Many aspects of a PCB’s performance are determined during detailed design. Thermal issues with the PCB design are largely ‘locked in’ during the component (i.e. chip package)
- 10 Tips for Predicting Component Temperatures… A High-Level ‘How To’ Guide
Recently, physics-based reliability prediction has related electronic assembly failure rates to the rate and magnitude of temperature change over an operational cycle, both of which are influenced by steady-state operating temperature. Whether the intention is to increase reliability, or improve performance, accurate prediction of component temperatures helps meet design goals.
- 12 Key Considerations in Enclosure Thermal Design… A High-Level ‘How To’ Guide
A natural focus when designing electronics products are, well the electronics. The electronics itself however, needs to work within some kind of enclosure, and must be designed with the enclosure in mind. Cooling is a system issue, which is why we advocate a top-down approach, starting at the enclosure level.

- Disruptive New Serial-Interface; Intelligent Memory Architecture Jumps 100/400GbE Performance Wall
Packet processor design teams face increasingly difficult challenges as they seek to provide their network equipment manufacturers with state-of-the-art devices. The interrelated system-level trade-offs include performance, pin count, and area, and are all ultimately limited by power consumption considerations. To successfully compete, network chip vendors must consider end-to-end solutions for system architects and developers. In turn, as OEMs introduce multi-terabit systems, they must aggregate multiple 100 Gbps ports on each line card or risk falling behind the performance curve.

- Write Assist in Low-Voltage SRAMs
Write assist techniques are now commonly used to lower the minimum operating voltage (Vmin) of an SRAM. One of the key reasons to push the SRAM Vmin lower is to enable efficient Dynamic Voltage and Frequency Scaling (DVFS) to save power. In this paper, we discuss the basics of SRAM faliure mechanisms, fundamentals of write assist techniques, ARM® Artisan® Low Voltage Memory Compilers with the write assist feature and results from GLOBALFOUNDRIES 28nm-SLP memories.

- Enea Element®: Simplify Distributed Systems with Frameworks from Enea Element
Distributed systems range from simple multi-threaded applications to multi-slot chassis-based systems to networked clusters of servers. Topologies get more complex when these systems move into cloud-based environments, and more diverse when they involve machine-to-machine (or M2M) solutions. Providers of distributed system software solutions face a number of challenges in building, debugging and maintaining a set of connected applications. Managing these systems requires powerful modeling and a variety of management interfaces to meet a diverse set of needs. The services provided by a distributed system often require a high level of availability. The middleware frameworks that make up Enea Element address many of these challenges.

- VPX for High-Performance Avionic Computers
Traditional high-performance computing platforms are limited by the connection bandwidth and latency between the multiple computing elements needed to achieve the performance targets. For the embedded market, the difficulty is compounded by the demanding environmental requirements. The VPX standard resolves this limitation with a large number of high-throughput point-to-point connections between the processing elements in a rugged mechanical structure.

- LTE-Advanced Signal Generation and Measurement Using SystemVue
LTE-Advanced is specified as part of Release 10 of the 3GPP specifications and is now approved for 4G IMT-Advanced. This application note introduces key LTE-Advanced techniques, as well as how to use the Agilent SystemVue W1918 LTE-Advanced library to generate various downlink (DL) orthogonal frequencydivision multiple access (OFDMA) and uplink (UL) clustered DFT-spread-OFDM (DFT-S-OFDM) signal sources with MIMO, and to measure closed-loop throughput.
This application note also introduces LTE-Advanced enhancements to the MIMO channel models, which are available as simulation model set called the W1715 SystemVue MIMO channel builder. This optional model set facilitates simulation-based MIMO over-the-air (OTA) testing using real, observed antenna patterns and standard MIMO fading models, and overcomes a key challenge for 8-layer MIMO system analysis and verification.

- Best Practice Development Processes for Medical Device FPGAs
For FPGA developers working on designs for medical devices, one approach to dealing with regulatory uncertainty is to borrow heavily from design assurance processes in other safety-critical industries, such as avionics, where standards are well established. These well-established standards mandate a development flow that is controlled, auditable and perhaps most important, specific to the requirements of hardware engineering. While following such a flow will not guarantee smooth sailing though every regulatory approval process for FPGA devices bound for medical applications, it is consistent with basic regulatory intent - to demonstrate to auditors that complex devices meet their requirements and perform well under all foreseeable conditions.

- 10 Reasons to Customize A Processor Core
There are plenty of really good, proven processor cores on the market today. But if you have more than simple control tasks, perhaps you’ve considered using a processor that you can customize. We’ll give you 10 good reasons why you should consider customizing your core in your next SOC design.
- The What, Why, and How of Customizable Dataplane Processors (DPUs)
Designers have long understood how to use a single processor for the control functions in a SOC design. However, there are a lot of data-intensive functions that control processors cannot handle. That’s why designers design RTL blocks for these functions. However, RTL blocks take a long time to design and even longer to verify, and they are not programmable to handle multiple standard or designs.
