An intelligent software-integrated environment of IC test

The migration and simulation of IC test programs among the heterogeneous ATE systems are a very difficult task. An unifying IC test software-integrated environment from simulation to test for digital circuit has been developed. The environment, TeDS which is designed by using object-oriented paradigm, supports two kinds of CAD systems and three kinds of ATE (Automatic Test Equipment). The paper focuses on issues and techniques in developing TeDS based on object-oriented paradigm.
