About

Astah System Safety is a model-based safety analysis tool for safety-critical systems, developed by Change Vision, Inc. It combines SysML modeling with STAMP/STPA hazard analysis, GSN (Goal Structuring Notation) assurance cases, ASAM SCDL, and UAF in one tool. Safety analyses are linked to the system model, so control structures, hazards, and safety arguments stay traceable to requirements and architecture. It is used by safety engineers in automotive, aerospace, and embedded systems, including safety-case work for standards such as ISO 26262. 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 connects external AI agents to your models. Models can be exchanged through XMI and with Cameo Systems Modeler. Astah System Safety runs on Windows and macOS. FTA and FMEA are not included. A 40-day free trial is available.

Pros & Cons from Real Users

Pros

  • comprehensive but once you mater the art behind it you master the secrete of reliability, availability and maintainability

Cons

  • complex to learn though easy to master. However given enough time one can adapt properly and do great things. Therefore there is a need for the software developers to work on some complexities and make the software so user friendly
