Need for dynamic IR drop analysis at floor and power planning stages?

Here is a question for all the power grid designers out there: Do you see the need to do quick early dynamic rail analysis during floor and power planning stages of our design? With introduction of the Cadence Encounter Power System today, Cadence First Encounter and SoC Encounter users will have access to the Encounter Power System signoff engines during floor or power planning design stages at no additional cost.

This analysis, called Early Rail Analysis (ERA), allows correct-by-construction power grid design. Designers can quickly draw current regions, leverage the Encounter Power System power engine if needed, use fast extraction and virtual connectivity to quickly analyze optimal location for their IOs, blocks and power grid mesh.

The consistency of the engines during ERA, optimization and signoff shortens design cycles and avoids last minute signoff surprises ERA currently allows only static power and IR drop analysis, but a few customers have asked us for ability to do dynamic ERA as well.

This would allow study of the grid at floor and power planning stages using block current signature and capacitance as inputs. I am very curious to know what other designers think about this feature.

Do you see a significant use for it?
