Simulation Tools for Electromagnetic Interference

This post originally appeared on the Dassault Systèmes blog.

The world of electromagnetic devices is rapidly expanding, to include everything from smart devices in our homes to medical devices in and around our bodies. This technology is opening up many doors, allowing us to live more enriching and even healthier lives, but, like all good things, the technology comes with potential complications. When discussing electromagnetics, the term EMC/EMI often comes up. EMC stands for electromagnetic compatibility, which involves the unintentional generation and reception of electromagnetic energy. This energy can cause electromagnetic interference (EMI) and even damage in devices that unwittingly receive it.

EMC is the ability of an electrical system to properly function in its intended environment without influencing other devices, also known as giving off emissions, or being influenced by surrounding devices (known as immunity or susceptibility.) Emissions and Immunity is a well-regulated area, and compliance with these regulations is critical for all electromagnetic products.

In the past, EMC engineering was associated primarily with measurements, and could only be applied late in the design stage, as a physical prototype was required. If problems appeared, a great deal of effort was required in troubleshooting and applying countermeasures in order to pass rigorous testing requirements. Frequently, only the symptoms were addressed, with the underlying problem remaining undetected. This approach is cost-intensive and can potentially delay the time to market of the device significantly.

Simulation is a valuable tool in mitigating EMC issues, and can be used both during the design phase and during troubleshooting. Using it as early as possible in the design phase, however, has the potential to mitigate the need for later troubleshooting. Simulation can be used without a physical prototype, and can answer important fundamental questions such as whether to use a shielded or unshielded cable, for example. Beyond that, simulation gives access to information that is far beyond what measurement can offer, peering into the depth of products and evaluating the effects of even the tiniest of details.

CST Studio Suite contains a circuit simulator, which can be coupled with the full wave 3D electromagnetic simulation, offering unique possibilities for the user such as the ability to obtain field results that consider an attached circuit. It also allows the user to calculate field distribution at the speed of a circuit simulation as long as the geometry of the device is not changed, thereby greatly reducing the time and effort needed to evaluate a multitude of different circuit configurations and their effect on the system efficacy.

A tool called BOARDCHECK can be used very early in the design process to visually highlight potential problems and provide a list of all violations on a printed circuit board level. It is fast and easy to use, and is the first step in the process, after which 3D simulation can be run. Overall, CST Studio Suite provides a full spectrum of solutions for EMC/EMI simulation in a single, unified simulation environment. It offers support and openness to third party models and file types, such as CAD, PCB layouts, spice, IBIS, and more. It can be easily integrated into existing toolchains and offers a variety of solvers for different applications and use cases.

eBook: 4 Reasons why ENOVIA is Right for Document Management

Manufacturers have many options for managing documents within their organizations, options that range from the simple to the complex. At the most fundamental level, Microsoft Windows Explorer allows everyone to organize files in a folder structure. But when an organization has more complicated needs – and most do – there are a variety of potential tools to use. Which one you choose will depend on your needs, as well as what enterprise software might already be implemented.

Manufacturers are most likely dealing with not just Microsoft Office documents, but also engineering files. In addition, they typically have complex project management processes and information sharing or collaboration needs. Given those facts, making use of the document/content management capabilities that are integrated with a product lifecycle management (PLM) platform can often be the best option.

This ebook provides an overview of how ENOVIA, part of Dassault Systèmes industry-leading 3DEXPERIENCE PLM platform, provides comprehensive and robust functionality to suit any manufacturer’s content management needs.

Transform Your Organization with Quality 4.0

As more and more industrial and manufacturing organizations digitalize their processes, many are turning their focus to quality initiatives. To evaluate the level of industrial deployment, impact, and effort, LNS Research conducted a global survey in 2019 around a set of quality use cases, asking executives and management in a variety of organizational roles about their readiness for industrial transformation and quality maturity.

Their report, “Quality 4.0: The Quality Innovation Foundry,” categorizes and defines the use cases and examines the state of industrial transformation and quality efforts in the real world.

The Point of IX and Quality 4.0

LNS explains industrial transformation—also IX, Digital Transformation, or smart manufacturing—as “a coordinated approach to leverage digital technologies to create step-change improvement in industrial operations.” The results for those leading companies who have undertaken an IX strategy that includes a Quality 4.0 initiative are impressive:

  • Achieve 90th percentile performance in quality and manufacturing metrics
  • Seven times more likely to have high support for quality from the IT organization
  • Three times more likely to implement any given quality process with technology
  • Have aggressively adopted use cases within quality but also those that extend the quality focus outside the quality function and organization
  • Are significantly more likely to adopt voice of the customer use cases, which represents a monumental change for quality and dramatically impacts their organization
  • Focus on 8 of 33 use cases that deliver the most improvement for the least cost/effort.

