Understanding Grounding
Misunderstanding how ground is implemented in circuit simulation is one of the most common misuses of electromagnetic (EM) simulators and their results. This white paper discusses the defi nition of ground in EM simulators and how to correctly choose among various grounding options, a topic of special importance to designers using the results in a circuit simulator. Many modern simulators now support the notion of local grounding, where different ports can use different ground defi nitions. New features in AWR’s AXIEM™ 2009 3D planar EM simulator offer extensive sources/ports and de-embedding options, including internal edge, fi nite difference/gap and extraction ports, and per-port, coupled line and mutual group de-embedding.

A Plethora of Ports:
Electromagnetic (EM) simulation technology software has come a long way since it first became popular for microwave and RF circuit design back in the 1980s. With the sophistication of today’s EM tools, it is sometimes difficult to remember how limited those early simulators were. The author is old enough to remember when a challenging problem for a 3D planar simulator consisted of a coupled-line filter with 1000 unknowns and 3D finite element simulators were stressed by a simple multi-layer via transition in a package.

A Basic Mathematical
Electronic Design Automation (EDA) has been one of the great enabling technologies for modern electronics, including the class of analog circuits classified by their operating frequencies: RF/wireless, microwave, millimeter-wave, etc. Initially distinct and discrete software tools were developed for (logical) circuit simulation and (physical) layout, and these were later augmented by physical verification (DRC & LVS), system simulation, and electromagnetic analysis (EM). Later still, all of these tools came together under unifying environments providing a common database and standardized graphical (schematic) entry. AWR Corporation

High-Speed Serial Backplane
The benefit to having high-frequency design tools resident on a Vector Network Analyzer (VNA) does not become obvious until the time comes to compare simulation to measurements. At this point, the advantage of a more streamlined work flow -- without the impediment of transferring data to a simulator running on a separate PC or workstation - becomes clear. To illustrate the benefit of such a novel, integrated solution (AWR’s Microwave Office software “inside” the Anritsu VectorStar VNA), this application note follows the design flow for a high-speed serial backplane.

Clock and Reset Ubiquity:
Today’s SoC integrates a collection of peripherals, memory, graphics, networking and I/O components that originate from a multitude of sources. It could comprise designs from within the company, from other companies or from third-party IP vendors. These independently developed components come together to enable a rich feature set for the SoC. However, accompanying this abundance of features is a significant amount of complexity that needs to be correctly and efficiently handled to render the integration successful. One such source of complexity is that components operate at clock frequency ranges that may be very different from those of their counterparts. The existence of these multiple clock domains and the need for them to exchange information creates a hotbed for CDC bugs to thrive. As a result, CDC verification becomes critical to ensure that metastability is not introduced in the design. In this article, we provide several situations with varying set of examples that showcase the challenges in CDC verification. Real Intent, Inc.

AWR's Support of Polyharmonic
Linear and nonlinear device models are the building blocks of most RF and microwave designs. S-parameters are often used to represent linear devices. As a “black-box” model, they can easily be obtained using a vector network analyzer and distributed for simulation. S-parameters use superposition to equate the linear relationship between incident and refl ected waves at all of the device’s ports. Nonlinear devices, however, distort waveforms such that their behavior cannot be represented through superposition or S-parameters. AWR Corporation

Design and Optimization
3D electromagnetic (EM) simulators are commonly used to help design board-to-chip transitions. AWR now makes life easier for circuit designers with the introduction of Analyst, a full featured, 3D EM fi nite element method (FEM) simulator. The key advantage of Analyst over other available 3D simulators is its tight integration within the Microwave Offi ce® design environment, AWR’s circuit design and simulation platform. This application note highlights the unique features of Analyst by demonstrating the optimization of the transition from a board-to- -chip signal path. The example shows how the ability to access Analyst from within in the Microwave Offi ce environment saves designers time and provides ready access to powerful layout and simulation tools that are not available in typical circuit design tools.

