| 摘要: |
| 针对高密度存储服务器中高速链路结构复杂、信号速率高、链路长度长等特点，在高速链路PCI-E3.0和SAS3.0设计过程中引入全面的信号完整性仿真。通过对高速印刷电路板设计中拓扑结构、材料类型、印刷电路板结构等关键项目进行仿真设计，获得成本最低、性能达标的最优方案；通过全链路有源仿真，预估系统性能，降低系统投产风险；通过系统实际信号测试，验证系统性能完全满足相应规范要求，仿真结果有效可靠。 |

| Abstract: |
| Comprehensive signal integrity simulation was introduced in the design of PCI-E3.0 and SAS3.0 channels of high density storage server, which are characterized by complicated structures, high signal speed and long and dense traces. The optimized cost-effective design was obtained by simulating the key items of high-speed PCB design such as topology, material and high-speed via structure. The system performances were then evaluated by full channel active simulation to ensure the stability of the system and reduce the manufacture risks. The signal quality of storage server system totally meets the requirement of PCI-E3.0 and SAS3.0 specifications, verifying the effectiveness and reliability of signal integrity simulation. |
