A Path for Continued Semiconductor Innovation

There are a couple of popular ways to approach a multi-die system architecture. One is disaggregation, where a large die is partitioned into smaller dies to improve system yield and cost compared to monolithic dies. This approach can be applied to heterogenous and homogenous designs. Another common approach is to assemble dies from different process technologies to optimize system functionality and performance. Such a system may contain dies designated for digital compute, analog, memory, and optical compute, each at a process node ideal for its target functionality. In the long run, fabricating a design consisting of multiple, smaller dies versus a large, monolithic SoC will produce better results in terms of yield.

The emergence of advanced packaging technologies, such as silicon interposers, redistribution layer (RDL) interposers, and hybrid bonding—has paved the way for multi-die systems. Industry standards like HBM3 for high-density memory and UCIe for secure die-to-die connectivity are also key enablers, ensuring quality, consistency, and interoperability.

Another piece of the puzzle lies in the design and verification flow. In the 2D design world, teams commonly work on their portion of the design and then turn their results over to the next team in line. For multi-die systems, teams should address the challenges together, analyzing parameters such as power consumption, signal integrity, proximity effects, and heat dissipation with respect to each other.

EDA companies need to think broadly as well when developing their tool flows. A scalable, cohesive, reliable, and comprehensive multi-die system solution can enhance productivity while enabling teams to meet their time-to-market and PPA targets. To learn more about how steps including architecture exploration, system implementation, die-to-die connectivity, software development and software/hardware validation, verification, signoff, silicon lifecycle management, and testing can be addressed from a multi-die system perspective, read my new paper, “How Multi-Die Systems Are Transforming Electronic Design: A Comprehensive Approach for Integrating Heterogeneous Dies.”
