Towards a formal semantics for an integrated SA/RT and Z specification language

D. Scholz, Carsta Petersohn

Abstract

On the one hand we consider widely used structured analysis and real-time methods (SA/RT). Their specifications are intuitively readable but often semi-formal. On the other hand we consider the formal specification language Z. Using Z for the specification of data and data processing leads already to an improvement of SA/RT methods. In this paper, we extend this integration by new features. Moreover, we give the main ideas for a formal semantics which model the dynamic behavior of the system. This semantics adopts the main principles of synchronous languages. This is illustrated by a simplified version of the game PACMAN.
