Integration of DFT into RASSP

This paper describes the integration of Design-ForTestibility (DFT) processes, tools, and methodologies into the RASSP System, which consists of the Design Environment and Enterprise System. The blueprint for the DFT developments is the DFT Methodology, which is highly automated, hierarchical, and spans the entire life cycle, contributing significantly to the RASSP goals of 4x improvement in cycle time, design quality, and life cycle costs. Key concepts of the DFT methodology are covered. A preferred testability architecture that encompasses embedded test resources (BIST), external test resources (ATE), and testbenches for design verification is described. Integration of the DFT methodology and testability architecture into the RASSP system is covered. The paper concludes with a discussion of the contribution of DFT to meeting the RASSP goals.