Synthesizing & Optimizing
Like all RF and microwave components, a distributed filter design will remain only a simulation exercise if it is not created with its manufacturing process in mind. That is, the tight dimensional tolerances required to meet a set of performance goals must be within the capabilities of the filter’s manufacturing process in order to realize a reliable, repeatable filer AWR Corporation

Leverage Circuit Envelope
Moving to next-generation cellular systems requires new levels of performance from RF power amplifiers (PAs). While designing PAs has always included the challenge of maximizing efficiency while delivering high linearity, never have the tradeoffs been so difficult as they are for 4G/LTE. For instance, the latest higher-order modulation schemes require exceptional linearity throughout both transmit and receive signal paths, yet wireless carriers demand the highest possible efficiency at the system level. AWR Corporation

Exactly How EM Should
Modern RF/microwave design flows make extensive use of electromagnetic (EM) analysis in many ways, and its co-existence and concurrency with circuit design and analysis can not be underestimated. Prior to the circuit design and especially in larger designs, EM tools are used to create “library” parts such as inductors, transitions, and antennas. While these parts are fairly self-contained, they must ultimately be integrated into the overall design where at the very least they must be connected to the rest of the circuit or in a more complex case be coupled to it. During both early and later stages of design, designers will switch from circuit-based models to EM analysis of critical interconnects to better understand couplings and achieve greater accuracy. EM analysis is used again before the design goes to manufacturing, so that the metal in the design can be analyzed one more time to verify circuit performance alongside design rule check (DRC ), layout versus schematic (LVS), and even design for manufacturability.

Understanding and Correctly
Understanding and correctly predicting cellular, radar, or satellite RF link performance early in the design cycle has become a key element in product success. The requirements of today’s complex, high performance wireless devices are driving designers to assess critical measurements—noise fi gure (NF), 1dB gain compression (P1dB), third order intermodulation distortion versus output power (IM3dBc), and signal-to-noise ratio (SNR)—long before manufacturing begins. Traditional modeling methods such as rules of thumb and spreadsheet calculations (Friis equations) give limited insight on the full performance of an RF link in next-generation wireless products. AWR Corporation

ACE - Automated Circuit
The Traditional approach to RF/MW circuit design – which is the present day foundation for high-frequency wireless design applications – is being pressured simultaneously by an increase in operating frequencies / bandwidth and a decrease in physical footprint size. The result is that the physical design challenges faced by circuit designers are rapidly increasing, while choices for how these challenges should be best-addressed are not. AWR Corporation

Understanding Available
RF system-in-package (SiP) and multi-chip-module (MCM) designs present engineers with the challenge of integrating complementary metal oxide semiconductor (CMOS) integrated circuits (ICs) for digital circuits and gallium arsenide (GaAs) or silicon germanium (SiGe) devices for RF and microwave circuits with soft-board laminates and low-temperature co-fi red ceramic (LTCC) packages. Software used to design these complex circuits must seamlessly bring together synthesis, simulation, and verifi cation solutions via a single interface in order to ensure optimum component design and placement in each technology. It must also construct schematics and perform physical design entry for any technology in the SiP using uniform commands and menu options. AWR Corporation

The Advantages of Multi-rate
Harmonic balance (HB) analysis is a method used to calculate the nonlinear, steady-state frequency response of electrical circuits. It is extremely well-suited for designs in which transient simulation methods prove acceptable, such as dispersive transmission lines in which circuit time constants are large compared to the period of the simulation frequency, as well as for circuits that have a large number of reactive components. In particular, harmonic balance analysis works extremely well for microwave circuits that are excited with sinusoidal signals, such as mixers and power amplifiers. AWR Corporation

Visual System Simulator
Achieving the highest possible performance from circuits used in third-and fourth-generation wireless systems is driving a tighter integration of previously disparate tools. Certainly, a level of software synergy is essential when designing circuits for use in today’s wireless systems that employ higher-order modulation techniques together with advanced technologies, such as Orthogonal Frequency Division Multiplexing (OFDM), multiple-input multiple-output (MIMO) and digital predistortion (DPD) circuits, to name a few. As this white paper illustrates, AWR’s Visual System Simulator (VSS) and National Instruments’ LabVieW graphical programming nvironment are now co-simulating so as to better enable designers to analyze, optimize, and verify complex RF circuits, subsystems and digital signal processing within a unified framework. AWR Corporation

