Description
Astah System Safety is a comprehensive tool designed for model-based safety analysis in critical systems, created by Change Vision, Inc. This innovative software integrates SysML modeling with STAMP/STPA hazard assessments, GSN (Goal Structuring Notation) assurance cases, ASAM SCDL, and UAF, all within a single platform.
By linking safety analyses directly to the system model, it ensures that control structures, hazards, and safety arguments remain traceable to both requirements and system architecture. This tool is particularly valuable for safety engineers working in sectors such as automotive, aerospace, and embedded systems, facilitating safety-case development in compliance with standards like ISO 26262.
Additionally, the AI Chat Copilot feature utilizes your own API key for various services, including OpenAI and Azure OpenAI, and connects to a local MCP server to integrate external AI agents with your models. Models can be easily shared using XMI format and with Cameo Systems Modeler for enhanced collaboration.
Astah System Safety is compatible with both Windows and macOS platforms, although it does not include Fault Tree Analysis (FTA) or Failure Mode and Effects Analysis (FMEA). A free trial period lasting 40 days allows potential users to explore its capabilities before committing to a purchase. Overall, this tool represents a significant advancement in ensuring the safety of complex systems.
Description
Deos™, developed by DDC-I, is a safety-critical real-time operating system (RTOS) that has been rigorously verified according to DO-178C/ED-12C Design Assurance Level A (DAL A) standards specifically for avionics applications. This RTOS supports ARINC 653 APEX and rate monotonic scheduling (RMS), and it is designed to meet the FACE Safety Base Profile requirements. Since its initial verification by Transport Canada in 1998, it has been a trusted solution in the aviation industry, with its certification allowing it to operate in tens of thousands of aircraft. Over the past two decades, Deos has adapted and evolved to incorporate new processors and features, demonstrating its flexibility and resilience. It has also undergone successful audits by a range of global certification authorities, including the FAA, ENAC, JAA, EASA, and CAAC, as well as by designated engineering representatives from various airframe and avionics suppliers, ensuring its continued compliance with industry standards. Its proven track record and ongoing development make it a pivotal component in modern aviation safety systems.
