Modeling Systems in Enterprise Architect

Using SysML in Enterprise Architect, the process of developing a model to design or investigate a system is quick and easy, but at the same time versatile and flexible with a full implementation of the SysML specification. An outline of the stages of the process, and the steps for the initial stage, are provided here. Work through these steps to create a model to help engineer your system.

Create a Systems Engineering Model Framework

Follow the step-by-step guide in the table Create a Systems Engineering Model from a Template at the end of this topic.

Create a Requirement Model to Define the System's Requirements and Expectations

The SysML Requirement Model provides the system requirements, the expected abstract behavior, and the operating constraints that the designed system must conform to.

See the SysML Requirements Modeling Help topic.

Create an Operational Domain Model

The Operational Domain Model describes the environment that the system operates within, and the entities it interacts with.

Design the System's Composition Using SysML Blocks and Parts

Create Constraint Models

Constraint models describe the system's operating characteristics, using Parametric models.

Simulate the Parametric Models

Simulating the Parametric models helps to verify their correctness and obtain the desired characteristics.

SysML Parametric models support the engineering analysis of critical system parameters, including the evaluation of key metrics such as performance, reliability and other physical characteristics.

See the Parametric Simulation Help topic.

Implement the Embedded Software

You implement the embedded software using UML Classes and Behavioral models.

Create a Library of Reusable SysML Blocks

The reusable SysML Blocks represent subsystems that can be reused on other projects, and other common type definitions.
