What is IdEM?

IdEM is a user-friendly tool for the generation of macromodels of linear lumped multi-port structures (via fields, connectors, packages, discontinuities,…), known from their input-output port responses. The raw characterization of the structure can come from measurement or simulation. A suite of advanced and well-conditioned rational fitting modules grants applicability to virtually any kind of characterization. IdEM casts the resulting models in standard SPICE formats for system-level simulations in your design flow. Thus, IdEM enables SPICE model extraction and processing for any kind of linear structure, component, interconnect, package, whatever your native characterization and application area.

IdEM is an optional part of CST Studio Suite® and is also available as a stand-alone offering.

Why IdEM?

IdEM uses best-in-class algorithms to build macromodels, including:

  • Proprietary data causality certification module based on the Hilbert transform
  • Highly scalable rational fitting modules enabling unlimited port counts
  • Top-class passivity enforcement schemes for safe and stable transient simulations.

Thanks to the multiprocessing module, IdEM enables efficient macromodeling of ever-larger structures.
