This document describes a formalism that allows for the capture and analysis of very large, complex, computer-based, real time systems. The formalism covers all aspects of a system, including functional the functions a system performs and non-functional characteristics of system performance attributes. The current proposed formalism captures the system design in five different capture views Informational, Functional, Behavioral, Implementation, and Environmental. Each capture view explores different aspects of the system, and all five in total provide a more complete understanding of the system design. Although the ultimate goal is to capture all aspects of the system in the five views, it is understood that techniques for analyzing system attributes such as hard real-time, security, reliability, and dependability are very diverse and evolve rapidly. Hence, the captured information is expected to be extendible and customizable to fulfill the need of each individual project. An example of a passive submarine sonar system is used throughout the document to illustrate the various capture techniques.
