Cameo Systems Modeler Integrations

Astah SysML helps systems engineers capture requirements, structure, and behavior in SysML v1 without the weight of a large enterprise suite. Block definition and internal block diagrams, requirement diagrams and tables, parametric diagrams, and use case, state machine, activity, and sequence diagrams are all included, along with mind maps for early concept work. Each diagram is a view of one shared model, so updating a requirement or block keeps every related diagram in step. Assist functions such as double-click creation, creating multiple elements from text, and alignment guides reduce drawing time. Models can be exchanged through XMI and with Cameo Systems Modeler, and profiles let teams extend the language. For AI-assisted work, AI Chat Copilot connects to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key, and a local MCP server lets external AI agents read and work with your models. Astah SysML runs locally on Windows and macOS. It does not include simulation. Developer: Change Vision, Inc. Current version: 11.0 (March 2026).

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.

Requs Suite is a powerful toolset for software reliability and safety analysis, offering software reliability prediction, failure mode analysis (FMEA), sensitivity analysis, and reliability growth tracking. Requs AI Predict stands out with its machine learning model that predicts defect density before the code is even written, while also forecasting escaped defects, failure rates, MTBSF, and overall reliability. Its software FMEA tool intelligently evaluates design risks and integrates with MBSE tools, supporting international FMEA standards for both reliability and safety analyses. The suite also offers advanced sensitivity analysis for identifying key factors in defect reduction.
