PRODUCT OVERVIEW

What is IBM Engineering Rhapsody?

IBM Engineering Rhapsody (formerly known as IBM Rational Rhapsody) is a model-based systems engineering (MBSE) tool that lets systems and software teams design, simulate, and validate complex products using industry-standard notations: SysML, UML, and AUTOSAR.

It connects requirements, architecture, behavior, and code in a single graphical environment, giving engineering teams a living digital thread across the entire development lifecycle. Whether you're building safety-critical avionics, an autonomous vehicle platform, or an embedded real-time system, IBM Rhapsody provides the rigor and traceability your program demands.

As part of the IBM Engineering Lifecycle Management (ELM) suite, IBM Rhapsody integrates natively with DOORS Next, ETM, and EWM, therefore enabling end-to-end traceability from stakeholder requirements all the way to validated code.

Model-Based Development Environment

Create and manage graphical SysML and UML models that serve as the single source of truth for system architecture, behavior, and interfaces.

Ease-of-use-icon_SodiusWillert_100x100px_color

Simulation & Early Validation

Prototype and simulate system behavior at the design stage by catching requirement conflicts and design errors before a single line of code is written.

Production Code Generation

Generate production-ready C++, C, Java, and Ada code directly from your models including MISRA-C compliance, with full round-trip engineering support.

KEY CAPABILITIES

Capabilities that address the complexity of modern Systems Engineering

Capabilities that make IBM Rhapsody the right choice for teams designing complex, regulated, or safety-critical systems.
global-configurations-ibm-sytems-design-rhapsody-SodiusWillert-1

Model-based systems engineering

IBM Rhapsody is your environment for iterative requirements analysis and refinement, subsequent functional analysis and elaboration of processes and systems behavior, and, finally, architecture modeling. Validate and verify the evolving model early in the process through simulating model execution in IBM Rhapsody.

Reuse existing code

For reuse of existing code in your IBM Rhapsody project, import the code module into your Rhapsody model. The imported module is stored as an external element in IBM Rhapsody and can be integrated into your model and visualized.

Developing safety-critical systems

Use IBM Rhapsody to develop safety-critical systems compliant with respective standards. IBM Rhapsody comes with various profiles that include already many of the prerequisites needed for developing safety-critical systems. Integrate with IBM DOORS for end-to-end traceability and complement with SodiusWillert Embedded UML RXF-Cert to generate certifiable code.

Dynamic model-code associativity

Activate this function in bi-directional mode and every change you make to the model is reflected almost simultaneously in the corresponding source code. And, if you edit the code, the model is automatically updated accordingly. Thus, model and code are always in sync without you explicitly initiating code generation.

autosar-ibm-sytems-design-rhapsody-SodiusWillert-5

Implementing AUTOSAR components

The typical elements of AUTOSAR, such as software, electronic control units, etc., are already defined in the AUTOSAR profile in IBM Rhapsody. Develop AUTOSAR compliant components using this profile without in-depth AUTOSAR knowledge. IBM Rhapsody will automatically transform your AUTOSAR component model into a UML model.

BENEFITS

Why engineering teams choose IBM Rhapsody

From aerospace primes to automotive Tier-1 suppliers, why engineering organizations in regulated industries standardize on IBM Rhapsody as their systems design environment.

Check mark_color_59x59px
Detect and resolve errors earlier in the project

With IBM Rhapsody, you start validating your design in parallel to creating the model. Simulate model execution within IBM Rhapsody and explore model behavior to identify potential flaws or errors in the requirements or in your design already in this early stage of your project. Take corrective action early, when it is less expensive.

Check mark_color_59x59px
Compliance with safety standards made easier

IBM Rhapsody supports a range of standards for the development of safety-critical systems, e.g. DO-178, DO-178B/C, or ISO 26262 or MISRA-compliant source code generation. Adherence to these safety standards significantly reduces the manual documentation effort associated with regulatory and certification compliance.

Check mark_color_59x59px
Cut project lead time through standards support

IBM Rhapsody simplifies the use of commonly used standard frameworks and profiles, making it easier for less experienced developers to comply with the standards required in a project. For example, the AUTOSAR profile facilitates the modeling and development of AUTOSAR-compliant components, often a mandatory requirement in automotive industry projects.

Check mark_color_59x59px
Stay on target through bi-directional traceability

Link your model in IBM Rhapsody to the requirements in IBM DOORS Next or another requirements management tool. By establishing a connection between a requirement and the model element that implements that requirement, you gain clarity about the agreed project scope and the progress against that scope.

Accelerate from design to delivered code

With full application generation for C++, C, Java, and Ada, and round-trip synchronization between model and code, development cycles shorten and manual translation errors disappear.
