Paper Title: Model-Based System Design for Chiplet-Based Architectures

Paper Abstract: Chiplets and heterogeneous integration are changing the entire process of creating electronic systems. As hardware moves from monolithic devices to multi-chiplet architectures and software from standalone applications to coordinated and distributed services, designers must rethink workflows from the ground up to optimize performance, flexibility, and scalability. They must also include ways to make systems more sustainable during their entire lifetimes. Optimizing system development flow is essential to maximize global efficiency for algorithms, software stack, data coding, chiplet architecture, and advanced 3D integration. To manage a highly complex development flow requires the creation of models at various levels of abstraction, including models of computation and communications, digital twins, design platforms, and environmental impact models. Model-based system designs developed at CEA, together with several chiplet-enabling technology bricks, help with flows covering applications software, automotive electronics architectures, and integration technologies.

Author Bio: Denis Dutoit is senior program manager for advanced computing and digital architectures at CEA-List, one of the world’s largest organizations for research in microelectronics, architecture, and system integration. He coordinated the European ExaNoDe project that developed a computer node demonstrator combining chiplets, an active interposer, and bare dies in a System-in-Package (SiP). He has also contributed to the architecture of the European Processor Initiative (EPI). His current focus is on architecture pathfinding into chiplet-based designs for automotive electronics. Before joining CEA, he was a system-on-chip architect at ST Microelectronics and ST Ericsson. He has authored or coauthored more than 20 articles, including invited talks and tutorials at IEEE conferences. He earned a PhD in signal processing from Telecom Paris (ENST).
