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/D-Case assurance cases, ASAM SCDL safety concepts, 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. Safety engineers in automotive, aerospace, railway, and embedded systems use it to build safety cases for standards such as ISO 26262. AI Chat Copilot and a local MCP server require your own API key from a supported AI service (OpenAI, Claude, Gemini, or an OpenAI-compatible endpoint). SysML models can be exchanged with Cameo Systems Modeler through XMI import and export. Runs on Windows and macOS. FTA, FMEA, and simulation are not included. A 40-day free trial is available.

About

Go beyond math-based modeling with a complete RF-aware design workflow, plus decades of Keysight measurement science in RF instrumentation, ready for any system architect. PathWave System Design offers the most advanced prototyping and design platform for complex RF systems with faster simulation speed, near-circuit fidelity, libraries for radar, electronic warfare, satellite, 5G, and WiFi, plus enterprise integration with numerous partners. Statistical models for propagation and channels can only take your system designs so far. Dynamic kinematic modeling for radar, electronic warfare, satellite, 5G, and automotive are all possible with connections to tools such as STK by AGI, an Ansys Company. Designers of advanced cellular systems need trusted reference libraries that are based on Keysight measurement science. Researchers exploring the next generation of communications signals need a flexible platform for physical layer development and testing.

Pricing

$550 per year
Annual license: $550 per user per year. Annual floating license: $1,050 per seat per year, with a self-hosted license server required. Per-seat floating prices decrease with larger packs (for example, $9,500 for 10 seats). Monthly licenses are not available.

For universities, the Faculty Site License ($900) covers Astah System Safety, Astah SysML, and Astah Professional for all faculty and students in a department.

A 40-day free trial is available. AI features (AI Chat Copilot and the local MCP server) require your own API key from a supported AI service, and API usage is billed separately by that provider.
