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
Simcenter Embed is a Siemens block diagram and state chart environment designed for embedded firmware development and hardware-in-the-loop prototyping. It helps users build, simulate, test, and automatically generate code for embedded control systems. The software supports electric motor control, digital power design, and image and video processing with libraries and on-chip peripheral support. Simcenter Embed reduces manual coding by converting block diagrams and state charts into hardware-ready MCU code. Users can simulate controller and plant behavior, tune controllers offline, and use integrated HIL testing to debug and validate embedded systems on target hardware. With efficient ANSI C code generation, real-time monitoring, and support for popular microcontrollers, Simcenter Embed helps teams speed up embedded system development.

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.
