Modelling · SysML and UML
Model systems and software in SysML and UML, simulate designs early and generate code from the model.
RhapsodyIBM Engineering Rhapsody, formerly IBM Rational Rhapsody, is a model-based systems engineering (MBSE) and software design tool built on SysML and UML. Teams model requirements, architecture and behaviour, simulate designs and generate code.
Editions cover systems engineers, software designers and embedded developers. Rhapsody Developer generates production code in C, C++, Java and Ada, including MISRA‑C and MISRA‑C++.
Rhapsody supports AUTOSAR and defence frameworks such as DoDAF, MODAF, UPDM and UAF, and links models to IBM Engineering Requirements Management DOORS Next, IBM Engineering Test Management and IBM Engineering Workflow Management.
Rhapsody Designer runs models as prototypes, so you can validate requirements, architecture and behaviour before hardware or code exist. Rhapsody shares models with MathWorks Simulink, and reverse engineering brings in existing code. Add-ons cover automotive, aerospace and defence, transportation, electronics and medical.

Capabilities
Rhapsody Designer runs models as prototypes, so you validate requirements, architecture and behaviour before hardware or code exist. Errors found here cost a fraction of errors found in integration. Validate that the architecture supports the allocated functions before you hand off to development.

Analyse and elaborate requirements, make trade-offs with parametric evaluations.

Services
Architect for Systems Engineers covers SysML modelling and documents. Designer for Systems Engineers adds simulation and execution. Architect for Software covers UML and code frames, and Developer adds full code generation for C, C++, Java and Ada. We match editions to roles.
Floating licences suit most modelling teams. IBM tokens make sense when the same people also use DOORS Next, Test Management or Workflow Management. We size the mix from your user list.
We test your models, profiles and plug-ins on Rhapsody 10.0.2 first, then upgrade project by project. Rhapsody 10 changed the user interface, so we plan a short training for modellers.
Through OSLC links, set up in a lifecycle project or global configuration. Model elements satisfy requirements and the links show in both tools.
IBM Rhapsody Systems Engineering is IBM’s web-based SysML v2 tool. SysML v1 models from Rhapsody can be reused and migrated there.
Yes. Rhapsody shares models with Simulink, and the Rhapsody Automotive add-on (formerly the AUTOSAR extension) covers AUTOSAR workflows.