Steady State and Transient
Thermal effects in electronic devices are studied to investigate their influence on reliability and electrical performance. Due to the decreasing size of semiconductor devices operating at unchanged power levels, thermal analyses provide circuit designers with important information about device degradation and electro-thermal coupling. Steady state thermal analyses have been performed for many years in electronics reliability engineering to evaluate device lifetimes. Device channel temperature is the most critical parameter to determine in such a reliability study as it is the primary source for thermal degradation mechanisms. Many techniques exist for modeling and measuring device channel temperatures, however large discrepancies are reported in the literature [1]. AWR Corporation

Upfront RF Planning Speeds
High-frequency technology didn’t earn its reputation as black magic for no reason. Unlike low-frequency circuits, microwave circuits don’t behave in a totally predictable way, so “tweaking” has been an accepted mainstay of the microwave design approach/fl ow. Fortunately, high-frequency design tools have dramatically improved so that tweaking of prototype circuits is much less common, and today’s engineer has powerful tools that can make sense of the black magic.

How to Optimize an LTE
Long Term Evolution (LTE) is rapidly being deployed by major US carriers and will serve most, if not all, top-tier markets some time during 2012. LTE is often called a fourth-generation (4G) standard, and provides signifi cantly increased peak data rates, with the potential for 100 Mbps downstream and 30 Mbps upstream, reduced latency, scalable bandwidth capacity, and backwards compatibility with existing Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) technology. AWR Corporation

Improved Circuit Design
To fi ne-tune an RF/microwave design to meet new design criteria, engineers turn to the built-in optimizers within their electronic design automation (EDA) software. A typical optimization case for a microwave filter, for instance, might include goals for in-band insertion loss and return loss, cutoff frequency, and out-of-band rejection. The large number of criteria that the optimization engine then has to take into consideration to create a landscape of “solutions” are more or less random, and, more often than not, quite large.

Using LabVIEW in the
Many veteran designers no doubt remember how comparatively simple it was to design base station or mobile phone amplifi ers when the only modulation technique was analog and amplifi er performance could be verifi ed using Additive White Gaussian Noise (AWGN). Nowadays, second (and subsequent) generations of wireless networks usher in digital modulation techniques that necessitate the need to stimulate amplifi ers and other circuits with waveforms they actually process in service. It therefore necessitates far tighter integration between the baseband signal processing and high-frequency circuit design tools as well as actual test equipment for both generating these modulated waveforms and evaluating their effects on the performance of the design. AWR Corporation

Hardware in the Loop:
When simulating a complete subsystem such as a wireless communication device or radar receiver, the quality of measurement data becomes essential to ensure that the fi nished product meets or exceeds the demands the system will encounter in service. The measurement data can be used to make changes to the system early in the design process, when those changes can be realized in the least amount of time and at the lowest cost. However, this can be accomplished only if there is a direct link between the system being simulated and the measurement equipment itself—that is, when there is “hardware in the loop.”AWR’s Visual System Simulator™ (VSS) combined with its TestWave™ software provides an end-to-end communications system simulation environment that makes this possible.

Using Visual System Simulator
The concept of software defined radio (SDR) has existed for many years. Consequently, you can find many descriptions of an SDR. A concise definition of an SDR is a radio in which some or all of the physical layer functions are software-defined. The physical layer function is the layer within the wireless protocol in which processing of RF, IF, or baseband signals (including channel coding) occurs. Many of today’s SDRs have part of the signal processing implemented in software. AWR Corporation

End-To-End System Design:
Architectural tools used by designers of RF and microwave communications systems include budget simulators, spur searching utilities, and frequency planning tools, all of which are often based on spreadsheets or hard-coded algorithms with a non-commercial user interface. Having served designers well, these “home brew” approaches are limited in functionality and/or breadth, unsupported, and are as varied as the designers who create them. While the level of effort to create these tools was great and once acceptable (if only because there was no suitable alternative), few designers today have the time required to build their own design utilities nor massage existing legacy ones to meet growing requirements of today’s communciation systems. This white paper outlines the benefi ts of using a commercial, specialized software program, such as AWR’s Visual System Simulator™ (VSS) software for end-to-end system design, while also embracing legacy approaches with the incorporation of spreadsheet views.

