Marvell: Accelerating Interposer Design with Early Signal Integrity Analysis

Date: Apr 28, 2026 | 9:00 AM PST

In this webinar, Marvell will present how its team accelerates passive interposer routing for advanced 2.5D/3.5D multi die designs by bringing early, physics based signal integrity feedback into each routing iteration. Rather than relying on repeated, compute intensive 3D FEM cycles during development, Marvell uses a Method of Moments (MoM) early SI check available within Synopsys 3DIC Compiler to evaluate routing with real parasitics and simulation data, fast enough to support rapid iteration and safer exploration of auto routing strategies.  Marvell will also share practical correlation takeaways, where MoM tracks FEM strongly and where additional margin and correlation work may be needed ahead of final signoff.

What you’ll learn

  • Why traditional interposer SI signoff can become a major schedule bottleneck
  • How early SI analysis with MoM differs from FEM and where it fits best
  • How to use physics-based SI feedback during interposer routing iterations
  • When and how to correlate early SI results with FEM for confidence and margin
  • How early SI enables faster convergence and broader design space exploration
