Description
Astah SysML helps systems engineers capture requirements, structure, and behavior in SysML v1 without the weight of a large enterprise suite. Block definition and internal block diagrams, requirement diagrams and tables, parametric diagrams, and use case, state machine, activity, and sequence diagrams are all included, along with mind maps for early concept work.
Each diagram is a view of one shared model, so updating a requirement or block keeps every related diagram in step. Assist functions such as double-click creation, creating multiple elements from text, and alignment guides reduce drawing time. Models can be exchanged through XMI and with Cameo Systems Modeler, and profiles let teams extend the language.
For AI-assisted work, AI Chat Copilot connects to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key, and a local MCP server lets external AI agents read and work with your models.
Astah SysML runs locally on Windows and macOS. It does not include simulation. Developer: Change Vision, Inc. Current version: 11.0 (March 2026).
Description
System Composer™ facilitates the detailed specification and evaluation of architectures within the realm of model-based systems engineering and software architecture modeling. By utilizing System Composer, users can effectively allocate requirements while enhancing an architecture model, which can subsequently be designed and tested in Simulink®. Users have the flexibility to create architecture models composed of components and interfaces either from scratch, by importing from other tools, or by leveraging the architectural elements already present in Simulink designs. Furthermore, it allows for the representation of a system through various architecture models, enabling the establishment of direct connections between them through model-to-model allocations. Behavioral aspects can be documented using sequence diagrams, state charts, or Simulink models, providing a comprehensive overview of system dynamics. Additionally, you can specify and simulate the order of execution for component functions, and even generate code from your software architecture models utilizing tools like Simulink and Embedded Coder®. This seamless integration ensures a robust framework for developing complex systems efficiently.
