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
With TPT you can test ECU software and embedded control systems in all development phases such as model-in-the-loop (MiL testing), software-in-the-loop (SiL testing), processor-in-the-loop (PiL testing), hardware-in-the-loop (HiL testing), ECU testing and vehicle testing.
Whether you create a simple module test or a complex system test, TPT provides unique features to create those tests intuitively and flexibly. Safety standard directives can be satisfied while testing with TPT up to the highest safety level. Relevant standards, such as ISO 26262, are well supported.
TPT supports all testing activities from test case design/generation, test execution, test assessment and reporting, as well as test management and requirements traceability. We designed TPT to be the best tool for testing signal-oriented systems. With TPT your test case design is very powerful, easy to handle and easy to maintain even for complex systems with large interfaces.
