Google: Scaling HBM Signal Integrity Signoff for Large‑Scale 2.5D Packages with Parallel Analysis

Featured Speakers:

• Anna Gao, Hardware Engineer, Google

In this Synopsys Webinar, Google will present how its team addresses large‑scale HBM signal integrity challenges using a scalable signoff methodology, originally presented at Synopsys Converge. The session introduces a hybrid workflow built on Synopsys 3DIC Compiler that combines high‑accuracy FEM analysis for a representative Golden DWORD with fast, parallel Method‑of‑Moments (MoM) analysis across the full design. This approach enables efficient validation of thousands of high‑speed channels, allowing teams to identify routing issues, missing ground structures, and SI risks earlier, without the runtime constraints of full‑chip FEM extraction. By shifting SI confidence earlier and enabling parallel analysis, designers can reduce turnaround time, improve coverage, and converge faster on signoff‑quality HBM implementations.

Why You Should Attend:

• How Google scales HBM signal integrity validation across large multi‑die designs 
• Why traditional full‑chip FEM flows do not scale for modern HBM systems 
• How the Golden DWORD methodology enables accurate, reference‑based SI validation 
• How parallel MoM‑based analysis accelerates full‑chip SI coverage 
• How early SI insight improves design convergence and reduces signoff risk
