Modern systems, from automobiles, consumer electronics, to network-centric defense systems are becoming more complex and increasingly contain larger proportions of software. These changes drive the need for a formal modeling language for systems and improved methods of communication between system and software engineers. This is what OMG SysML^TM is all about.

What is OMG SysML^TM?

SysML is a graphical modeling language which is based on the OMG’s Unified Modeling Language (UML). SysML supports modeling of a broad range of systems including hardware, software, data, personnel, procedures and facilities. SysML is a key enabler of Model-Driven Systems Engineering and is supported by the International Council on Systems Engineering (INCOSE).

What is the EmbeddedPlus SysML Toolkit?

An add-in product to the IBM RSDP, it provides SysML language support and related features to IBM Rational Software Modeler/Architect (RSM/RSA) and Rational Systems Developer (RSD). This combination provides a complete solution for systems and software engineers from requirements through to modeling and simulation in one working environment, including integrations with ClearCase and ClearQuest.

What are the benefits of using SysML?

• SysML improves communication by providing a formal language for sharing system information to all project stakeholders. Based on UML, SysML ensures the flow-down from systems engineering to software engineering is more accurate.
• SysML’s requirement modeling support provides the ability to assess the impact of changing requirements to a system’s architecture.
• SysML is a precise language, including support for constraints and parametric analysis which allows models to be analyzed and simulated, greatly improving the value of system model compared to textual system descriptions.
• SysML is an open standard and supports XMI and ISO 10303-303 (AP233) allowing for information interchange to other systems engineering tools such as CAD, electrical and engineering-analysis tools.

What are the benefits of using the EmbeddedPlus SysML Toolkit?

• The SysML Toolkit plugs directly into IBM Rational’s Eclipse-based modeling and development environment, allowing the sharing of model artifacts between system and software engineers, all from within a common tooling environment.
• Provides SysML requirements modeling capabilities and integrates with traditional requirements management tools such as Telelogic DOORS® (via EmbeddedPlus DoorKeeper) and IBM Rational RequisitePro to ensure traceability.
• SysML models can be statically analyzed using model validation including support for OCL. SysML Models can also be executed via the EmbeddedPlus Simulation Toolkit.
• The SysML Toolkit and IBM Rational’s supporting modeling platform are based on open standards including the open-source Eclipse plug-in architecture, Eclipse’s UML2 reference implementation, and supporting XMI model storage format. Based on Eclipse, you can easily extend the tooling by creating custom plug-ins or by purchasing commercial plug-ins to supplement your tooling environment.
• Leverage your investments in Rational Rose with no-cost trade up to Rational’s Modeling platform. Rose models are easily imported and can be upgraded to support SysML with a single click.
