Modelio SA - SysML

Dedicated to system architects working on SysML modeling,
UML/BPMN modeling and requirement analysis

Key Features

Modelio SA - SysML is designed to increase efficiency and improve productivity when defining system architecture and producing documentation.


System engineering

Modelio SA - SysML enables architects to formalize their functional system specifications with SysML, a simple and powerful language for system engineering.

Modelio SA - SySML fully supports SysML diagrams and provides many extras to make functional specification formal and unambiguous.

SysML modeling

SysML modeling

Modelio SA - SysML supports system architecture and functional specification modeling using SysML. In this product, SysML is seamlessly integrated with UML and requirements management.

The full range of SysML diagrams is supported, from block diagrams to internal and parametric diagrams. Each diagram provides a dedicated user interface that guides you through modeling activities.


UML integration

Modelio SA - SysML combines SysML with UML and BPMN diagrams to provide all the details necessary for system specification.

Modelio SA - SysML provides full support of UML2 and BPMN 2. Dedicated diagrams are included to specify use cases, classes, state machines, sequences, activities and processes, with all aspects managed in one single model.

Requirement modeling

Requirement modeling

SysML provides diagrams to model requirements. With the dedicated Analyst module, architects can then organize requirements using groups, hierarchy and dependencies, and edit their properties using either the built-in spreadsheet editor or MS Excel™.

Architects can assign model elements to requirements for traceability and impact analysis, and integrate diagrams, descriptions and matrices in project documentation such as SRS, IRS and SDD.

The Analyst module can be used in conjunction with Rational Doors™, or coupled to other tools if necessary.


Project documentation

Models and diagrams are used to document architecture decisions, so why not generate parts of these documents from UML?

Modelio SA - SysML provides templates for diagram books, reference documentation, specifications and traceability matrices. It supports the use of existing templates "as is" and also allows them to be adapted to specific project documentation procedures. Generated documents (in HTML, MS-Word or LibreOffice format) can be integrated into SDD, SRS and IRS.

Rich text editor

Integrated documentation capture

Modelio's support of rich text edition means that you can document any model element or diagram using your favorite editor (MS-Word, LibreOffice, ...), which is integrated with Modelio. This feature provides you with a unique means of combining models and documentation to support your analysis work.

Graphical link editor/Impact analysis

Modelio provides a graphical link editor that displays different types of links (for example, traceability links), enabling you to browse the entire model through its links.

Traceability management and multi-dimensional browsing in complex models are features which are particularly useful for system engineering.

The Modelio link editor also supports impact analysis, by providing links arriving from the opposite direction and arriving at a given element (for example, who implements such and such a requirement?).

Embedded systems

Embedded systems

OMG MARTE is a UML language for the system engineering of real-time and embedded systems. It covers a wide range of systems from automotive and aerospace to systems-on-chip. The MARTE Designer module enables architects to combine SysML, UML and MARTE within a single model.
