WebJan 13, 2024 · The Dynamic Part Average Test, or DPA, is a semiconductor testing method that helps yield managers monitor process variations in order to improve yields. By tracking the average performance of a group of parts over time, DPA can help identify process changes that may be causing yield loss. Additionally, DPA can be used to … WebIn this paper we demonstrate with industrial data the application of Dynamic Part Average Testing (DPAT) at the final testing stage in order to improve the analog fault coverage of a mixed-signal automotive product. Simulation results on an industrial circuit indicate an analog fault coverage improvement from 31.3 % to 82.7 %.
