  • Why create a MyCST Account ?

    A MyCST account may facilitate your access to many of the offerings on the CST website, for example the registration for eSeminars and the watching of eSeminars recordings, setting email preferences, and there is more functionality to come. It is required to participate in workshops and trainings.

  • Personal PreferencesAllows you to update your email preferences and areas of interest. It helps us to personalize your experience.

  • EventsSearch for events by location, industry and application. Once you are registered, you will be able to manage your registrations and check important details about your events. This section also provides you with a repository for Workshop & Training material.

  • LibraryYou can collect articles you find on the CST website to reference or read later by clicking on the “Add this article” button at the bottom of the article page.

  • Create Your Own Account
  • Need technical Support ?

    Customers can customize their accounts once they have completed the account creation process. This platform acts as vivid interface between CST and our customers.

    We therefore offer access to the latest Service Packs (including an automatic notification that a new Service Pack is available), a steadily growing database of Frequently Asked Questions (FAQs), Application Notes and Training Videos, as well as an individual FTP section for easy exchange of large files with our support team.

  • Do I need an Account?To access the Support Site a valid maintenance contract and a one-time registration is required.

    Please note that your Support login does not work for the MyCST account.

CST – Computer Simulation Technology

Idem

Idem is a user friendly tool for the generation of macromodels of linear lumped multi-port structures (e.g., via fields, connectors, packages, discontinuities, etc.), known from their input-output port responses. The raw characterization of the structure can come from measurement or simulation, either in frequency domain or in time domain. A suite of advanced and well conditioned rational fitting modules grants applicability to virtually any kind of characterization. The resulting models are cast in common SPICE formats for the system-level simulations required in your design flow. Thus, Idem enables SPICE 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.

Several competitors claim that their models are accurate, fast, stable, passive, causal, robust, and more... We claim our models are better. Idem uses best-in-class algorithms to build macromodels, including a proprietary data causality certification module based on Hilbert transform, highly scalable rational fitting modules enabling unlimited port counts, and top-class passivity enforcement schemes for safe and stable transient simulations. Thanks to the multiprocessing module, Idem guarantees an efficient macromodeling of ever-larger structures

If you have not tried Idem, you cannot understand its power.

  • Fully-developed GUI: all algorithms of Idem are linked to an intuitive Graphical User Interface
  • Multiplatform: Idem is available for Windows and Linux platforms
  • Easy to use: little expert knowledge is needed for using most algorithms with standard settings
  • Flexible and powerful: a rich set of control parameters is available for advanced users
  • Accurate and efficient: Idem uses state-of-the-art fitting algorithms for rational approximations with guaranteed passivity
  • Unlimited ports: splitting strategies are adopted for handling large port counts without excessive memory requirements
  • Data import: import filters are available for Touchstone and other common data formats
  • Model export: models can be synthesized as equivalent circuits into common SPICE formats
  • Causality: A proprietary causality check module allows detecting possible measurement/simulation errors that compromise the physical consistency of the raw data.
  • Passivity: Top-class algorithms are available for model passivity enforcement, ensuring safe use of models in system-level EMC/SI/PI simulations.
  • Multiprocessing: An advanced module enables multi-thread capabilities, with an extraordinary speed-up in simulation time and guaranteeing an efficient macromodeling of ever-larger structures.
