In this workshop, Coilsys is introduced for inductor design and synthesis. Coilsys is a new tool in ADS2017 for P-cell creation, model synthesis and inductor finding. It provides a turn-key solution for user to design and optimize inductors and transformers quickly. To obtain more flexibility, users can use AEL macro for customized layout. AMC can create EM based model for parameterized layout. The parameterized layout is not only useful in inductor design but also in antenna, package and other passive components. Momentum provides a fast and accurate EM solver for inductor simulation. FEM can be an alternative in ADS environment.
