Driving innovation in 3D IC systems

As AI compute demand accelerates and traditional 2D scaling approaches economic and physical limits, engineering teams are increasingly turning to 3D IC technology and heterogeneous integration to sustain performance scaling. However, the shift from monolithic SoC architectures to advanced multi-die and chiplet-based systems introduces unprecedented system complexity. Success in this new paradigm requires not only new packaging approaches, but also new design methodologies, verification flows, and sign-off strategies. While the 3D IC manufacturing technology may have become mainstream, there are some foundational enablers for a successful heterogeneous 3D IC implementation.

This video explores the foundational enablers required for successful 3D IC implementation and outlines the latest technology and methodology trends shaping current design starts.

3D IC Design Trends

Modern 3D IC packages integrate logic dies, high-bandwidth memory (HBM) stacks, interposers, and advanced substrates in tightly coupled configurations. These systems push the boundaries of power density, interconnect scale, and thermal behavior.

Key trends highlighted in the video include:

• Chiplet-based architectures enabling modular scalability and faster time to market
• System-technology co-optimization (STCO) balancing performance, power, cost, and yield
• Increasing emphasis on cross-domain optimization across electrical, thermal, and mechanical constraints

Methodology and Tool Challenges

While 3D IC architectures unlock new performance opportunities, they also expose gaps in traditional workflows. Engineering teams must now address:

• System-level architectural complexity
• Non-linear multiphysics interactions across stacked dies
• Expanded 3D IC verification and reliability sign-off requirements
• Massive data scale and runtime demand

Traditional siloed flows are no longer sufficient. True STCO is now a design requirement.

New Design Imperatives

One of the most important emerging concepts in advanced packaging is multiphysics-driven floorplanning. By embedding thermal, mechanical, and electrical awareness at the earliest stages of architecture definition, teams can reduce late-stage redesign risk and improve performance predictability.

As system integration becomes the primary innovation lever, Siemens uniquely enables multiphysics-driven exploration, 3D implementation, verification, and full-system sign-off within a unified workflow. By addressing thermal, mechanical, electrical, and reliability challenges early in the design cycle, Siemens solutions help engineering teams reduce risk, accelerate time-to-market, and confidently scale next-generation AI and heterogeneous integration designs.
