Refinement of Z specifications using reusable software components in Ada

Abstract

A method of refining 2 specifications into Ada using reusable software components is presented. Software oomponents are written to model the data structures supported by Z, such as sets and functions, enabling the data model of the abstract specification to be implemented directly. The operations of the specification are then implemented from their predicates using the operations of the Z software components. The method is illustrated using a simple specification.
