SOC Design for Testability (DFT)
This chapter describes requirement for testability, the design for testability (DFT) of SOC. It explains the methodology widely followed for SOC DFT and the automatic test pattern generation (ATPG) techniques. It covers the major challenges faced during SOC design in the context of DFT. This chapter introduces the concept of compression and need for test optimization to reduce ATE test times and its impact on economics of SOC.