Integration of Signal
The system supports easy design in cooperation with test and simulation processes using a signal analyzer/vector signal generator, as well as effective optimization of RF components and overall system performance. Using simulation based on actual measurement data reduces the amount of design and prototyping work, cutting R&D time and costs. Moreover, it can help match performance to requirements, preventing over-specification waste and cutting product costs. AWR Corporation

Challenges in Verification
Emerging systems have three dimensions of complexity when it comes to making them CDC-safe. First, the number of asynchronous clock domains in designs can range from the tens to the hundreds for complex systems with many components. Second, the master clock frequencies vary per component. It is not uncommon for the ratio between the fastest and the slowest clocks to be greater than 10. Third, the clock frequencies themselves can change dynamically during the course of chip operation to save power. As a result, CDC verification becomes critical to ensure that metastability is not introduced in the design.

This article provides several situations with varying set of examples that showcase the challenges in CDC verification.

X-Propagation Woes: Masking
This paper presents a complete and practical methodology to comprehensively solve the X problem in RTL design. It begins by reviewing common sources of Xs, and describes how they cause functional bugs as well as unwarranted debug that prolong verification cycles. Solving the X problem helps minimize simulation and synthesis iterations and enables various design analyses (e.g. power analysis), normally performed on netlists, to begin sooner. The pros and cons of various point solutions to this problem are described. The technologies discussed include structural analysis, formal analysis, coding for X-accuracy, and simulation techniques such as random seeding of state initial values. It is essential that a complete solution address both X-optimism and X-pessimism woes as well as be applicable to all sources of Xs, facilitate debug, provide coverage analysis, and enable automation, high performance, and usability. The requirements of a complete and practical solution, based on feedback from users who deal with X issues are provided. The summary of our interaction with users is that the X problem is multi-dimensional and needs a holistic solution that brings to bear the combination of structural analysis, simulation and formal analysis to solve effectively. We describe our user experiences and a case study based on our proposed solution. Real Intent, Inc.

Analyzing Power Integrity
When a printed circuit board (PCB) includes a power plane that is near to signal traces or other power planes, there is a significant risk of energy transfer between parts of the system. Not only does this coupling lead to power switching noise being transferred into data signals, it also means that power supply systems may demonstrate additional resonances that are not seen in the individual components. This can affect the power integrity of the PCB and may reduce its speed or reliability. This paper will explore some of the potential power integrity issues that can affect a PCB and explain how simulation can be used to help reduce these effects. CST-Computer Simulation Technology

I am struck at how easy it is to get used to “good enough” ways of working. Often we fail to notice new innovations that can make our tasks easier and boost our productivity and reduce risk to success.

Cadence EDA360 Vision Paper
Today, systems and semiconductor companies are undergoing a disruptive transformation so profound that even the best-known companies will be impacted. The EDA industry now stands at a crossroads where it also must change in order to continue as a successful, independent business. The disruptive transformation we are speaking of is not about EDA developing new design tools. It is not about new methodologies. It is not about the functional verification crisis, or the move to electronic system level (ESL) design, or any of the issues that have dominated discussions about EDA to date. It is about something much larger. It begins with a shift from design creation to integration in the electronic systems industry, and results in a new focus on profitability. This realization, in turn, opens the way to EDA 360, a new vision for what the EDA industry can become. Cadence Design Systems, Inc.

