  • Parametric Simulation with SIwave in the Ansys Electronics Desktop

As a result of progressive miniaturization, greater integration density and higher switching speeds, the printed circuit board itself has become a complex component as a carrier for circuit components. In order to achieve a ‘First Time Right’ development process, the use of simulation is essential for designers and layout engineers. Only with simulation can electromagnetic field effects be considered for all aspects of signal transmission.

This training course provides technical know-how on signal and power supply integrity simulation in Ansys SIwave. You will deepen your acquired knowledge via numerous practical examples (e.g. Computer on Module - COM), which you can use in your future daily work.

The training is aimed at hardware developers and PCB designers for all types of electronics who want to identify optimized design variants in the early design phase or need to provide well-founded predictions on the behavior of their layouts.

In the course you will be taught to identify, analyze and optimize critical points in PCB designs. To meet design requirements (e.g. EMC requirements and industry standards), you will check the virtual prototype of the PCB by simulations and evaluate different variants in all phases of the design process. This procedure allows you to significantly reduce development times.

Do you have questions on the training?

When will I receive the final confirmation for my training booking?

Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.  

As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information on how to get to the venue. We recommend that you wait until you have received this final confirmation before booking your travel and accommodation.

If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to help you change your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.

When is the sign-up deadline for a training?

Training places will generally be allocated based on the order in which attendees sign up. For this reason, we always recommend booking for your desired date as early as possible.

As long as a coures still has free places, it can be booked.

At what time do the training courses begin and end?

Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT).
