The focus of this paper is a combined electrical, thermal and optical characterization of power LED assemblies. Thermal management play important role in case of power LEDs, necessitating both physical measurements and simulation.

Many of the mysteries of equipment failure, downtime, software and data corruption, are the result of a problematic supply of power. There is also a common problem with describing power problems in a standard way. This white paper will describe the most common types of power disturbances, what can cause them, what they can do to your critical equipment, and how to safeguard your equipment, using the IEEE standards for describing power quality problems.

Controlling Automotive Electronic Emissions and Susceptibility with Proper EMI Suppression Methods

This white paper describes the use of CFD for LED lighting products. Thermal management is critical to LED performance and life so mechanical designers need to consider thermal issues from the earliest stages of the development process

This white paper explains the impact of the latest advances in CFD software that helps companies use CFD to improve product performance, reduce time to market, and lower engineering costs.

"As the number of enhancements to various Hardware Description Languages (HDLs) has increased over the past year, so too has the complexity of determining which language is best for a particular design. Many designers and organizations are contemplating whether they should switch from one HDL to another. This paper compares the technical characteristics of three, general-purpose HDLs.

This white paper discusses the many factors that affect the choice of the best EMI shielding materials for an application. These factors include: the materials used in the product's enclosure, the environment in which the product will be used, performance requirements for the shielding materials, quantity of products to be manufactured, and the preferred installation equipment.

A powerful signal integrity analysis tool must be flexibility, easy to use and integrated into an existing EDA framework and design flow. In addition, it is important for the tool to be accurate enough. This report reviews a validation study for the Mentor Graphics HyperLynx 8.0 PI tool to establish confidence in using it for power integrity analysis.

For advanced signaling over high-loss channels, designs today are using equalization and several new measurement methods to evaluate the performance of the link. Both simulation and measurement tools support equalization and the new measurement methods, but correlation of results throughout the design flow is unclear. In this paper a high performance equalizing serial data link is measured and the performance is compared to that predicted by simulation. Then, the differences between simulation and measurements are discussed as well as methods to correlate the two.

High Density Interconnect (HDI) is being used more often to meet the growing need for more complex designs in smaller form factors. Beyond some of the more obvious electrical effects of using smaller vias, there is also an impact to the power integrity of a board using HDI. This includes different effects of mounted inductances of decoupling capacitors, changes in plane performance due to reduction in perforation from chip pinouts, and the inherent plane-capacitance changes from using dielectrics of various thicknesses. This paper will examine and quantify these effects, using numerous design examples, including a large conventional through-hole design board that was reduced using HDI.

The success of any consumer electronic device depends to a large extent on the appeal of the user interface (UI) and how easy the device is to use. Studies show that good cosmetic design can encourage users to explore the full range of features and often engenders the perception that a product is easier to use. So if the benefits of a great looking, easy-to-use UI are so clear, why are so many products still falling short of customer expectations? The solution lies in taking a fresh new approach a consumer electronic device UI plays. By identifying common UI functionality and implementing it in a reusable and customizable way, we can make it far easier for embedded engineers to deliver visually engaging and easy-to-use consumer electronic products.

Moving to C++ presents opportunities for higher programmer productivity. The requirements of embedded systems, however, demand that the adoption of C++ be carefully measured for the performance impact of run-time costs present in C++, but not in C. This talk suggests strategies for developers who are starting their acquaintance with C++.

To accommodate increasingly dense technology environments, increasingly critical business applications, and increasingly stringent service level demands, data centers are typically engineered to deliver the highest-affordable availability levels facility-wide. Within this monolithic design approach, the same levels of mechanical, electrical, and IT infrastructure are installed to support systems and applications regardless of their criticality or business risk if unplanned downtime occurs. Typically, high redundancy designs are deployed in order to provide for all eventualities. The result, in many instances, is to unnecessarily drive up both upfront construction or retro-fitting costs and ongoing operating expenses.

Electronics and Software Engineering are quickly merging with traditional Mechanical Engineering to create a new paradigm in auto manufacturing: Mechatronics. Industry experts predict that this shift will bring about profound advances in automotive product development. Unfortunately, existing IT and process infrastructures do not provide sufficient capabilities to support the new paradigm: multiple data silos, a lack of standardized processes, and integration issues on a tool level (Mechanical, Electronic, Software) continue to pose serious obstacles to development efficiency, and remain a frequent source of delays, quality issues and cost increases.
