System-chip test strategies

摘要

A major challenge in realizing core-based system-chips is theadoption of adequate test and diagnosis strategies. This paperfocuses on the current industrial practices in test strategiesfor system-chips. It discusses the challenges in testingembedded cores, the testing requirements for individualcores, and their test access mechanisms. It also covers theintegrated test strategies for system-chips based on reusablecores. In addition to the state-of-the-art practices intestability schemes, this paper covers the currentstandardization efforts for embedded core test interfacemechanisms.
