About this Webinar

Silicon integration technology and associated devices have undergone an impressive evolution over the last decades. Device and circuit density increase due to CMOS devices' physical scaling and expansion in the Front-End-of-Line (FEOL) and passive devices in the Back-End-of-Line (BEOL).

Silicon integrated devices are ruled by complex electromagnetic (EM) effects, including electric and magnetic field coupling and interaction with the semiconductor bulk substrate. As chips grow, complexity, operating frequency, and integration techniques push integration boundaries from 2D SoCs to 3D stacked ICs. Consequently, it becomes critical to analyze electromagnetic coupling to ensure working silicon accurately.

This webinar focuses on Ansys RaptorX, the hybrid solver that powers the Ansys silicon-optimized electromagnetic simulation portfolio. Starting from Maxwell's equations, we'll present the fundamentals of the modeling methodology. Attendees will have a chance to understand how and why the combination of Partial Element Equivalent Circuit and Random Walk solvers into a single hybrid method (PEEC-RW) can provide accurate and efficient models for modern SoC and 3DIC designs.
