An Integrated Design for Testability and Automatic Test Pattern Generation System: An Overview

Abstract

A general overview on an Integrated Design for Testability and Automatic Test Pattern Generation System (IDAS) is given. The major components of IDAS include: heuristic controllability/observability (C/O) analysis, prediction of testing costs, tools for evaluation, display and improvement of testability, and C/O guided automatic test pattern generator. The IDAS system includes also the logic and concurrent fault simulator CADAT. A brief description of major components with a scenario how to use IDAS is given. Future research activities are discussed.
