WebAug 10, 2024 · There is a significant impact of low power design techniques and power constraints on the design-for-test (DFT) implementation and manufacturing test of ICs. 2a: Level-shifters used for signals that cross domains operating at different voltage levels. 2b: Isolation cells used to separate active logic from powered-down logic. WebDFT, Scan and ATPG. The chip manufacturing process is prone to defects and the defects are commonly referred as faults. A fault is testable if there exists a well-specified procedure to expose it in the actual silicon. To make the task of detecting as many faults as possible in a design, we need to add additional logic; Design for testability ...
