About

Astah SysML is a SysML v1 modeling tool for systems engineering and model-based systems engineering (MBSE), developed by Change Vision, Inc. It supports block definition, internal block, requirement, parametric, use case, state machine, activity, and sequence diagrams, plus requirement tables and mind maps. Designs are stored as models, so a change to a block or requirement is reflected in every diagram that uses it. Profiles, XMI import/export, and data exchange with Cameo Systems Modeler are supported. AI Chat Copilot works with your own API key for OpenAI, Azure OpenAI, Claude, Gemini, or an OpenAI-compatible service, and a local MCP server lets external AI agents work with your models. Astah SysML runs on Windows and macOS. Simulation is not included. A 20-day free trial is available. For SysML v2, Change Vision offers separate products that run as Visual Studio Code extensions: SysMLv2 Editor and SysMLv2 Modeler (early access).

About

Go beyond math-based modeling with a complete RF-aware design workflow, plus decades of Keysight measurement science in RF instrumentation, ready for any system architect. PathWave System Design offers the most advanced prototyping and design platform for complex RF systems with faster simulation speed, near-circuit fidelity, libraries for radar, electronic warfare, satellite, 5G, and WiFi, plus enterprise integration with numerous partners. Statistical models for propagation and channels can only take your system designs so far. Dynamic kinematic modeling for radar, electronic warfare, satellite, 5G, and automotive are all possible with connections to tools such as STK by AGI, an Ansys Company. Designers of advanced cellular systems need trusted reference libraries that are based on Keysight measurement science. Researchers exploring the next generation of communications signals need a flexible platform for physical layer development and testing.
