SerDes lane architecture, equalization behavior, link training, and SI-aware debug from digital integration perspective.
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.
