摘要
According to one exemplary embodiment, a computer implemented method for detecting multiple failure modes in a set of electromigration failure data points includes sorting the data points by time to failure and dividing the data points to form first and second groups of data points to determine a first combination of first and second seed groups of data points providing an initial highest weighted R-square. The method further includes defining an intermediate group of data points shared between the first and second seed groups of data points and grouping the intermediate group of data points with the first and second seed groups of data points to determine a second combination of the first and second seed groups of data points providing a final highest weighted R-square. The initial highest weighted R-square is then compared to the final highest weighted R-square.
