Description

20-sim is a comprehensive software tool designed for modeling and simulating mechatronic systems. The interface enables users to graphically input models, resembling the process of sketching an engineering diagram. Utilizing these models, one can assess and simulate the dynamics of complex multi-domain systems while also developing control strategies. Additionally, the software allows for the generation of C-code, which can be deployed on hardware to facilitate rapid prototyping and Hardware-in-the-Loop (HIL) simulations. 20-sim is equipped with features that streamline the modeling process, making it both fast and user-friendly. Users have the option to model using various methods, including equations, block diagrams, physics blocks, and bond graphs. To assist in constructing models, the 20-sim editor boasts an extensive library filled with building blocks and components, such as block diagrams and bond graphs, making it easier to create and analyze complex systems efficiently. Overall, this software package serves as a powerful tool for engineers seeking to innovate in the field of mechatronics.

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.
