Power-Ground grid insertion

IR drop analysis in VLSI explained for physical design engineers: where supply and ground drop come from, static vs dynamic IR drop, vectorless and vector-based analysis, how IR drop affects setup and hold, and how to debug and fix hotspots, with illustrative examples, a flowchart and interview Q&As.

Backside power delivery moves the power grid below the transistors. What it changes in floorplanning, PDN, placement, CTS, routing, IR/EM and thermal signoff, with a practical checklist.
