Summary

In this interview, Andy Nightingale from Arteris discusses the challenges of data movement in modern chips, particularly in multi-die assemblies. He explains that with the rise of AI and sensors, the network-on-chip (NoC) has become the critical path for data movement. The conversation covers the need for quality of service (QoS) to manage bandwidth and latency for various IP blocks, the trade-offs between coherent and non-coherent designs, and the benefits of scaling out with chiplets. Nightingale highlights that non-coherent multi-die configurations are already in use, while cache coherency across dies is more complex. He discusses the advantages of disaggregating dies, such as using different process nodes for different functions, and the ability to upgrade individual dies without changing the rest of the system. The interview also touches on the evolving standards for chiplet interconnects, emphasizing a pragmatic approach. Finally, Nightingale describes how the design and verification flow must adapt, with a shift-left strategy using digital twins to de-risk the process.
