HERMES SI – Package and Board level signal integrity analysis

Background

Impedance discontinuity in the signal path has a significant impact on signal integrity for high speed channel design. Among the many discontinuities, via discontinuity plays an important role in the high speed channel design. Three-dimensional full-wave EM simulation is constantly used to analyze via discontinuity, but there are many defects in the traditional 3D full-wave simulation, for example, the model creation is complex and time-consuming.

Product Introduction

HERMES SI is an application which use three-dimensional full-wave EM simulation to deal with high-speed serial circuit. It provides a fast and accurate import brd models, check the signal integrity metrics such as insertion loss, return loss, and crosstalk; it also allows designer to perform simulation and track processing for the post-layout model.
