摘要
针对传统的最坏眼图技术通常会导致过量设计的问题,从统计域的角度提出了一种既定数据率下的通道误码率眼图的求解方法。文中采用双边沿响应法,基于DDR4十线模型将通道的码间干扰和串扰的影响同时考虑在内。通过给发送的码元赋以概率,再对卷积运算的结果进行处理,绘出最终的误码率眼图,不只局限于最坏眼图,因此更具有实用价值。
As the traditional worst eye diagram often leads to excessive design,a method for calculating the channel bit error rate（ BER） eye diagram under a given data rate is proposed from the perspective of statistical domain. The DER（ double edge response） method based on DDR4 ten lines model takes into account both the channel inter-symbol interference and the cross-talk effects. The final BER eye diagram is obtained by adding probability to bits and dealing with the result of the convolution operation. This method is not limited to the worst eye diagram,and thus is more practical.
