Replay‑based Validation as a Scalable Methodology for Chiplet‑based Systems (Intel, Synopsys)

Researchers from Intel, Nvidia, and Synopsys published a technical paper on an ODIN-based CPU-GPU architecture with replay-driven simulation and emulation. The paper focuses on the integration of CPU and GPU technologies in chiplet-based architectures, highlighting the challenges of pre-silicon validation for CPU-GPU subsystems. The methodology presented leverages deterministic waveform capture and replay to accelerate debug, improve integration confidence, and enable end-to-end system boot and workload execution within a single quarter. This approach demonstrates the effectiveness of replay-based validation as a scalable methodology for chiplet-based systems.
