CA resistance variability prediction methodology

摘要

A methodology for obtaining improved prediction of CA resistance in electronic circuits and, particularly, an improved CA resistance model adapted to capture larger than anticipated “out of spec” regime. In one embodiment, a novel bucketization scheme is implemented that is codified to provide a circuit designer with considerably better design options for handling large CA variability as seen through the design manual. The tools developed for modeling the impact of CA variable resistance phenomena provide developers with a resistance model, such as conventionally known, modified with a new CA model Basis including a novel CA intrinsic resistance model, and, a novel CA layout bucketization model.
