As 3DIC adoption ramps up, it’s becoming clear: microarchitecture needs a rethink. So how do you design hardware that can survive and thrive in the new era of stacked silicon?

In this episode of the Siemens 3D IC Podcast, host John McMillan speaks with Pratyush Kamal, Director of R&D for 3D IC Solutions Engineering at Siemens Digital Industries. With decades of experience spanning Qualcomm and Google, Pratyush brings deep insight into the evolution of IC design—and how 3D integration is transforming every layer of the design stack.

From redefining how and when microarchitecture decisions are made to overcoming the thermal, testing, and failure analysis challenges that come with 3D stacking, this episode dives into the critical topics design teams need to understand today.

You’ll also hear how AI, automation, and cross-disciplinary expertise are reshaping team roles—and why software-defined silicon is redefining the design process itself.

This episode is essential listening for IC architects, system designers, and packaging engineers navigating the transition to advanced 3D IC platforms.
