Abstract
In random defect yield simulation, a specific defect size interacts with a specific physical design and has a calculated probability of failure associated with it. The failure model is in terms of probability of failure. It provides a solution to the random defect yield simulation problem of chips with a built-in redundancy scheme. The solution first defines the independent failure modes of the chip with a built-in redundancy scheme and efficiently models each mode. Then, it may accumulate the respective probability of failures according to the chip's architecture.
