Efficient Circuit-Level Implementation of Knuth-Based Balanced and Nearly-Balanced Codes
Pamela A. Riggs, Barry K. Gilbert, Erik S. Daniel
Coding schemes are often used in high-speed processor-processor or processor-memory busses in digital systems. In particular, we have introduced (in a 2012 DesignCon paper) a zero…
Inverting the SerDes Link Design Flow Process
Michael J. Degerstrom, Chad M. Smutzer, Patrick J. Zabinski +1
The traditional SerDes link simulation process begins with the extraction of printed circuit board (PCB) physical stripline and via models, followed by channel modeling and link si…
56 Gbps PCB Design Strategies for Clean, Low-Skew Channels
Michael J. Degerstrom, Chad M. Smutzer, Barry K. Gilbert +1
Although next generation (>28 Gbps) SerDes standards have been contemplated for several years, it has not been clear whether PCB structures supporting 56 Gbps NRZ will be feasible…
A Zero Sum Signaling Method for High Speed, Dense Parallel Bus Communications
Chad M. Smutzer, Robert W. Techentin, Michael J. Degerstrom +2
Complex digital systems such as high performance computers (HPCs) make extensive use of high-speed electrical interconnects, in routing signals among processing elements, or betwee…
PWB Manufacturing Variability Effects on High Speed SerDes Links: Statistical Insights from Thousands of 4-Port SParameter Measurements
Bart O. McCoy, Robert W. Techentin, Benjamin R. Buhrow +4
Variability analysis is important in successfully deploying multi-gigabit backplane printed wiring boards (PWBs) with growing numbers of high-speed SerDes links. We discuss the nee…
High Speed Parallel Signal Crosstalk Cancellation Concept
Chad M. Smutzer, Michael J. Degerstrom, Barry K. Gilbert +1
High performance computing (HPC) systems make extensive use of high speed electrical interconnects, in routing signals among processing elements, or between processing elements and…
Comparison of Optical and Electrical Links for Highly-Interconnected Systems
James Kruchowski, Vladimir Sokolov, Nathan E. Harff +5
As data rates for multi-gigabit serial interfaces within multi-node compute systems approach and exceed 10 Gigabits per second (Gbps), board-to-board and chip-to-chip optical signa…
Applications of Optimization Routines in Signal Integrity Analysis
Pat J. Zabinski, Ben R. Buhrow, Barry K. Gilbert +1
Signal integrity analysis often involves the development of design guidelines through manual manipulation of circuit parameters and judicious interpretation of results. Such an app…
Power Supply Compensation for Capacitive Loads
Jonathan L. Fasig, Barry K. Gilbert, Erik S. Daniel
As ASIC supply voltages approach one volt, the source-impedance goals for power distribution networks are driven ever lower as well. One approach to achieving these goals is to add…
Time Domain Verification of Differential Transmission Line Modeling Methods
Jonathan D. Coker, Erik S. Daniel, Barry K. Gilbert
The advantages and limitations of time-domain pseudo-random binary sequence (PRBS) excitation methods for system identification of individual modes within a multi-conductor transmi…
