Ansys SCADE Architect

SCADE Architect is part of the Ansys Embedded Software family of products, which gives you a design environment for systems with high dependability requirements. It provides full support of industrial systems engineering processes, such as ARP 4754A, ISO 26262 and EN 50126.

This product features functional and architectural system modeling and verification in a SysML-based environment. It provides a strong foundation to deploy model-based systems engineering (MBSE) processes and best practices. A key feature is the capability to generate consistent and comprehensive interface control documents (ICD).

SCADE Architect has been specifically developed for systems engineers; the underlying SysML™ technology is hidden, making modeling more user-friendly and intuitive than standard SysML tools or plain databases.

By using SCADE Architect in conjunction with other Ansys SCADE tools, system and software engineers can work within the same framework. Developers can quickly synchronize the system model and the software subsystem components, ensuring consistency of the software architecture and modeling efficiency — for instance, for the management of I/O definitions. Delivered with SCADE Suite, SCADE Architect provides an integrated software engineering solution combining software architecture and software design in a single, comprehensive user interface.
