Title: Governing the 1.8 Tb/s Reality Gap: EM Corridors, Power Architectures, and Agentic AI
The 2027 Challenge: As we push AI chiplet platforms toward 1.2 to 1.8 Tb/s interconnect speeds, we are hitting a physical wall. At these frequencies, the design is no longer a collection of blocks; it is a single, volatile EM Corridor where signal integrity and power delivery are inextricably linked .
The Failure Chain: Current siloes (SI vs. PI) are creating a massive Reality Gap. A transient in the Chiplet Power Architecture (CPA) creates a thermal shift, which alters the dielectric properties of the substrate, causing an EM failure in the 1.8 Tb/s link. Traditional tools see the "effect" (Eye-closure), but they miss the "cause" (The Power Transient) .
The Solution: SEGA-AI™ Governance To master this, we are deploying the SEGA-AI Intelligence Layer on top of our deterministic backbone :
EM Corridor Control: Enforcing a XX% Correlation Rule between simulation and lab for all high-speed paths.
CPA (Chiplet Power Architecture) Integrity: Using Authorized Evidence to bound power mesh transients before they destabilize the EM environment.
Causality Intelligence: An Agentic AI engine that traces these cross-domain failure chains in real-time, providing Prescriptive Recommendations for closure .
I will be detailing this "Deterministic Sovereignty" model during my Keynote at DesignCon 2027.
It demonstrates Prescriptive Analytics. Instead of telling the engineer to "fix the signal," the AI recommends the Next Best Bounded Action: "Recalibrate PDN Decoupling at Location X".
