"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.

Find out how a robust configuration audit and control system can enable electronic submissions and signatures, and validate electronic data, in compliance with the FDA's mandatory submission of clinical trials records.

No question the UI in electronic devices today is playing a larger role in the success of a device. Get the UI wrong and your product will have little chance of surviving. And it isn’t enough to deliver a UI that is merely functional: it has to look good too. Studies have shown that a good cosmetic design can encourage users to explore the full range of features and often, can engender the perception that a product is easier to use, which can make consumers more tolerant of product deficiencies.

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++.

When Alcatel bought out Lucent at the end of 2006, the two companies had already begun planning data center consolidations of their own, but the merger changed all that. As it turns out, the merged company created a plan to consolidate 25 data centers and 125 server rooms down to six data centers and just a few server rooms. This change has presented challenges, especially in terms of arranging downtime and dealing with employees' attachment to their servers and applications, but the company is on pace to meet it’s goal of reducing IT operational cost by 25% over three years.

Uninterruptible Power Solutions are often solved at the facility level with unnecessarily large, inefficient, expensive and complex AC UPS systems. While this provides an easy demarcation line between the facility and end equipment, with each focusing on a different part of the problem, it also results in overall operating efficiency and total cost of ownership being difficult to ascertain and optimize.

Modern Electronic Systems are quite often powered from a three-phase power source. While utilizing power modules that operate directly from three-phase power might seem to provide optimal simplicity and flexibility, the added complexity required to realize three-phase power factor corrected circuitry usually negates any potential savings.

Dell servers have been optimized to help provide strong support for the latest ESX release, VMware ESX 3.5 Update 2, including enhanced performance for virtualized environments based on support for six-core Intel Xeon processors. Organizations that do not approach server virtualization with a clear plan risk developing a chaotic, inflexible infrastructure that wastes energy and resources.

Find out how each aspect of perfect order performance (On-Time Delivery, Complete Orders, Damage-free Delivery, Accurate Invoicing and Documentation) can be improved through enhancements to data collection processes and technologies including RFID, speech, imaging technology, and GPS.

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.

PTC, the Product Development Company® today announced that Samsung Electronics Co., LTD (SEC), a leading digital products manufacturer of mobile phones, televisions, and semiconductors, has selected PTC Windchill as its digital product development data repository to manage an integrated BOM of mechanical, electrical and software data across its globally distributed product development environment. Windchill is the standard enterprise PLM solution at SEC because of its powerful, Web-based support of key product development processes on a single technology architecture and execution environment.

Using digital control in power supplies is considerably more flexible than analog control in its ability to adapt to changes and digital control inside the power supply results in advantages to the system application such as improved efficiency, fewer external components and reduced overall cost.
