Overview
Via discontinuities in signal paths have significant impact on signal integrity for high speed designs. A quick way to build via models and then simulate them is essential for SI engineers. ViaExpert is made specially for this purpose. To quickly build via models, it provides multiple ways including built-in templates, direct layout file import, and a combined flow which takes advantage of both the layout trace breakout and built-in templates. To quickly simulate models, it deploys two solver technologies, one is a Finite Element Method (FEM) solver, and the other is a hybrid solver with an order of magnitude speedup compared to the FEM solver. Both adopt distributed processing and multi-core parallelization, which adds another level of acceleration. Auto port generation simplifies EM analysis setup. Parametric sweep and optimization help to achieve design convergence. It provides export to HFSS for quick benchmarking purpose.
