Optimizing Test To Enable Diagnosis-Driven Yield Analysis


Using diagnosis-driven yield analysis, companies have decreased their time to yield, managed manufacturing excursions and recovered yield caused by systematic defects. Dramatic time savings and yield gains have been proven using these methods. Companies must plan ahead to take advantage of diagnosis-driven yield analysis. The planning needs to include how and what patterns to generate during AT... » read more

LP Test


By Luke Lang Last month, we discussed testing a portion of a chip at a time to reduce overall power dissipation during test. However, this does not address local power dissipation hotspots that can cause excessive IR drop. These hotspots can occur in regions where many nets are switching at the same time. Typically, a chip’s power grid is designed to meet IR drop specification in the func... » read more
