Bottom-up Composition and Verification of Embedded Software

Abstract

This paper proposes service-oriented composition and verification techniques for incrementally extracting high-level abstract behavior of unit components in a systematic manner. Proposed techniques include the definition for abstract component, which is a basic building-block of the abstraction process, an algorithm for port-based synchronized abstraction, and projection abstraction. A verification framework is developed using the proposed techniques and its efficiency is demonstrated through a case example.
