Embracing the Chiplet Journey: The Shift to Chiplet-Based Architectures

The semiconductor industry is facing a paradigm shift. Traditional scaling, once driven by Moore’s Law, is slowing down. For years, moving to smaller process nodes led to lower transistor costs and better performance. However, scaling from node to node now offers fewer benefits as wafer costs rise much more than the historical 10% with each new node. This, combined with the physical limits of silicon, makes traditional scaling increasingly unviable. This reality is driving the need for new approaches, with chiplet-based architectures emerging as a solution.

The chiplet-based approach offers significant advantages, including modularity for faster and cost-effective design, customization for meeting specific performance and power needs, improved yield by reducing complexity, optimized power and performance through tailored IP integration, and scalability that allows for seamless upgrades without full-chip redesigns.

Boyd Phelps, Senior VP and GM, Silicon Solutions Group, Cadence, gave a keynote presentation at the Chiplet Summit 2025 conference. His talk addressed how the industry is embracing the chiplet journey, the driving factors for rapid adoption, and how Cadence is bringing value to its customer base.
