摘　　要：随着产品的速率及复杂性越来越高,针对仿真而言,除了要求仿真本身具有非常高的精度外,还对仿真的效率提出了很高的要求。具体到不同的信号模块,如DDR系统或者高速串行信号上,基于速率越来越高,越来越希望仿真给能出“最优解”的配置,例如DDR5颗粒的ODT的最优配置,高速信号芯片的加重均衡的最优配置等参数。那么如何在成百上千种组合的参数中选择相对最优的参数呢?传统的软件只能通过大量的扫描来进行筛选,在仿真时间和工程师的精力两方面都有比较大的耗费。使用Optimality软件,通过分享一些具体的仿真案例,展现软件的智能性,帮助使用者更快速挑选出最优的参数,使DDR及高速串行的仿真工作变得更加轻松,充分体现出Optimality软件的高效性。With the increasing speed and complexity of products,for simulation,it not only requirs the simulation itself to have a very high accuracy,but also puts forward high requirements for the efficiency of simulation.Specific to different signal modules,such as DDR systems or high-speed signals,because of the increasing speed,more and more people hope simulation can tell us the"optimal solution",such as the optimal configuration of DDR5 particles ODT,the optimal equalization and de-emphasis configuration of chip.How do you get the relatively optimal parameter among hundreds or thousands of combinations of parameters?Traditional software can only be screened through a large number of scans,which has a relatively large cost in both simulation time and engineer's energy.In this paper,Optimality software is used.By sharing some specific simulation cases,we can see the intelligence of the software,which can help us select the optimal parameters more quickly,make the simulation work of DDR and high-speed module easier,and fully reflect the efficiency of this software.
