Memory wall first
The memory wall, CPU-centric computing limits, accelerator explosion, data-movement costs — the engineering forces that produced CXL before a single protocol layer is named.
Interview-ready depth
A dedicated interview module plus per-chapter interview weighting — CXL.io vs .cache vs .mem, device-type selection, memory pooling, fabric architecture, coherency flows, silicon-bring-up debug.
Design → verify → debug
Protocol-engine / transaction / memory-controller / device RTL pipelines, SVA / UVM coherency verification, and trace-driven silicon debugging — the full engineering loop for a CXL link.
