We provide technical assistance and guidance to transform the architectural design process from one based on human evaluation to one based on automated analysis.

This analysis includes

  • validating system quality attributes early in the design phase
  • facilitating system integration
  • conducting impact and tradeoff analysis using architecture models

Architectural Model

Single Model Supporting Multiple Analyses

An architecture-centric, model-based approach supports multiple analysis, performed throughout the life cycle, on a single model.

The SEI uses the Architecture Analysis and Design Language (AADL) to document a system architecture and provide a platform for multiple analyses. AADL, an international industry standard, supports multiple analyses from a single architectural model, enables modeling and analysis throughout the life cycle, and provides analysis of runtime behavior such as availability, performance, and security.

Through its XML/XMI interchange format, AADL supports model interchange and tool chaining. And, the SEI offers the freely available Open Source AADL Tool Environment (OSATE) set of analysis plug-ins that includes

  • a syntax-sensitive text editor, with integrated error reporting
  • a parser and semantic checker for textual AADL with conversion into AADL XML
  • an unparser for AADL XML to textual AADL conversion
  • support for multi-enterprise development through a version control system interface

AADL also can be used with
