In close cooperation with Ansoft Corp., the company is offering customized simulation models for the Ansoft designer and Nexxim circuit simulation programs. The models can be integrated directly into the commercial and student versions of the respective simulation environment, with advanced inductive components already contained in the development process. Existing libraries for 12 single and double chokes have been updated and extended. In addition, new libraries have been created for four power inductors and one leaded RF choke. All libraries are available in versions for PSPICE, HSPICE, and Ansoft Designer/Nexxim.
