• Block diagram creation. Astah SysML allows you to design block diagrams (Block Definition Diagrams and Internal Block Diagrams) to represent the structure of a system. These diagrams show system components, their properties, and the relationships between them, helping to visualize the system architecture.
• Requirements diagrams. The tool supports requirements diagrams to capture and organize system requirements. Users can link requirements to other model elements to track their fulfillment.
• Activity diagrams. Astah SysML includes the ability to create activity diagrams to model process flows and system behaviors. These diagrams are useful for representing algorithms and workflows.
• Sequence diagrams. It allows you to design sequence diagrams to visualize interactions between system components over time. This is essential for use case scenario analysis.
• State machine diagrams. The tool supports state machine diagrams to model the dynamic behavior of system components in response to events.
• Parametric modeling and analysis. Astah SysML allows creating parametric diagrams to model mathematical constraints and relationships between system parameters, facilitating quantitative analysis.
• Documentation generation. The tool can export models to formats such as PDF, HTML, or Word, enabling detailed technical documentation to be generated directly from the diagrams.
• Integration with other languages. Astah SysML supports integration with UML, allowing SysML and UML models to be combined within the same project.
• Team collaboration. Models can be shared and edited by multiple users, facilitating teamwork on complex projects.
• Model validation. Astah SysML includes tools for validating model consistency, detecting possible errors in relationships between elements.

Astah SysML was developed by the Japanese company Change Vision. The project began in 2006 as an extension of Astah Professional, a UML modeling tool. The software is written in Java, making it cross-platform and capable of running on Windows, macOS, and Linux. Over the years, Astah SysML has evolved to comply with the latest SysML standards, incorporating new features and performance improvements.