Quality 4.0 is all about the digitalization of quality management in order to improve quality monitoring and outcomes, as well as the impact of digitalization on people, processes, and product. LNS further explains:

“At its core, Quality 4.0 is quality data enhanced with other data sources such as manufacturing, machine sensors, supplier management, and product lifecycle data, to derive new analytical insights to be used across the entire enterprise.”

The Challenges

The value of implementing Quality 4.0 initiatives is the ability to realize improved quality, costs, efficiency, market share, and brand recognition. Like any major organizational change, there are challenges associated with accomplishing Quality 4.0 efforts:

  • Poor quality data impeding success
  • A lack of engagement and support by the IT department
  • A lack of an enterprise system that captures not only data but context for that data, such as an enterprise quality management system (EQMS)
  • The old idea that the role of Quality and its expertise is siloed into a single group’s function

This silo concept creates another big organizational issue that was highlighted in the survey: LNS found organizations face hurdles in achieving quality objectives because they view quality as only a department and not a responsibility.

Therefore, it is no surprise that in more than half of the organizations surveyed, quality teams were unaware and not involved in broad, enterprise-wide quality initiatives.

In fact, LNS reports that the most fundamental process change organizations can make is moving quality from a standalone process executed by a low-profile department to a core part of the corporation’s fabric—and to do so by changing the basic role of the quality team to make it core to the organization’s business.

The Quality 4.0 Survey Results

LNS Research tracks (33) Quality 4.0 use cases, divided into six categories. They asked survey respondents not only if they tracked specific manufacturing and quality metrics, but also to rate performance and recent improvements for the measure. The following highlight the 6 categories where progress was being made in Quality 4.0 initiatives:

  • Digital Voice of the Consumer:
    This initiative helps organizations understand customers’ perception of products and quality, and is usually the easiest one to implement and measure. Statistical customer complaint analysis is most commonly deployed from this category, while online benchmarking analysis is identified as the most impactful. The percentage of survey respondents implemented:

    • Online marketplace benchmarking 22%
    • Online marketplace semantic analysis 27%
    • Social media sentiment analysis 23%
    • Statistical warranty analytics 24%
    • Machine learning/AI warranty analytics 22% 
    • Statistical customer complaint analysis 31%
    • Machine learning/AI customer complaint signal detection 22%
  • Connected Supply Chain:
    A category that LNS has found offers the greatest impact on operational metrics.  Many organizations start in this area. The six use cases have already been implemented by 21-34% of companies, and each yielded an average of 31% improvement on the quality and manufacturing metrics. The percentage of survey respondents implemented:

    • Real-time supplier operations visibility 24%
    • Predictive supplied good variance reduction 27%
    • Inspection optimization 34%
    • Multi-tiered supply chain traceability 34%
    • Prescriptive edge analytics 21%
    • Predictive critical parameter optimization 20%
  • Connected Operations:
    Mostly predictive efforts, such as predictive customer experience and predictive end product variance reduction. On average, the six use cases in this category deliver as much value as customer experience use cases, but they are more effort-intensive. The percentage of survey respondents implemented:

    • Predictive Asset maintenance 32%
    • Predictive in-process variance reduction 19%
    • Predictive end-product variance reduction 22%
    • Predictive in-service performance 27%
    • Predictive customer experience 28%
    • Inspection optimization 25%
  • Connected Worker:
    Allows companies to improve worker competency and compliance, while also accelerating the availability, accuracy, and effectiveness of insights received and acted upon. Remote operations centers are the example most actively piloted, though not widely deployed yet, likely due to it representing the biggest effort. The percentage of survey respondents implemented:

    • Mobile/augmented reality customer complaint capture 27%
    • Mobile/augmented reality audits 18%
    • Remote operations centers 15%
    • Engagement and retention apps 22%
    • Connected SOPs 24%
    • Connected training 19%
  • Connected Product:
    Represents the underlying vision of Industry 4.0 and IoT, where manufacturers increasingly connect their products to the internet to provide insight about actual use and performance and enable more proactive service. Performance monitoring is the most widely implemented of all 33 use cases. The percentage of survey respondents implemented:

    • Performance monitoring 30%
    • Predictive maintenance 25%
    • Early Failure detection/recall 20%
    • Remote diagnostics 13%
    • Prescriptive service 11%
  • Robotic Process Automation:
    RPA is a core tool to enable the reengineering of business processes that’s at the heart of IX. Of the three use cases in the category, audit data extraction is the one with the greatest attention—and a low implementation effort however, the impact of the use case is mixed, without significantly higher quality or manufacturing metrics so far. The percentage of survey respondents implemented:

    • Audit data extraction 31%
    • Root cause suggestion 20%
    • Predictive routing 27%

Quality 4.0 Findings

LNS found three major results around Quality 4.0 initiatives:

  1. Positive Impact to the Enterprise. Use case implementations have a positive correlation with more than just quality. Virtually all of the 33 use cases “meaningfully improve both quality and manufacturing performance,” delivering an impact across the enterprise. That validates a core tenant of Quality 4.0, that quality is the responsibility of the whole organization and has an impact enterprise-wide.
  2. Continuous Performance Improvements. The second finding is that the more use cases a company adopts, the better it performs in quality and manufacturing.
  3. A Holistic View of Quality Enterprise-wide. The third finding addresses the effort for result, contending that expanding the traditional idea of quality to include the voice of the customer—through customer experience use cases—delivers the greatest improvement and provides the greatest return.

