Abstract :
This paper presents a new, layout-based approach to board-level shorts diagnosis for bussed drivers, with the goal of early repair of interconnect shorts so as to minimize (a) fault masking during opens testing and (b) driver abuse. This approach leads to an early diagnosis of more than 96% of shorts and simplifies the subsequent rest for opens considerably. Besides, this approach improves the production yield and field survivability of boards.
