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.

About

Coco by Qt is an end-to-end code coverage and test analysis tool built for teams developing desktop, embedded, and safety-critical software. It supports multiple languages—including C, C++, C#, QML, and Tcl—and provides detailed insight into code coverage across unit, integration, and system testing. Coco helps engineering and QA teams identify untested paths, redundant test cases, and hidden logic branches to improve software reliability and performance. Designed for compliance-driven industries, it generates audit-ready reports aligned with international standards like ISO 26262, DO-178C, and IEC 62304. Seamlessly integrating with CI/CD pipelines and IDEs such as Visual Studio, Eclipse, and Qt Creator, Coco streamlines test validation across toolchains and environments. With precision, automation, and compliance at its core, Coco enables faster releases without compromising quality or safety.
