Product Overview

HFSS™ utilizes a 3D full-wave Finite Element Method (FEM) to compute the electrical behavior of high-frequency and high-speed components. With HFSS, engineers can extract parasitic parameters (S, Y, Z), visualize 3D electromagnetic fields (near- and far-field), and generate Full-Wave SPICE™ models to effectively evaluate signal quality, including transmission path losses, reflection loss due to impedance mismatches, parasitic coupling, and radiation.

HFSS v11 features new higher-order, hierarchical basis functions combined with an iterative solver that provides accurate fields, smaller meshes, and more efficient solutions for large, multi-wavelength structures. A new fault tolerant, high-quality finite element meshing algorithm further enhances HFSS's ability to simulate very complex geometric models, including models imported from 3D CAD environments. HFSS is dynamically linked with Nexxim® and Ansoft Designer® to create a powerful electromagnetic-based design flow. This design flow enables users to combine complex, highly nonlinear circuits with transistor-level detail and 3D full-wave accurate component models to solve challenging high-performance electronic designs.
