Abstract

As technology advanced, the demand for data bandwidth has been increasing. To meet this demand, the data rate of the channel has been increased, which causes a lot of signal integrity problems. Optimization of the channel is important to solve these problems. Channels are usually optimized with the empirical knowledge of signal integrity designers. However, it is not accurate and requires numerous iterations. On the other hand, a Bayesian optimization method can quickly find optimized parameter values without relying on empirical knowledge. Therefore, this paper proposes a method for optimizing high-speed channel using Bayesian optimization. The proposed method optimizes the frequency response result such as insertion loss, and find the optimal physical dimension parameters. Finally, the optimized results of the proposed method were verified by comparing all the simulation results in the range of the channel.

高速通道信号完整性分析的贝叶斯优化

随着技术的进步，对数据带宽的需求越来越大。为了满足这一需求，提高了信道的数据速率，这就造成了很多信号完整性问题。渠道的优化是解决这些问题的重要途径。通道通常通过信号完整性设计人员的经验知识进行优化。然而，它并不准确，并且需要多次迭代。另一方面，贝叶斯优化方法可以在不依赖经验知识的情况下快速找到优化的参数值。因此，本文提出了一种基于贝叶斯优化的高速信道优化方法。该方法对插入损耗等频率响应结果进行了优化，并找到了最优的物理尺寸参数。最后，在信道范围内对所有仿真结果进行比较，验证了所提方法的优化结果。
