Floorplan keepouts, guard rings, substrate control, and PV/DRC/LVS considerations for mixed-signal SoC integration.
Start with topic hubs to learn contract and ownership.
Use mechanism and reports pages to map symptoms to root causes.
Use debug and worked-example pages for war-room practice.
Close with checklist and PPA pages before signing any change.

Late macro move violated quiet-zone assumptions and caused intermittent converter noise excursions.
Review macro adjacency
Re-check guard assumptions
Re-run PV with correct deck variant
