About

Astah SysML is a SysML v1 modeling tool for systems engineering and model-based systems engineering (MBSE), developed by Change Vision, Inc. It supports block definition, internal block, requirement, parametric, use case, state machine, activity, and sequence diagrams, plus requirement tables and mind maps. Designs are stored as models, so a change to a block or requirement is reflected in every diagram that uses it. Profiles, XMI import/export, and data exchange with Cameo Systems Modeler are supported. AI Chat Copilot works with your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service, and a local MCP server lets external AI agents work with your models. Astah SysML runs on Windows and macOS. Simulation is not included. A 20-day free trial is available. For SysML v2, Change Vision offers separate products that run as Visual Studio Code extensions: SysMLv2 Editor and SysMLv2 Modeler (early access).

About

IBM® Engineering Systems Design Rhapsody® (Rational Rhapsody) and its family of products offers a proven solution for modeling and systems design activities that allows you to manage the complexity many organizations face with product and systems development. Rhapsody is part of the IBM Engineering portfolio that provides a collaborative design development, and test environment for systems engineers that supports UML, SysML, UAF and AUTOSAR. The solution also allows for control of defense frameworks (DoDAF, MODAF and UPDM) and helps accelerate industry standards such as DO-178, DO-178B/C and ISO 26262. Get continuous validation through rapid simulation, prototyping and execution to address errors earlier when they are less costly to fix. Use automatic consistency checking to enhance agility and improve reuse with collaboration to reduce both recurring and non-recurring costs.
