Model-based System Development : Requirements Capture and System Design with Rational Statemate : Architectural System Approach

Architectural System Approach

The classical functional top-down approach, outlined in the previous section, is based on the assumption that the system is being designed from scratch with no legacy influences and with complete design control over the partitioning of functionality.

In practice, many applications require the design of additional system or sub-system functions embedded within an existing architecture. This places constraints on the designer, which need to be fully understood before the actual design can take place.

In the following sections, an equipment-related generic architectural system approach will be presented.
