Today's SoC designs contain many types of circuitry, each with various test types. This article revisits the classic test escape models and highlights their limitations in a test environment with different types of circuits and different test types w

The quantity and complexity of data generated at each test manufacturing step can be daunting. This article, which emerged from a tutorial presented at ITC 2008, explains the application of statistics to help process that data and provides examples o

The expanded role of test demands a significant change in mind-set of nearly every engineer involved in the screening of semiconductor products. The issues to consider range from DFT and ATE requirements, to the design and optimization of test patter

Structured delay tests have been around for years, but how effectively do they identify defective silicon, even at reduced frequency? How much overkill is associated with their use? The authors present data from industrial circuits aimed at these and

To screen defective dies, I/sub DDQ/ tests require a reliable estimate of each die's defect-free measurement. The nearest-neighbor residual (NNR) method provides a straightforward, data-driven estimate of test measurements for improved identification

Barriers to technology scaling, such as leakage and parameter variations, challenge the effectiveness of current-based test techniques. This correlative multiparameter test approach improves current testing sensitivity, exploiting dependencies of tra

As process technologies continue to scale, the effects of temperature can no longer be neglected. High on-chip temperature causes frequency degradation, increases wasteful leakage power, and lowers device reliability. Therefore, managing on-chip temp

This paper introduces an adaptive test method to dynamically control test flow and test contents with continuous per die updates of test fail rates. The method employs Bayesian statistics to model a separate fail rate for each test. Test reordering a

This paper presents a method using only the rank of the measurements to separate a part's elevated response to parametric tests from its non-elevated response. The effectiveness of the proposed method is verified on the 130nm ASIC. Good die responses

This paper examines fault-tolerant DfT (Design for Test) circuits as an effective approach for improved reliability and lower defective parts per million (DPPM). The paper provides a comprehensive examination of one alternative, quadded gate, inter-l
