The power of software modeling.
Astah’s modeling tools allow you to visualize the essence of your ideas and software designs. Quickly and effortlessly build diagrams that create a clear understanding among teams.
Build UML, ER diagrams, Data Flow Diagrams, Flowcharts, mind maps and more in the most powerful modeling software for everyone from students to enterprise teams.
Design, Verify and Validate
Astah System Safety is a modeling tool for safety-critical systems to support system architecture modeling, system safety assessment and analysis using STAMP/STPA, SysML, SCDL and GSN.
This 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).
SysML Diagrams
Astah System Safety’s SysML support is more advanced than what “Astah SysML” offers including the abilities such as merge and comparing project files, XMI import/export, and integration with Cameo Systems Modeler by Dassault Systèmes.
STAMP / STPA
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.
SCDL
SCDL (Safety Concept Description Language) is a language for safety architecture designs defined by Safety Concept Notation Study Group.
GSN (Goal Structuring Notation)
You can visualize the safety arguments using Goal Structuring Notation and also D-Case that effectively works for Consensus Building and Accountability Achievement.
