A new technical paper titled “System-Level Validation Across Multiple Platforms to build a Robust 2.5D Multi Foundry Chiplet Solution” was published by researchers at Intel Corporation.
Abstract
“The proliferation of chiplet-based designs, driven by the escalating computational demands of AI, presents unique validation challenges when integrating heterogenous chiplets. This paper investigates the complexities of realizing large-scale chiplet systems with passive silicon base scaling beyond multi-reticle approaches, particularly addressing the heterogeneity introduced by varying functionalities with diverse manufacturing origins (multiple foundries). We propose three distinct validation platforms: hardware-aware software enablement, FPGA-based prototyping for seamless hardware porting, and specialized infrastructure for silicon system measurement, to optimize system efficiency. These platforms provide a structured framework for validating and deploying complex chiplet heterogenous architectures, exemplified by our target 20-chiplet System-In-Package (SIP). We demonstrate mapping workloads onto the hashing accelerator following the proposed approach to obtain speed up between 4x – 5x compared against CPU.”
