Abstract:
1. A method, in a data processing system, for characterizing variability in manufacturing an integrated circuit design, the method comprising: fabricating one or more pattern samples, wherein each of the one or more pattern samples is an integrated circuit having a predetermined pattern and a plurality of current-voltage sensors; performing measurements across the plurality of current-voltage sensors; generating one or more data models based on the measurements; receiving, by the data processing system, an integrated circuit design to be analyzed; applying, by the data processing system, the one or more data models to the integrated circuit design to identify potential problems due to variability; generating, by the data processing system, variability analysis results based on application of the one or more data models to the integrated circuit design; and presenting, by the data processing system, the variability analysis results.
