      This video shows how easy it is to define HFSS Regions in ANSYS SIwave. This hybrid solution technique enables you to obtain 3D full-wave accuracy for the S-parameters of critical nets on a printed circuit board. To demonstrate this feature, a very large PCB, 60 cm long and 42 cm wide, with 20 metal layers is used in ANSYS SIwave. High-speed differential pairs are identified on the PCB and region extents are drawn. Everything else is executed in an automated fashion in SIwave and the board is simulated with and without HFSS Regions. The video also discusses the typical 3D region structures in an electrical CAD (ECAD) design where you can best employ this hybrid solver technique.
