ALEX: A Conversational, Hierarchical Logic Design System

Abstract

A fresh look at the technical problems of present-day logic design and at the principal activities of the logic designer resulted in a system for hierarchical logic design. It is supported by a novel, high-level graphic language to describe the connections between logical devices. A major concern was to ensure that processes invoked by a user while designing, modifying and testing logic normally require only a few seconds or, on rare occasions, a few minutes to execute.
