摘要：

信号传输速率是衡量高性能计算机系统的一项重要指标，随着现代高性能计算系统中的信号传输速率达到并超过10Gbps，快速提高的信号速率使得高速通道的设计面临严峻挑战。基于信号完整性仿真分析，对一款14Gbps高速通道进行优化设计。通过手动3D建模与真实模型提取的混合建模技术提高仿真速度，采用全通道协同仿真预测高速通道的整体性能和瓶颈，并重点对过孔、介质材料、线宽和线间距等进行仿真实验与优化，成功实现了14Gbps高速信号的稳定传输。

Abstract:

The signal transmission rate is an important index of high performance computing. As signal transmission rate of modern high performance computing systems is continuously increasing, which reached to, even over 10Gbps, the design of highspeed channel faces severe challenge with the rapidly increased signal rate. Based on the guidance of the simulation analysis on signal integrity, a 14Gbps high-speed channel is optimized and designed. Through combining the manual 3D model with the extracted PCB model, the simulation analysis is speeded up. The full channel co-simulation is used to forecast the overall performance and the bottleneck of the high-speed channel, and we focus on optimizing the hole, dielectric materials, line width and line space etc. Finally, we successfully carry out the stable transmission of 14Gbps high-speed signals.
