About

AVSnap is easy to use and simple to learn. All of the features are at your fingertips. Need to conduct technical sales? No problem: get your diagrams ready in record time. Use manufacturer component libraries to zip you through a design process. No problem: use built-in GUI designer with simple to learn control code to make the system fully operational within hours. The power of AVSnap rests in its Library Editor. Draw your symbols, add snap points and adjust functionality. It takes a few simple steps to create a library component, but the dividends pay long after it is done. Once created, they can be re-used anywhere in the design. AVSnap is uniquely capable of controlling any controllable device. It can lower shades, adjust volume, switch video inputs, open garage door, adjust the temperature, detect the presence, send emails, communicate over TCP/IP, communicate via rs-232, and much more.

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.