A New Method to Improve
Tomorrow's memory standards hold the promise of higher performance. With the uncertain future of which protocols will emerge as industry standards many system architects conservatively choose from current DDR standards - adopting a "wait and see" approach. However, the needs to improve system performance and reduce power consumption are still paramount with next generation products. With memory subsystems representing significant influences on these two areas, designers must find new methods to improve the performance of memory sub-systems. The Performance-IP method discussed here is implemented using small, distributed, logic elements requires no code changes and does not require the increase of system clock rates. Performance-IP LLC

Ways of Bypassing CPU
Direct Memory Access (DMA) is one of several methods for coordinating the timing of data transfers between an input/output (I/O) device and the core processing unit or memory in a computer. DMA is one of the faster types of synchronization mechanisms, generally providing significant improvement over interrupts, in terms of both latency and throughput. An I/O device often operates at a much slower speed than the core. DMA allows the I/O device to access the memory directly, without using the core. DMA can lead to a signifi-cant improvement in performance because data movement is one of the most common operations performed in processing applications. There are several advantages of using DMA, rather than the one in which core does a memory to transfer operation and vice versa and this paper discuss all these advantages with various applications of DMA Controller. DMA is used in almost every complex system or subsystems , but its observed that teams either build the DMA controller from scratch for each project for specific application or take the existing DMAC available from elsewhere. Here in this article I have tried to discuss the architecture of DMAC that can be used with any kind of Bus, configuration (parallel, serial transfers), can be connected to any kind of ports, most importantly any kind of software assumptions can be implemented in the DMAC very easily. I call it Universal DMA Controller. MindTree Ltd

Is it time to switch
Six years ago, when OASIS was introduced, we published an article highlighting why it was a positive replacement for GDSII [1]. Since then, users have started adopting OASIS in their flows, with benefits and disadvantages. One of OASIS strengths is its flexibility (unlimited coordinate precision, unlimited number of layers, etc...). But this flexibility has a price in terms of memory consumption and computing time. A new standard, OASIS.MASK, is being introduced to address the requirements specific to photomask layout repre- sentation. This subset of OASIS (and as such fully OASIS compliant)introduces constraints that reflect the real-world limitations of mask manufacturing. As a result, OASIS.MASK interpretation and exploitation is more efficient and reliable. [1]P. Morey. Going from gdsii to oasis. EEtimes, December 2008. Xyalis

The ROI of Hardware Configuration
Software teams have long realized the return on investment (ROI) of software configuration management (SCM) systems, which have been used by software teams for decades to manage development, improve collaboration, and coordinate releases. In fact, SCM systems have become such an integral part of a software development environment that practically no significant software project is even started without a SCM methodology in place. Over the last decade, hardware design teams have encountered the same market forces as software designers: increased competition due to globalization, mandating the use of the best available engineers irrespective of location; an exponential increase in design complexity; and shrinking market windows. The result has been larger teams of engineers spread across multiple sites, managing complex flows, and sharing a large volume of constantly changing data. They need hardware configuration management (HCM) systems. Cliosoft, Inc.

New Approach to Accelerating
Despite many efforts to automate analog design and layout, these tasks remain primarily a full custom process, ; with the result that analog is occupying a larger and larger portion of the total design cycle time. Efforts to automate analog design have not been successful in the marketplace because the tools have not been able to equal the quality levels of full custom design, are complex to set up and use, and are expensive. Tanner EDA’s new tool forgoes full automation in favor of accelerating the layout process by generating key analog design primitives, such as current mirrors and differential pairs. These primitives are often the most time-consuming aspect of layout and indeed the parts that are critical to the functionality of the silicon. The new tool applies matching techniques to address common processing artifacts, produces the optimal solution for parasitics and silicon area, and creates devices optimized for high yield.

Matching Circuit Optimization
Impedance matching is an essential part of antenna design. The input impedance of an antenna needs to be reasonably close to the amplifier impedance (e.g. 50 Ohm), otherwise the signal is reflected back to the amplifier and not radiated by the antenna. In many applications matching circuits consisting of discrete inductors and capacitors, or transmission lines are used to improve the impedance matching characteristics of the antenna. This white paper discusses the optimization of matching circuits especially to antenna applications. Although the design of matching circuits sounds simple, there are many practical considerations that need to be addressed. CST - Computer Simulation Technology

