The semiconductor industry is facing rising complexity driven by expanding AI workloads and advanced computing requirements. Designers are increasingly adopting heterogeneous multi-die integration, combining dies built on different process technologies within a single package to support diverse functional requirements. As highlighted by Jayraj Nair, multiphysics simulation is evolving from a verification activity to a core part of the design process.
Key challenges include:
- Power-thermal interactions, where electrical behavior and thermal conditions influence one another
- Signal integrity across high-bandwidth die-to-die connections
- Mechanical stresses associated with thermal expansion in advanced packaging
The blog also discusses digital engineering and model-based systems approaches that aim to connect traditionally separate engineering domains and support collaboration across increasingly complex chip development workflows.
