The simultaneous maturation of CFET and buried power rails signals a paradigm fracture, not a generational step. Once sub-2nm nodes lock in vertical compute-power coupling, the 2D parasitic-extraction model that has underpinned EDA for three decades becomes structurally obsolete. This is why agentic AI in EDA is not a feature upgrade—it is a survival mechanism for Synopsys, Cadence, and Siemens EDA against a fundamentally different simulation topology. The real strategic battleground sits at the packaging layer. Chiplet interconnect standardization (UCIe) will determine whether advanced packaging remains TSMC's moat or becomes shared industry infrastructure. If interconnect bandwidth lags CFET's compute density, the most advanced transistors become isolated islands—expensive, but architecturally irrelevant. On the compliance front, High-NA EUV geographic concentration means CFET mass production is inherently tethered to specific supply-chain nodes. Any escalation in export controls converts a technology race into a capacity standoff. Within 12–24 months, 6G architecture decisions will retroactively lock RF front-end process choices, creating an application-defines-process feedback loop. The scarce resource will no longer be the transistor itself, but cross-domain engineering capability spanning 3D power delivery, interconnect protocols, and AI-assisted verification.
