enable traceability from requirements, design in the model and implementation in code. Export of model information to IBM® Rational® DOORS® and IBM® Rational® RequisitePro®, is included through the Rhapsody Gateway feature.

The IBM® Rational® Rhapsody® Tools And Utilities Add On includes advanced capabilities of the Rhapsody Gateway feature to help you benefit from a seamless bi-directional information exchange interface with third-party requirements management tools, including Rational DOORS and IBM Rational RequisitePro, and requirements authoring tools, including Microsoft® Word® — extending a complete traceability solution that assists developers to examine the upstream and downstream impact of requirements changes on any level in realtime.

The Rational Rhapsody Gateway traceability solution helps you with:

  • Automatic management of complex requirements scenarios for intuitive, understandable views of upstream and downstream impact
  • Accurate impact reports and requirements traceability matrices to help you meet the most strident industry safety standards
  • Operates with the most popular requirements management/authoring tools, including Microsoft Word, Microsoft® Excel®, Microsoft® PowerPoint®, PDF®, ASCII, Adobe® Acrobat® 6.0+, Rational DOORS, IBM Rational, IBM RequisitePro, Borland CalibreRM, , Mathworks Simulink.
  • Development flexibility using a bi-directional interface with third-party requirements management and authoring tools
  • Rapid monitoring of all levels of the workflow to help improve project management and efficiency

Tools and Utilities

The IBM® Rational® Rhapsody® solution offers you the flexibility to integrate design and development functions into one cohesive environment. By helping enable team collaboration, requirements traceability, design specifications reviews, automatic documentation generation and rapid prototyping of the system as it is being built, the Rhapsody solution helps improve quality, reduce time-to-market and increase productivity.

The IBM® Rational® Rhapsody® Tools And Utilities Add On provides additional capabilities to help software developers improve the software development lifecycle, from initial concept to the finished product.

  • Customizable documentation generation with Rhapsody ReporterPlus
  • Automate documentation generation meeting company or industry standards
  • Advanced requirements analysis and traceability capabilities with Rhapsody Gateway feature ( see Requirement Engineering tab)
  • Interchange model information using XMI for reuse between modeling tools
  • XMI support validated at least through OMG Model Interchange Working Group (MIWG) test case 2
  • Support for SOA design approach with generation and import of WSDL files
  • Specify net-centric systems at a high level of abstraction and refrain from low level implementation details.
  • Siemens Teamcenter Systems Engineering integration provides traceability from design environment to PLM

The Rational Rhapsody Tools and Utilities Add On provides advanced capabilities for design validation and debugging for the Rational Rhapsody Developer and Rational Rhapsody Designer for Systems Engineer editions:

  • Graphical panels with knobs, buttons, dials, and meters for creating a mock up for simulation
  • Automatically generate a web based interface for rapid prototyping when using Rational Rhapsody Developer or Rhapsody Designer for Systems Engineers
  • Co-simulation of the plant models and architecture developed in Rational Rhapsody to validate design

Validation and Testing

The IBM® Rational® Rhapsody® Designer for Systems Engineers solution helps expand traditional MDD to include model driven testing. This combination creates a new paradigm of embedded development, helping ensure that your system will have fewer defects and that you spend less time in the testing phase, assisting in reducing overall testing costs significantly.

Animation provided by Rational Rhapsody Designer for Systems Engineers helps design level debugging of the model as it is being built, so that you can eliminate defects early. With animation you have the ability to control the design as you would with a traditional debugger but at a higher level of abstraction. You are able to inject events, call operations, step through the model, see active state highlighted in statecharts, and automatically generate sequence diagrams created from the running the executable —indicating the level of collaboration being performed in the design. The sequence diagrams created can be compared with the expected behavior to validate proper design operation.

The IBM® Rational® Rhapsody® TestConductor Add On provides code-based test generation and validation suite for realtime embedded applications. The Rational Rhapsody TestConductor Add On automatically generates a test architecture, which is a graphical Unified Modeling Language (UML) model of a code-based test harness, for portions of the design that need to be tested to help eliminate manual steps.

Test cases are next defined in the context of the test architecture, and can be defined as code, flowchart, statechart or as a scenario. The test cases can be executed in unison or combined. Rational Rhapsody TestConductor drives inputs, monitors design responses and provides the results of the test, including model coverage information for each test case.

The Rational Rhapsody TestConductor Add On helps your process with:

  • Automated creation of test architecture
  • Defining tests graphically, using flowcharts, sequence diagrams, statecharts
  • Monitoring test results on embedded targets
  • Instantiating parameterized sequence diagram test cases including interaction operators and timing
  • Driving your design based on test cases while monitoring all interactions
  • Analyzing failure with color-coded sequence diagrams

  • Reporting solution to help improve model coverage

  • Traceability to requirements for test case coverage of requirements

  • Code coverage results for test executions with Rational Rhapsody Developer for C

  • Manage test cases using IBM Rational Quality Manager integration

For early prototyping and creation of visual mock ups of the product early in development, graphical panels found in the Rational Rhapsody Tools and Utilities Add On offers the ability to perform rapid prototyping using various widgets such as knobs, buttons and displays bound to the model so that designs are clearly communicated among your peers, management, and customers, helping save your time and effort as compared to doing this manually.
