LEGOSim: A Unified Parallel Simulation Framework for Multi-chiplet Heterogeneous Integration

Year: 2025

Type: conference-paper

Abstract: The rise of multi-chiplet integration challenges existing simulators like gem5 for efficiently simulating heterogeneous multiple-chiplet systems due to incapability to modularly integrate heterogeneous chiplets and high synchronization overheads in parallel simulation.To address these limitations, this paper introduces LEGOSim, a unified parallel simulation framework capable of flexibly integrating various open-source and in-house designed chiplet simulators as processes in parallel simulation, referred to as "simlets" with minimal modifications needed.It introduces an on-demand synchronization protocol with adaptive MICRO '25,
