ANSYS offers signal integrity, power integrity and EMI/EMC solutions through a combination of electromagnetic and circuit simulation tools. ANSYS HFSS software is a full-wave 3-D electromagnetic field solver, and ANSYS SIwave technology is the 2.5-D hybrid electromagnetic field solver designed for package and board design. These two high-fidelity electromagnetic field simulation products are tightly integrated with ANSYS DesignerSI, our high-speed circuit and system simulation tool.

ANSYS SIwave calculates resonances between power and ground planes.
