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 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).
