Abstract :
Achieving 100 DPPM on today´s complex ASIC is a realistic but difficult proposition. This work deals in achieving 100 DPPM without functional testing and the advances that are needed to meet these challenges. Structural based test with proper design-for-test (DFT) and scan based testing. The measuring stick for DFT was the stuck-at fault (SAF) test coverage a design could obtain with scan based test. Very deep sub-micron (VDSM) and nanometric designs require additional structural testing such as transition delay fault (TDF) testing. Defect based test methods that focus on outlier identification and removal from test data sets are a critical component in achieving 100 DPPM. Finally, adaptive testing ensure consistent quality and reliability results over the lifetime of the device.
