Research on the characteristics theory of reverse SoC TAM design based on dual-balanced strategy

The paper presents a reverse SoC TAM design based dual-balanced strategy, which is on the basis of IEEE1500. Firstly test scheduling is executed according to the conceptual TAM architecture that is physically realizable, and then the real TAM architecture can be reversely established according to the test scheduling result. Since the test scheduling is not limited by TAM architecture, the test scheduling optimization can involve both top level and IP level and obtain the cross-level combined optimization between these two levels. The experimental results on the ITCpsila02 show the better availability and reliability and the performance improvement on test time of the proposed method, compared with several other representative approaches. Particularly, the method of this paper is based on the practical test cost, thus is of greatly practical value.
