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.
