Abstract :
Presents a case study of a structured design for test (DFT) methodology that was formulated for a major system design project consisting of 11 complex ASICs. The methodology includes full scan for chip test, and an optimized boundary scan for board test. The paper discusses details of the ASIC designs and technology, the DFT methodology, the design of test logic, ATPG tool selection, development of in-house tools, and integration of DFT into the overall design flow. This project has demonstrated that DFT can be considered early in the design and integrated efficiently into the design flow.<>