Design and Verification
We propose a new methodology flow which will allow the visual definition of a complex SoC through instantiation of parametric IP such as processors, SDRAM controllers, DMA engines, on-chip buses, peripherals, switch matrices and coherency directories, coprocessors, etc. Script based automation helps in integrating any IP with any configurations ,selects relevant and corresponding Verification IPs(in-house developed-if Design IPs are standard), uses suitable Bus Wrappers(OCP,EBI,Avalon,MicroBlaze,PicoBlaze,PIF,AXI,AHB,APB,Generic and others) and stitches all the components design as well verification(synthesizable testbench components ) together and making use of TLMs,BFM (replacing CPUs with Master BFMs) or Process Core based designs creates an CSOC environment.

DesignWare SATA AHCI
This application note describes how to configure and connect the DesignWare® SATA AHCI IP core to the Synopsys PHY in a multi-port AHB-based configuration, and provides an analysis of the expected throughput on each port based on assumed system parameters. The expectation is that a user should be able to take this example and insert actual system parameters to come up with a performance estimate. We will look briefly at the architecture of the core to enable a better understanding of the subsequent sections describing the configuration and performance calculations of the core. Also, note that while this document only discusses the performance of an AHB-based configuration, the option to select an AXI-based configuration will be available in the near future. Due to the nature of the AXI-bus, which allows for overlapping transfers, we expect an increase in the performance of a multi-port configuration. Synopsys Inc.

Invarian Addresses Sign-Off
IC designers responsible for the physical implementation of the design face a huge problem of design sign-off analysis. Today, they need to use different tools to verify the various design aspects, such as timing, power, voltage drops, and chip temperature. The problem is that each of these analyses needs the results of all the other analyses. Therefore, typically, these tools are run sequentially in a flow, so that the results of one tool can feed the next tool. Invarian

Facilitating Unreachable
Code coverage is a popular method to find design bugs and verification loopholes. However, once a piece of code is determined to be unreachable, diagnosing the cause of the problem can be challenging: since the code is unreachable, no counterexample can be returned for debugging. Therefore, engineers need to analyze the legality of nonexistent execution paths, which can be difficult. To address such a problem, we analyzed the cause of unreachability in several industrial designs and proposed a diagnosis technique that can explain the cause of unreachability. In addition, our method provides suggestions on how to solve the unreachability problem, which can further facilitate debugging. Our experimental results show that this technique can greatly reduce an engineer’s effort in analyzing unreachable code. Avery Design Systems, Inc

Timing efficient cell
Pin multiplexing is a common practice applied in order to save large number of pads in an SoC. This reduces the Die area of the chip but impose a number of limitations, like requirement of dedicated, complex pin muxing circuit. Traditionally there are three major types of pin multiplexing circuits which are in use; arbiter based , resgister configurable and priority muxing . Out of these , priority muxing simplifies the muxing strategy as it muxes the various functions together on the basis of timing criticality , also it utilizes the IP’s in built select signal . In this paper we propose a novel MUX cell design which can be applied at the places where priority muxing is used. This muxing strategy enables muxing of functions with equal timing criticality together at one single pad even with the priority intact. Which in turn limits the number of high driving pads in SoCs hence saving power and area both? The proposed circuitry is technology independent and also saves area . This circuit is applied in a SoC at 90nm technology by replacing traditional priority based pin muxing and almost 72% area saving and significant interface frequency increase is achieved Freescale Semiconductor

Finding Reset Nondeterminism
Due to increases in design complexity, routing a reset signal to all registers is becoming more difficult. One way to solve this problem is to reset only certain registers and rely on a software initialization sequence to reset other registers. This approach, however, may allow unknown values (also called Xvalues) in uninitialized registers to leak to other registers, leaving the design in a nondeterministic state. Although logic simulation can find some X-problems, it is not accurate and may miss bugs. A recent approach based on symbolic simulation can handle Xs accurately; however, it is not scalable. In this work we analyze the characteristics of X-problems and propose a methodology that leverages the accuracy of formal X-analysis and can scale to large designs. This is achieved by our novel partitioning techniques and the intelligent use of waveforms as stimulus. We applied our methodology to an industrial design and successfully identified several Xs unknown to the designers, including three real bugs, demonstrating the effectiveness of our approach.

