SUMMARY:Staged Snapshots for Firmware-Hardware Collaborative Debug
DESCRIPTION:Pretty Jacob, Carsten Otte, Joachim Paret, Arun Joseph, and Ma
 ya Safieddine (IBM Research)\n\nStaged snapshot-based collaborative debug 
 across firmware and hardware environments bridges the gap between fast mic
 rocode simulators and slow, but fully observable, system simulations. Our 
 approach captures a minimal architected state—registers and selected memor
 y—from a firmware simulator at post‑IML and replays it into RTL system sim
 ulation, emulation, and back, using profile‑driven, protobuf‑encoded snaps
 hots and testbench drivers to reconstruct non‑architected state. This deco
 upled, bidirectional flow enables HW and FW teams to debug the same failur
 e in their native environments, without weeks of manual state reconstructi
 on, reducing debug turn around time from weeks to hours, while shrinking s
 napshot size and cutting engineer effort by over an order of magnitude. De
 ployed on IBM Z17 for HW–FW interaction bugs, the framework offers better 
 debug state quality, and the schema‑based design is generalizable to other
  firmware simulators and architectures, making it a practical for next‑gen
 eration systems.\n\nTopics: AI, Chiplet, Design, EDA, Quantum, Security, S
