Patent ID: 8239814

Claim:
A method for predicting parameter drift in a system, the method comprising: recording a data set of parameter drifts over a period of time for each of a plurality of stress tests on the system at a corresponding plurality of stress levels; organizing each data set of the recorded parameter drifts as a plurality of parameter drift versus time plots; selecting a linear plot as a reference plot; time shifting the plots in relation to a reference plot by a time shift amount to form a single parameter drift plot, comprising: selecting the time shift amount by comparing each of the plurality of parameter drift versus time plots with the reference plot; time shifting the data sets for each of the plurality of stress tests by the time shift amount; replotting the time shifted data from all the test to create the single parameter drift plot; fitting a non-linear equation to the single parameter drift plot; and predicting an amount of parameter drift at a time beyond the period of time using the non-linear equation, wherein organizing each set of the recorded parameter drifts is performed in a log(y)-log(x) space; outputting interactively a plurality of simulation results on a display.
