Abstract

This paper describes the testability, debuggability, and manufacturability features of the UltraSPARC-I microprocessor. Due to the aggressive nature of this high performance design, these three areas needed to be addressed at the beginning of the project to ensure success. We present the goals and analysis that lead to our decisions as well as the actual features that were implemented. The features described in this paper have helped enormously in achieving the time-to-volume goals and hence the overall success of the product