Solving High Tech’s Top Six Critical Business Issues (eBook)

A recent ebook from Tech-Clarity, “Solving High Tech’s Top Six Critical Business Issues,” reinforces what many in the high-tech product development world know: it’s a tough marketplace out there. New technologies offer exciting opportunities for innovation, but they also create implicit requirements for companies whose success depends on responding to ever-changing consumer desires.

This is a particular challenge given that lack of response to market trends could mean irrelevance and even obsolescence. In the drive to make connected, smart products, the pressure is on to be first or early to the market to capture share, but also to deliver something new and exciting for the market. We are all aware of products we once used that are no longer in existence. I was an early adopter of the PalmPilot (several versions), now they are nowhere. One study projects that 50% of the current S&P 500 will be replaced over the next decade. It happens to the best of them… Polaroid, Prime, DEC, Wang, just to name a few. No one wants that to happen to their company.

What are the critical business issues that organizations need to address to prepare for the future? Tech-Clarity identifies six:

1. Taking cost out

It is noted that 70% of a product’s cost gets locked in during the design cycle.  Are you using the right tools to fully optimize your design? Using a platform of simulation tools like 3DEXPERIENCE will help design teams fully assess a given design such as the best material, the ideal weight, the full load anticipated, hot spots on boards.  Identifying these characteristics early in the design process will play a significant role in designing right the first time before producing a prototype.

Top Engineering Challenges in High Tech Source: Tech-Clarity

2. Avoiding quality problems

One solution to this is creating a single source of truth for data management. In a separate study, Tech-Clarity found that 20% of time engineers are not working with the right data. This is a big issue for high tech who have mechanical, electrical and systems engineers working on the same project. Using a collaborative PLM platform that manages all product data will enable greater team efficiency and reduce quality issues down the line.

3. Achieving shorter product development schedules

Productivity gains rarely happen by maintaining current processes. When the right process changes get put into place, significant gains can be realized. Creating a collaborative design process ensures that all the teams have access to the right data when it’s needed. In high tech, a combined ECAD-MCAD platform is the key to bringing all the pieces together to shorten the design cycle and mitigate risks by putting the right checkpoints in place. Tech-Clarity identifies that 23% of the time engineers spend their time just “looking” for the right information. This gets even more time consuming when companies have multiple systems to check. A platform approach like 3DEXPERIENCE can remove these roadblocks and increase the throughput of all involved.

4. Facilitating innovation

Being nimble and agile is critical for high tech companies due to the rapidly changing needs of their consumers. Many design teams need to pivot off a current design but improve on it and create more interesting capabilities. Managing across engineering disciplines is critical for facilitating innovation and enables cross-pollination of ideas. Having an ideation repository can help spur new approaches to old designs along with a platform that manages data and other information in one place to support real-time collaboration.

5. Ensuring performance and reliability

Heat and vibration are the two biggest culprits that cause performance and reliability problems. It’s important to work with a team who has deep experience with electromagnetic simulation such as low-frequency applications such as electric motors to high-frequency applications such as sensors and antennas. There are many aspects to setting up multiphysics models correctly, never mind understanding the tools behind them. The good news is when you do work with experienced consultants (like Adaptive), we can help establish a testing and analysis process from concept through to final validation phases. Further, the process will also document and incorporate these tests into your design process so that you know why decisions got made and have access to the supporting data behind it.

6. Compliance with environmental and regulatory requirements

Consumers are hot on environmental-friendly products, and high-tech companies have the opportunity to work with materials that are recyclable and have better sustainability. Beyond pleasing consumers, high tech companies need to make sure they are in compliance with RoHS and other local regulations as it relates to their product life and obsolescence. A strong PLM platform can help ensure that the right steps are documented and signed off to meet compliance regulations.

Overall, the eBook supports an integrated platform for PLM to bring together ECAD and MCAD systems, the mechanical, electrical and system engineering teams and their design processes. A single version of the truth for data and contextual information (2D and 3D drawings) need to be accessible and a fundamental building block for any product lifecycle management (PLM) platform. Implementing tools that will not only enable but also promote and even require collaboration and virtual simulation, among other functionalities, will enable companies to overcome many of the unique challenges faced by the industry.
