EMI Simulation for Electronic Applications

4 Apr 2022

We are increasingly unable to operate without communication equipment, sensors in vehicles, antennas in our facilities, and other electronic equipment.  A challenge that is associated with this dependence is a phenomenon called electromagnetic interference (EMI). 

The plane crew asks everyone to switch off their electronic devices whenever they board. When you switch on the television and radio simultaneously, you note a noisy disturbance. These are just examples of the numerous instances of EMI. 

Owing to the increasing demand for electronic applications, designers must take into account the effects of EMI. It would be extremely annoying if someone talking on their phone next to you causes interference to your audio gadget. 

It may be impossible to eliminate all EMI issues from electronic equipment, but designers can surely improve their services to reduce the effects to a minimum. EMI simulation is a worthy instrument for reducing EMI problems.

But what makes this simulation effective? 


The Relevance of EMI Simulation 

Electronic equipment designers have increasingly worried about EM compatibility (EMC) and electromagnetic interference (EMI). Initially, EMI wasn’t a consideration until the finished product reached the compliance testing stage. 

Now that electronic components are growing smaller and the IoT exists, instances of EMI problems are prevalent. One of the biggest concerns is the high cost of countering these issues in lower-cost devices and assemblies. 

IoT gadgets are inexpensive and tiny, so designers and manufacturers want to avoid the costs that come with shielding and making enclosures. 

With evolving challenges, electronic designers have their work cut out. They must have the right set of knowledge and tools to comply and succeed in this competitive industry. 


EMI Simulation Early in the Design

No element of today’s electronics design offers a bigger challenge than guaranteeing the healthy coexistence of various digital interfaces found in the devices. The goal of every engineer is to ensure that every interface can perform as excellently as it would in isolation. 

That modern electronics come with numerous features means that it can be difficult to predict the potential of a harmful interaction. Usually, problems are discovered during product testing. Since this calls for redesign, it delays product release as the trial-and-error solutions are administered. 


As digital technologies become more integrated, it is becoming difficult to achieve EMI/EMC compliance standards. Adherence to these standards would mean prototype redesign, a method that not only increases prototyping expenses but also delays product introduction. 

EMI simulation for electronic applications is applicable in both the troubleshooting and design stages. Using the method earlier during the design is recommendable because it can render troubleshooting in the latter stages unnecessary. 

The simulation doesn’t require a tangible prototype, yet it can give valuable insight into fundamental issues. Apart from that, EMI simulation provides data that is incomparable to what you could get from physical measurements in terms of details. 


The Right Provider for EMI Simulation 

Do you want your next electronic project to progress with speed and still adhere to EMI standards? The answer is in turning to a reputable company with robust simulation platforms. 

You want to get it “right the first time” so that you can meet your deadline. This would mean optimization of the design process and reduction of the analysis timespan.
