Ansoft [1] tools integrate electromagnetic, circuit, and system engineering in a complete design environment. Some of the most interesting applications are the following:
HFSS is a three-dimensional full-wave electromagnetic simulation tool for S-parameter, SPICE extraction, and field computation of high-frequency and high-speed components. It models on-chip embedded passive components, integrated circuit packages, printed circuit board interconnects, antennas, radio frequency and microwave components, and biomedical devices. It uses higher-order hierarchical shape functions and an iterative solver, which provides efficient and accurate field solutions at coarser meshes. A high-quality finite element mesher supports discretization of complex geometries.
Q3D Extractor provides high-performance three-dimensional and two-dimensional parasitic extraction of electronic components based on quasi-static electromagnetic-field simulation. The method of moments and the finite element method are used to obtain three-dimensional RLC and two-dimensional RLCG values. An equivalent SPICE circuit model can be automatically generated. TPA (Turbo Package Analyzer) provides automated parasitic extraction for integrated circuit packages. Lumped or distributed RLC parameters in integrated circuit packages for analog radio frequency and high-speed digital applications are obtained automatically.
