SigmaAV: High Global and Local Noise Coverage Solution for Power Integrity Signoff
DescriptionSigmaAV is a unique solution that provides complete power grid noise coverage for 100% of the instances in a design. This novel simulation technique uses comprehensive aggressor knowledge & local noise coverage from SigmaDVD technology (verified in the past) and global noise coverage from Vectorless analysis (widely accepted industry standard for time-based IR analysis).It's an efficient technique to compute the worst case, but statistically relevant, voltage drop for every instance. This analysis bridges the gap in power grid noise coverage observed in traditional methods, such as local noise coverage in Vectorless and global noise impact in SigmaDVD. With SigmaAV's comprehensive local and global noise coverage, we did voltage-annotated timing analysis to identify relevant timing paths. We quantified the hotspot coverage capabilities of SigmaAV through heatmap comparisons and its timing path coverage through scatterplots. In this presentation, we will discuss the theory of SigmaAV and various conducted trials to compare SigmaAV with other available IR-Drop methods.
