This methodology aims at covering IR/RV sign-off with special emphasis on Rampup Analysis. It suggests some extra checks to help the designer catch the outliers which are overlooked in traditional methodology, thereby, signing-off the Power Integrity stage confidently. The methodology can be divided into three section: 1. Holistic Rampup Analysis accounting Noise Coupling & contribution of MiM [metal-insulator-metal] Cap 2. Rampup Analysis of Memories when only Rampup PWL is available 3. Ensuring Good Coverage of violators with Timing Window lying outside the simulation period.
