Let us start this chapter by recalling that our aim is to develop a design methodol-

meet these requirements by a top-down process of subdivision of the requirements
into smaller sets. e end result of this process of design in the functional domain
is a set of interacting functional elements for which the transition into the physi-

process invol ...
