EMC simulations uncover the underlying physics.

Electromagnetic Compatibility (EMC) Simulations

We use Dassualt Systemes’ CST Studio to perform EMC simulations at E3.  EMC simulations show us where the risk areas are on new designs and allow us to optimize the design virtually. We also use simulation tools to help us understand and solve failures found in testing.  We perform a wide variety of EMC simulations:

•Shielding effectiveness (PCB, enclosure, vehicular)

•Coupling & crosstalk (PCB, cables, magnetics, vehicular)

•PCB trace routing and planes design

•Cable and connector design optimizations

•RF Radiated & conducted emissions

•RF Radiated & conducted immunity

•Electrostatic discharge (ESD)

•Filter design

•Power integrity

•Signal integrity

Simulation tools have advanced over the years allowing us to import your ECAD and MCAD files, assign EM properties and perform the analysis efficiently.

All modeling is a compromise between run time, model fidelity and accuracy of results. We use a trend modeling approach that is both time efficient and accurate enough to support good design practices. Having spent over two decades modeling and correlating EMC problems with different solvers and tools, we have established a proven process and correlations to bring confidence to every job and meet our customer’s needs.

Capabilities

We utilize in-house and US-based cloud computing to accelerate our EMC simulations so they can make an impact within your design cycle.  Beyond our computing power, we have experience modeling and simulating integrated circuits, packages, printed circuit boards (PCBs), cables, connectors, enclosures, systems, vehicles and whole environments. Here are a few examples of simulations performed:

The CST Studio tool set from Dassault Systemes offers a wide variety of modeling opportunities. The following illustrates different tools with examples of the types of simulations that can be performed. The Hybrid System Assembly Modeling (SAM) approach is of keen interest when modeling challenging problems:

EMC Simulation Success Stories

We recently used CST Studio to perform a virtual Radiated Immunity test according to ISO11452. Our customer required both a near-field antenna and Absorber Lined Shielded Enclosure (ALSE) simulations in advance of testing in our lab. We imported their PCB design from Altium and their mechanical enclosure design from CATIA. The simulation allowed us to identify strong interference coupling from the EMI fields exposure and optimize the design virtually. After finalizing the design, they released it for prototyping, built assemblies and tested the devices.

The effort put into simulation resulted in a FULL PASS during over-testing to their immunity requirements. They were amazed at the value of simulation. Prior to using simulation in their development process, failures were common and they had spent significant time debugging the problem in the lab which caused delays and was an unplanned cost in the program budget.

Going forward, the customer now builds EMC Simulations into their development process and has already had several successful program launches because of it.
