In Part 1 and Part 2 of this three-part series, Mike Kuron discussed modeling techniques for printed circuit boards (PCBs), and thermal analysis of electronic components. In this final installment, I will address structural analysis of PCBs in terms of assessing their ability to survive vibratory load environments.
PCBs are used in most electronic products to mechanically support and electrically connect chips, capacitors, resistors, or other electronic components via soldered joints. Since many of these products will experience loading environments that include vibration loading, it is vital to determine the structural integrity of the PCB and its components due to these loads. This determination is often achieved using a random vibration finite element analysis.
The steps to perform a random vibration analysis of a PCB can be divided into three parts: Continue reading
As designs increase in complexity to cater to the insatiable need for more compute power spurred by different AI applications ranging from data centers to self-driving cars, designers are constantly faced with the challenge of meeting the elusive PPA (Power Performance and Area) targets.
PPA over-design has repercussions resulting in increased product cost as well as potential missed schedules with no guarantee of product success. Advanced SoCs pack more functionality and performance which result in higher power density. Traditional approaches of uniformly over-designing the power grid which has worked in the past is no longer an option with routing resources becoming severely constrained. To add to these woes, there are hundreds of combinations of PVT corners to solve for along with the increasing number of applications. Continue reading
Every new, smaller technology node developed in the semiconductor field has its own challenges, and the 7nm node is no exception. Usually a smaller technology node decreases price per transistor, but the cost benefits usually obtained from the smaller geometry are not as significant as in previous node changes. In fact, the increased complexity of lithography masks has made the unit cost per transistor slightly higher for 7nm devices. To offset these higher costs, products using 7nm semiconductors need higher margins, larger sales volumes and significantly higher performance than previous nodes. Achieving these goals requires designers to overcome a number of technical challenges, making upfront engineering simulation even more important than ever.
Semiconductors touch every aspect of our lives — from the computers that we work on to the automobiles we drive to the medical devices that keep us healthy. As these amazing chips become smaller and more packed with functionality (the latest NVIDIA graphics chip has 21 billion transistors!), designing and producing them becomes far more complicated. Yet increased demand for smaller, more powerful integrated circuits is increasing so companies can create the products of the future. Continue reading

According to Gartner, designing, testing and manufacturing 7nm FinFET-based system on a chip (SoC) requires massive resources: as much as $270 million and 500 man-years to bring the chip to market. Encapsulating such chips within a 2.5/3D package such as InFO-WLP improves power, performance and form factor while increasing the cost of design. To make a profit on that level of investment, the market for these chips tend to be high-end mobile and enterprise applications. To satisfy customer needs in these demanding markets, design teams have to deliver highly integrated devices that operate seamlessly and reliably for long periods of time. Additionally, you have to reduce the engineering time and cost, and ensure “first-time” working silicon. To do this you will need to move away from the traditional silo-based design flow to a chip-package-board co-simulation workflow and methodology. Continue reading
An automobile is the biggest and most complex connected device used by consumers today. Advanced driver assistance systems (ADAS) is one of the fastest growing automotive applications. Stringent government requirements on automotive safety, fuel consumption and technology-focused consumer preferences are fueling the growth of ADAS. Driven primarily by safety, ADAS capabilities were first implemented in premium vehicles as key differentiators to enhance the user experience and protect the vehicle and its occupants. It started with features like parking assistance, adaptive breaking systems (ABS), adaptive cruise control and tire pressure monitoring. Continue reading
Due to the volumes of data that need to be analyzed and the limits in simulation tool capabilities and processing power, sign-off in chip and electronic system design has traditionally followed a monolithic, margin-based approach that has resulted in larger die-size and longer development times. Today I’d like to tell you about a fundamentally new approach and software architecture called ANSYS SeaScape that will revolutionize chip simulation by harnessing the power of elastic computing, machine learning and big data to perform multiphysics simulations and design more compact, complex chips. This approach has demonstrated its ability speed up chip design and help eliminate many of the inefficiencies of traditional methodologies. Continue reading
