The race to build larger, more capable AI systems has fundamentally changed semiconductor design. As the industry embraces heterogeneous integration and chiplet-based architecture, performance is no longer the only measure of success. Increasingly, the ability to prove that every component can be trusted throughout its lifecycle is becoming just as critical.
The semiconductor industry has largely solved the engineering challenges of building chiplet-based systems. Now it faces a far more difficult question:
Can every chiplet in that package be trusted—not just at deployment, but throughout its entire journey from design to system assembly?
As AI systems become larger, more modular, and increasingly assembled from chiplets sourced across multiple organizations, security is no longer limited to protecting the finished device. It must extend across every stage of the lifecycle—from RTL design and manufacturing to provisioning, packaging, and final system integration.
Every chiplet moves through multiple organizations before becoming part of a finished system. Every handoff, from design and manufacturing to provisioning, packaging, assembly, and deployment creates another point where system integrity must be preserved. Every one of those transitions is also a potential attack surface.
This is why security can no longer be confined to the chip itself. It must establish an unbroken chain of custody across the entire silicon supply chain, ensuring that every participant can verify the integrity, ownership, and authenticity of the components they receive.
