Astah System Safety is a modeling tool for safety-critical systems to support system architecture modeling, system safety assessment and analysis by incorporating the following modeling languages and techniques in one tool:
– ASAM SCDL
Traceability is assured between models (e.g. requirements and solutions) and API enables the integration with other applications.
Astah System Safety is for the automotive domain industry with self-driving cars that work with SOTIF and ISO 26262, and aerospace, railways, defense, robotics and healthcare industries where the safety property is crucial and also who are interested in adopting Model-Based Systems Engineering(MBSE).

Astah System Safety Features
Astah System Safety offers intuitive user interface enables you to rapidly implement engineering activities allowing multi-viewpoint modeling for successful systems engineering and reduce the costs of backtracking in system developments.
Aside the ease of diagram creation, Astah System Safety offers Team Collaboration features, extensibility with API and free plug-ins and also XMI import/export abilities that enables you to load data that is created by other tools such as Cameo System Modeler.
STAMP (System-Theoretic Accident Model and Processes) is an accident causality model based on systems theory developed by Prof. Dr. Nancy Leveson at MIT and STPA (System-Theoretic Process Analysis) is a technique based on STAMP. Astah System Safety provides the following diagrams and tables for your STPA analysis process.
You can visualize the safety arguments using GSN (Goal Structuring Notation) and also D-Case that effectively works for consensus building and accountability achievement.

Integrate with SysML
Integrate with MindMap
Astah System Safety supports model conversion between GSN and other diagram types. For instance, you can convert SysML blocks to Solutions, requirements to goals. Hyperlinks are automatically added between models to assure the traceability.
