What is Vitech CORE?

Since its launch in 1993, CORE has supported countless projects and aided numerous systems engineers. From the beginning, it has been a proponent of model-based systems engineering principles. By utilizing a systems metamodel combined with powerful view generators, CORE allows for the instant creation of diagrams while maintaining consistency, thereby contributing to a wealth of successful systems engineering projects worldwide. While GENESYS has become the choice for many organizations today, Vitech remains dedicated to those who still rely on CORE for their systems engineering needs. Similarly to how managing interfaces in system design is vital for success, the careful handling of data relationships is equally essential in meeting project goals. This comprehensive approach to systems engineering not only boosts efficiency but also catalyzes innovation across the industry. As the landscape of systems engineering continues to evolve, the enduring relevance of CORE highlights its foundational role in shaping best practices.

What is Astah SysML?

Astah SysML is a desktop SysML v1 modeling application from Change Vision, Inc. for organizations adopting model-based systems engineering (MBSE). It gives engineering teams the core SysML diagrams, including requirement, block, parametric, and behavior diagrams, in a tool that new users can learn quickly. Because designs are stored as models, an update made in one place carries through to every related diagram, which keeps system documentation consistent as a project evolves. Existing models can be exchanged through XMI and with Cameo Systems Modeler. Version 11.0 includes AI Chat Copilot, which runs on your organization's own API key for OpenAI, Azure OpenAI, Claude, or Gemini, or for an OpenAI-compatible service, and local MCP server integration for connecting AI agents. Licensing is available as a 1-year license ($140) or a 1-year floating license ($270). Astah SysML runs on Windows and macOS, and a 20-day free trial is available.
