In this book, renowned engineer, author, andseminar leader Douglas Brooks teaches PCB designers how tosuccessfully design boards for any high-speed application. Brooksbegins with an easy-to-understand electronics primer for every PCBdesigner, then offers practical, real-world solutions for everyimportant signal-integrity problem.Based on his legendary seminars,this book offers even more design rules, specific recommendations,examples, illustrations, and diagrams.
The new material is aimed at those electrical/electronic or computer engineers designing circuits and printed circuit boards in the telecom, embedded systems and computer industries needing to understand fundamental signal integrity concepts and how to solve common signal integrity problems. It retains the 1st edition's advanced material that serial channel designers, custom chip and ASIC designers and their test engineers found so useful.
In 2011 I published the introductory text, Understanding Signal Integrity, specifically for those students, managers and the many experienced engineers unfamiliar with signal integrity. Besides the electrical engineering of signal integrity, the book introduces the unique language and terminology used by practitioners and by circuit board designers. It contains suggested plans of attack for diagnosing and solving common signal integrity problems. Several chapters have solved exercise problems that help cement ideas and can be used as templates to solve similar problems in actual hardware.
In 2004 I wrote High-Speed Circuit Board Signal Integrity to help high-performance circuit board designers and ASIC designers understand the physics and signal integrity issues surrounding high-speed signaling. This is an advanced text popular with ASIC designers and those board design engineers working with high-speed signaling.
This eBook covers some key applications where oscilloscopes are best suited to make the important measurements to evaluate your designs. The articles cover practical printed circuit board design and manufacture to reduce noise; triggering on radar RF pulses with an oscilloscope; demodulating radar RF pulses with an oscilloscope; low noise, sub-milliOhm measurements in very small circuits; and power integrity measurements.
This is the first co-contributed eBook with articles from both Microwave Journal and Signal Integrity Journal as the versatile oscilloscope is used for measurements for wireless and high-speed circuits. This eBook covers how phase-locked loops enable many applications and simplify calibration with phase resynchronization & phase adjustment, an easy and simple way to measure the bandwidth of a scope-probe system, tackling power distribution network issues, accurate & fast power integrity measurements, avoiding artifacts when measuring switch-mode power supplies, PAM4 measurements & challenges, and ground bounce & how to accurately measure & avoid it.
One of the fundamental problems with high-speed design in general and PCB/interconnect designs in particular, is that problems tend to be intermittent and hard to troubleshoot. So, as a PCB designer, how do you avoid the headaches of mysterious SI or PI issues on board? How do you select the best interconnects for the job to make them as transparent as possible to your design?
When designing a board with elaborate ICs such as FPGAs, it is important to calculate the FPGA demand on the PCB and vice-versa. Below you will find information on signal integrity, static and dynamic power, and SSO:
The book describes all of the principles involved in high-speed design such as transmission line management, signal integrity, power subsystem design, PCB materials and EMI control. Each technical term is defined in terms of its physics and how it applies to high-speed design. In addition, PCB material and fabricator selection, cost issues and design trade-off decisions are discussed in detail to provide the complete picture of all the factors involved in designing and implementing high-speed systems.
The easy-to-use power distribution network (PDN) design tool is a graphical tool used with all Intel® FPGAs to optimize the board-level PDN. The purpose of the board-level PDN is to distribute power and return currents from the voltage regulating module (VRM) to the FPGA power supplies, and support optimal transceiver signal integrity and FPGA performance.
For each power supply, you must choose a network of bulk and ceramic decoupling capacitors. While you can use SPICE simulation to simulate the circuit, the PDN design tool provides a fast, accurate, and interactive way to determine the right number of decoupling capacitors for optimal cost and performance trade-offs. By determining the optimal set of decoupling capacitors for a given design, you can save board space and ease the board layout process.
The PDN printed circuit board design methodology is described in detail in AN 574: Printed Circuit Board (PCB) Power Delivery Network (PDN) Design Methodology (PDF). It also describes the role of the FEFFECTIVE in designing an efficient system power delivery solution.
Goals: The execution of modern digital electronic systems designs presents challenges that demand new ways of thinking about such problems. Building upon the fundamental concepts of electronic circuits and those developed in EE 271, the main objective of EE 371 is to provide students with a theoretical background to and practical experience with the tools, techniques, and methods for solving challenges related to modeling complex systems using the Verilog hardware description language (HDL), signal integrity, managing power consumption in digital systems, and ensuring robust intra and inter system communication.
We will work with the Altera DE1-SOC development board that utilizes the Cyclone V FPGA combined with a variety of peripheral devices, including the embedded NIOS II processor, as our target hardware platform. The hardware side of the applications will be specified then designed, modeled, and tested using the Verilog HDL and the libraries and tools provided under the Quartus II development environment. We will synthesize then download the tested modules onto the DE1-SOC board where they will be integrated into a complete working system. The software side of the applications will be written in C, cross-compiled under the NIOS II IDE then downloaded and executed on the embedded NIOS II processor.
Gerber, ODB++, and IPC-2581 all have enthusiastic advocates, and all three are being used to produce circuit boards. Which brings us to these questions: Is there really a problem with having three perfectly good design data formats? Does the industry have to unite around one? Or do we all just like a good horse race? These are just a few of the questions that our contributors discuss in the October issue of Design007 Magazine.
There are a variety of ways to terminate and connect a flexible circuit to a rigid board. But the stress on the flex circuit must be considered to avoid broken connections, and many flex connectors come with long lead times. This month, we look at some of the best techniques for terminating flexible circuits. One tip: Work out your connection strategy well in advance of beginning the design process.
This month, the feature column by Joe Fjelstad explains why until recently, thermal issues had been the Rodney Dangerfield of PCB issues. We also bring you columns by John Talbot and Dominique Numakura and an article from Tony Plemel on the importance of documenting your flex circuit designs.
This month, we start with a feature column by Tara Dunn, who illustrates how flex fab notes differ from their rigid PCB brethren and how the 3D structure of flex presents even more data challenges. Dominique Numakura brings us a follow-up to his column series on monocoque printed circuits. We also have a great article by Olga Scheglov, CID+, who lays out a series of design rules for new flex designers.
Flex007 ColumnsDesigning and manufacturing rigid PCBs can be challenging. But flexible circuit technologists face a plethora of issues that their rigid counterparts never dreamed of. One advantage for the flexible circuit designer: the three-dimensional nature of flex allows for innovations that are impossible for rigid boards. Is flex really the new frontier?
The design economics related to creating flexible and rigid-flex circuits are similar to that of their rigid board counterparts, but the 3D nature of flex can lead to a variety of potential hurdles on the way to cost-aware design. This month, our expert contributors examine the economics of flexible circuit design from a variety of industry viewpoints.
We start with interviews with Michael Steffen and Kalen Brown, who discuss their work as designers and why they decided to take the CID exam. Next, Todd Westerhoff of Mentor explains why the designers of today need to understand many concepts once left to the signal integrity engineers. Then, Bryan LaPointe of Cadence Design Systems discusses the satisfaction he feels working as a product engineer, as well as the diversity of the entire EDA segment. Matt Stevenson of Sunstone Circuits breaks down some of the reasons why this may be the most exciting time to be in this field.
