RTL owner: fundamentals -> AMBA -> memory interfaces -> debug playbooks -> PPA impact.
Verification owner: fundamentals -> protocol verification -> AMBA/coherence -> interview drills.
SoC architect: fundamentals -> bandwidth budgeting -> coherence -> PCIe/CXL -> comparison matrices.
Bring-up engineer: memory interfaces -> PCIe/CXL -> high-speed I/O -> waveform debug.
