Architecture-Centric Engineering is the discipline of using architecture as the focal point for performing ongoing analyses to gain increasing levels of confidence that systems will support their missions.

The ACE Unit in RTSS develops principles, methods, foundations, techniques, tools, and materials for

• architecture methods and underlying technology
• architecture competence
• architecture evolution
• dependability, performance, and security analyses
• static analysis and model checking
• code analysis
• multi-core
• architecture for ULS systems
• computational mechanism design
