  • 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

EMC Simulation of Automotive Ethernet

Rapidly escalating levels of data rates are projected to grow even further in the future, fueled by trends like the upcoming introduction of connected and autonomous vehicles. This eSeminar will present simulations of EMC related aspects of the automotive Ethernet: the effect of the PCB layout on the emission from an automotive Ethernet channel, crosstalk from the automotive Ethernet channel to other cables inside one harness, and susceptibility of the channel based on the BCI testing method. BroadR-Reach® is a point-to-point Ethernet Physical Layer standard for automotive applications, allowing full-duplex communication between two devices over an unshielded twisted-wire pair (UTP) at 100 Mb/s, with plans to further increase it to 1000 Mb/s. Unshielded twisted cables are lightweight and cost effective, but they make compliance of the BroadR-Reach® Ethernet with automotive EMC requirements a challenging task.
