Nanometer Technology Designs

Beschreibung

While adopting newer, better fabrication technologies provides higher integration and enhances performance, it also increases the types of manufacturing defects. With design size in millions of gates and working frequency in GHz, timing-related defects have become a high proportion of the total chip defects. For nanometer technology designs, the traditional test methods cannot ensure a high quality level of chips, and at-speed tests using path and transition delay fault model have become a requirement in technologies below 180nm. Nanometer Technology Designs: High-Quality Delay Tests discusses these challenges in detail and proposes new techniques and methodologies to improve the overall quality of the delay test for nanotechnology designs. Topics covered include: At-speed test challenges for nanotechnology Low-cost tester-friendly design-for-test techniques Improving test quality of current at-speed test methods Functionally un-testable fault list generation and avoidance Timing-based ATPG for screening small delay faults Faster-than-at-speed test considering power supply noise Power supply noise tolerant at-speed test pattern generation and application Solutions for dealing with crosstalk and signal integrity issues Nanometer Technology Designs: High-Quality Delay Tests is a reference for practicing engineers and researchers in both industry and academia who are interested in learning about and implementing the most-advanced methods in nanometer delay testing.

Adopting new fabrication technologies not only provides higher integration and enhances performance, but also increases the types of manufacturing defects. With design size in millions of gates and working frequency in GHz timing-related defects havv become a high proportion of the total chip defects. For nanometer technology designs, the stuck-at fault test alone cannot ensure a high quality level of chips. At-speed tests using the transition fault model has become a requirement in technologies below 180nm.

Traditional at-speed test methods cannot guarantee high quality test results as they face many new challenges. Supply noise (including IR-drop, ground bounce, and Ldi/dt) effects on chip performance, high test pattern volume, low fault/defect coverage, small delay defect test pattern generation, high cost of test implementation and application, and utilizing low-cost testers are among these challenges. This book discusses these challenges in detail and proposes new techniques and methodologies to improve the overall quality of the transition fault test.
