Location: Steigenberger Hotel
Bad Homburg, Kaiser-Friedrich-Promenade 69-75, 61348 Bad Homburg, Germany
This comprehensive 3 day course from High Speed Design´s "Ratchet Man" covers all key aspects of the high speed design process. If you can take only one course on this subject, this is the one for you.
Practical and Comprehensive
This highly practical course is designed to take the student through the entire process involved in designing and fabricating high speed PCBs. It begins with the fundamentals of electromagnetic fields and the behavior of transmission lines that are the basis for all high-speed signaling. From there, it examines all of the aspects of high-speed design leading to the development of a robust set of PCB design rules that accounts for power subsystem design, routing rules and design of PCB stack-ups as well as the fabrication rules needed to balance performance against cost and manufacturability.
The materials and examples used in this course are drawn from actual designs of high speed systems in current manufacture. These examples range from video games to terabit routers and cover the complete range of designs. The design process presented is based on many years of completing designs that are "right the first time". Students are shown many ways to improve their design process so that designs meet this objective. Reliable methods for controlling and containing EMI will also be thoroughly covered.
This course places special emphasis on very high speed differential signaling protocols such as XAUI, Hypertransport, PCI Express, Infiniband, SATA, SSCSI and others that are the backbone of modern computing. Actual circuits are built and tested and then modeled to correlate modeling techniques. The topic of how to design power delivery systems capable of supporting these protocols is also addressed.
Lee Ritchey is considered to be one of the industry´s premier authorities on high speed PCB and system design. He has participated in the design of more than 1000 high speed PCBs ranging from PC mother boards and elevator controllers to the backplanes used in terabit routers. He is currently involved in the design of several super computer class products as well as video games and servers of all kinds.
The course draws substantially from this real-time experience with state of the art components, fabricators and materials. It also draws heavily on the design of backplanes and daughter boards containing thousands of 2.4, 4.8 and 9.6 GB/S and 10 - 32 GB/S signal paths.

Why Take This Course
Electronic designs of all kinds are operating with increasingly faster clock rates and rise times. At the same time, the pressure to complete designs in fewer design cycles is putting pressure on design teams to deliver designs to manufacturing that are "right the first time". In order to account for the normal variations in component edge rates, propagation delay variations, amplifier gains, logic levels and variations in the PCB fabrication process, it is necessary to invoke the use of design tools and methods that allow "preroute" analysis to insure the final product is designed correctly. With the speeds of signals and components rising into the gigahertz range, relying on the traditional bread boarding or hardware prototyping process often results in a product never making it to market.
This increase in component speed has made it necessary for all design engineers to master the design techniques that were once only the province of super computer engineers. This course relies heavily on the proven methods developed for supercomputers and terabit routers. It also draws on experience with disc drives and high performance video games.
This course addresses the most common high speed problems, including:
Failures from crosstalk and reflections
Problems related to time delays in PCB traces
Failures stemming from poor power system design
Failures related to poor IC package design
LEE RITCHEY, BSEE, founder and president of Speeding Edge, is considered to be one of the industry´s premier authorities on high-speed PCB and system design. Prior to founding Speeding Edge, Ritchey served as program manager at 3Com Corporation where he managed a corporate-wide signal integrity group responsible for the design rules used to develop high performance networking equipment such as routers and switches. Before that, he managed a development team at Maxtor Corporation, a developer of high performance disc drives. He was co-founder of Shared Resources, a design services company specializing in the design of high-end supercomputers, work stations and imaging products. He began his career as a microwave engineer on the Apollo program.
He is currently providing signal integrity engineering services to several network equipment manufacturers as well as a supercomputer project with 110,000 processors and data links running at 5.2 GB/S. He has taught high speed design courses since 1992.
In 2004, Ritchey was a regular columnist for EE Times and he has written many articles on high speed design for trade publications such as EDN, Circuitree and PC Design. He is the author of the book, "Right the First Time, A Practical Handbook on PCB and System Design, Volume 1" published by Speeding Edge in 2003. He recently completed Volume 2 of Right The First Time, A Practical Handbook on High Speed PCB and System Design.
The course fee includes a copy of the course slides.