Derating of Schottky Diodes
Schottky diodes use a metal-semiconductor junction as opposed to the semiconductor-semiconductor junctions used in standard diodes. This configuration allows for lower forward bias voltage drops (0.15V - 0.45V vs. 0.5-0.7V) and faster switching times, making them ideal for power supply switching operations. Drawbacks for schottky diodes include much higher reverse bias leakage current ratings. Because p-n recombination is not a factor in switching delay time, only capacitance affects the reverse switching time. DfR Solutions

An Introduction To Property
The increasing complexity of system-on-a-chip and ASIC designs has caused an ever-widening gap between what can be designed and what can be. It is estimated that between 50-70% of the time required to design a complex IC is spent in verifying that the functionality of the system is correct. Bugs in a design are least expensive to fix just after they are created. At this stage the design is still fresh in the designer's mind and other parts of the project or other design team members are unaffected. Bugs are at least an order of magnitude more expensive to fix during system integration. In this phase it takes more time and people to analyse the cause, regression tests must be rerun, and the entire group may be delayed. These challenges are giving rise to some exciting new tools and approaches in Verification techniques. Averant

"You could say the library is the brain of our development. All the information our developers need for their work is stored centrally, so they know, for instance, whether they can use a component for a new development or when it has been discontinued” Lutz Napiwotzky, responsible for Engineering Applications Corporate IT at Bosch. When the Bosch Group’s Automotive Technology Division, one of the world's leading suppliers to the automotive industry, analyzed their development processes, they quickly identified areas for improvement, including consistent data management. Each division structured data differently and stored it in different systems. As a result, tasks like tracing component use were inefficient and sometimes impossible. After implementing Dassault Systèmes’ 3DEXPERIENCE platform Bosch engineers understand exactly which components were installed in which devices, including all configuration and material information. In particular, the component library structuring and versioning capabilities bring significant value to the Stuttgart-based company. Dassault Systèmes

Generating multiple types of manufacturing outputs helps widen the path to PCB manufacturing. Lastly, providing the fabrication vendor with accurate design data can directly improve product quality.

Robust System Thermal
Today, process technology has advanced to 32nm, resulting in an increase in the number of transistors per unit area and a reduction in package size. At the same time, system designers are trying their best to reduce the system size by increasing the component density on boards, adding as many features in the design as possible to deliver the industries’ best products in terms of space and size. Increased transistor density inside the chip, higher operating speeds, and increased component density on board in modern electronic systems has led to relatively more heat being generated in these systems. All this has made thermal management an integral and critical part of system management in all application domains, including automotive, industrial control, consumer electronics, battery powered systems, and so on. Many systems are equipped with cooling fans to deal with the heat generated. This has led designers to realize the need to come up with cost-effective, reliable, noise-free, and power efficient temperature-based closed loop fan control systems. Cypress Semiconductor Corp.

Reducing EMI in digital
Over the past couple of decades, more and more applications are going digital. Implementation of digital systems is very simple as it is entirely about logic; however, complexity increases exponentially with signal speed, specifically clock synchronization, setup and hold time, jitter, and so on. These problems affect the functionality of not only the individual subsystem but also cause electromagnetic interference (EMI) when high frequency devices are operating in close proximity. Figure 1 shows a typical example of EMI caused by a DVD player on TV reception. Cypress Semiconductor Corp.

Tunable White Light
Undoubtedly, color plays a significant part in our perception of the world around us. We have often experienced situations where the same object appears differently when illuminated with different light sources, giving the impression that the color of an object is also tied to the light source used. This property of the illuminating light source can be quantized as CRI [Color Rendering Index]. The CRI defines how accurately a sample light source reproduces an illuminated object’s color in comparison to a reference light source of comparable color temperature. Figure 1 shows an example where the same object appears differently when illuminated with light sources of different CRI. Cypress Semiconductor Corp.

