Modern high-tech products using chips that are designed with the latest deep sub-micron process technologies (28nm and below) and FinFET technology offer higher performance, smaller footprint and lower power. However, power integrity analysis and reliability challenges become increasingly complex for chip package designs using these devices.
More stringent manufacturing rules present basic layout challenges and new design innovations require careful consideration of effects such as electromigration (EM), electrostatic discharge (ESD) and noise coupling through substrate, signal and power rails. Even the most thorough sign-off process can often fail to prevent tape-out hurdles or extensive redesign. Therefore, forward-thinking design teams need to address reliability and power integrity long before final sign-off, accounting for their impact during the design process itself. Continue reading →
“A picture is worth a thousand words.” Pictures, or model-based designs, as engineers refer to them, provide a natural means of communication. With the newest release of ANSYS SCADE System 15.2, systems engineers can use models and interface control documents (ICDs), rather than text files and long lists of data, to create and manage their systems designs.
However, when precision and complexity come forth, “data dictionaries” enter the game. A dictionary is a way to manage information in an exhaustive way but without the model, it’s not easy to get an overview of your system. The issue you’re then faced with is the consistency between the model and the dictionaries — if inconsistent, the situation is worse than without the model. Continue reading →
The U.S. Environmental Protection Agency (EPA) recently released new Corporate Average Fuel Economy, or CAFE standards for light duty cars and trucks. These standards are designed to reduce greenhouse gas emissions and improve fuel economy, leading to model year 2025 vehicles that will emit just one-half the greenhouse gasses that model year 2010 vehicles do.
To reach these ambitious goals, the new CAFE standards mandate that automakers raise the average fuel efficiency of new cars and trucks to 54.5 miles per gallon by 2025. These are lofty and commendable goals. But for engine designers and automakers, are the new standards even feasible for real-world vehicles? The EPA believes they are, and has established a new program to prove it. Continue reading →
The aircraft industry is an exciting place to be today. The media is full of the potential for commercial drone applications. But in the here and now we have large commercial aircraft on the market made from over 50% composite materials. These aircraft represent decades of innovation and will make a significant and positive impact on lifecycle cost of operation and the environment. You may recall that we recently shared a case study from Terrafugia where they discussed the integration of composite materials into the airframe of a car-come-aircraft. Along similar lines, EADS Innovation Works have shared details of their experiences with ANSYS composite material design tools. Continue reading →
Multiphysics simulation is increasingly important in the design of products and processes. This is because, in the real world, it can be costly if you don’t consider the impact of all the physical forces. Reliability and performance of your product could depend on it. Even if you ultimately determine that the impact is minimal, you have to take into account both the consequence of each potential physical force and how it interacts with other forces before performing further analysis or dismissing the effect. The questions you ask and the problem you attempt to solve determine what simulation technology is required to uncover the answers. Is just one force dominant or is the interaction between several physics the key to design? In the most recent issue of ANSYS Advantage magazine, engineers from several industries ask these questions ― and determined the best answer can be obtained by using multiphysics simulation.

For several years, I have seen engineers working in the industry or finishing their degree in engineering that have been looking for advanced education in ANSYS.
Some of them were unable to find a course with enough specialization, without the restrictions of classroom training, or with certified content from ANSYS.
Now, the Technical University of Madrid (UPM) has responded to this request by organizing, in collaboration with ANSYS, an online master’s degree with the goal of training experts in fluid mechanics and solid mechanics numerical simulation using ANSYS engineering tools. Continue reading →
I enjoy working on every article I coordinate for ANSYS Advantage magazine. I always learn something new while assisting ANSYS customers and staff tell their stories of excellence in engineering simulation. I have no favorites as I appreciate all of the articles. But, I decided to let our readers choose their top five, based on the power of downloading. The following are the most-read articles from the four issues (three regular issues and one special issue for oil and gas) of ANSYS Advantage published last year. All these stories have one thing in common: They feature robust and reliable design practices. Drumroll please …
