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
Since its inception in 1993, CORE has been the backbone for thousands of projects and has assisted tens of thousands of systems engineers. From the outset, CORE has championed the principles of what we now recognize as model-based systems engineering. By leveraging a systems metamodel that integrates with robust view generators, it enables the on-demand production of diagrams while ensuring consistency, thus fostering a generation of successful systems engineering initiatives globally. Although GENESYS is the preferred option for many organizations in the current landscape, Vitech remains committed to supporting projects and clients who continue to depend on CORE for their systems engineering requirements. Just as defining and managing interfaces in system design is crucial for success, so too is the effective management of data interrelationships, which plays a pivotal role in achieving project objectives. This holistic approach to systems engineering not only enhances productivity but also drives innovation in the field.