Wideband couplers have many practical applications at microwave frequencies. If realized in an inhomogeneous medium such as microstrip, these couplers yield poor directivity, which results in severe performance degradation. One of the major reasons for poor directivity is the mismatch in the odd and even mode phase velocities, along the coupled lines. Several methods have been suggested for compensating for the phase velocity mismatch, but these are limited to narrow bandwidths. The undergraduate design project described in this success story investigates the design and simulation of a unique wideband coupler that improves directivity by increasing the number of stages of the coupled line coupler, thus resulting in a multistage coupler, which improves bandwidth performance and, with optimally positioned capacitances, delivers improved directivity and phase compensation.

Avago uses enhancement-mode pHEMT (E-pHEMT) process for its PA design while most competitors have developed GaAs HBT technology. This paper shows why E-pHEMT technology can provide superior electrical and reliability performance for power amplifier design in wireless communications. Avago Technologies

A High Isolation Buffer
The design and implementation of a high isolation buffer amplifier is presented. This IC uses a two gain stage topology processed in the Avago Technologies Enhancement Mode pHEMT GaAs technology and is packaged in the 8-lead 2mm x 2mm LPCC. It operates preferably from a 5 Volt supply and consumes approximately 35 mA quiescent current. By varying an external bias resistor, the buffer amplifier can deliver maximum output power up to 20 dBm at 2 GHz. It has better than 40 dB of input-output port isolation and operates from 0.5 GHz to 6 GHz. Avago Technologies

Development EpHEMT
E-pHEMT (enhancement-mode high-electron mobility transistor) is a semiconductor process optimized for wireless applications that operate from a single positive voltage source. Ordinary depletion-mode pHEMTs conduct at zero gate bias, or when the drain current, Id, reaches a saturated level (Idss) at a gatesource voltage (Vgs) of 0 VDC. An E-pHEMT shows no conduction at zero gate bias, so that Id = 0 at Vgs = 0V. Thus, it can operate without the negative voltage (required for switch on) required for depletionmode devices.

Microdul gains deeper
Microdul produces proximity sensor chips that can be used with remote sensing plates. Changes in plate capacitance are detected by a digital auto-calibrating algorithm. An approaching human finger typically causes a switching operation. This principle is demonstrated in Figure 2. The capacitive switch can be used for many non-contact applications. The main challenge is to develop a sensor which can reliably distinguish between intentional switching operation and environmental interference. CST - Computer Simulation Technology

Comparison of 2.4-GHz
With the penetration of Wireless technology into the human interface device (HID) market, more and more sophisticated HID products are now coming out in the market with integrated wireless technology (wireless keyboards, wireless mice, etc). Often, developers are limited in their options: follow a popular wireless standard like Bluetooth or develop a proprietary protocol optimized for their application. While wireless standards provide the benefit of interoperability, they also introduce complexity and overhead that an application may not require, resulting in a higher system cost. On the other hand, proprietary protocol gives developers flexibility to customize applications at the expense of requiring developers to take on the development process. Cypress Semiconductor Corp.

Acme Cellular_062509.pdf
As a result of inaccurate forecasting, Acme Cellular’s worldwide market share of cellular phone sales was declining. Our product portfolio included five different models of cellular phones (AC-1 through AC-5). Each model is available in 6 different configurations for various languages and service providers. We also have three suppliers for Flash memory devices: Samsung, Toshiba, and Micron. Inventory control, for both unprogrammed (blank) and pre-programmed Flash memories, is critical, as more than 90 different part numbers must be generated and managed. Compounding these forecasting problems were shipping delays due to last- minute code changes. Data I/O Corporation

In the context of electronic product manufacturing, mission-critical applications are those that are vital to the functioning of an overall system. If the application fails, there are typically undesirable results which might jeopardize human lives or may cause significant damage or loss. Examples of these applications are the brake or air bag system in your car, the chip inside a heart monitoring system, or the chip inside the circuitry that controls the navigation system of an airplane. Even though these are dramatic examples of mission-critical applications, our daily lives are full of similar applications with very low to no tolerance for failure. Data I/O Corporation
