Abstract:

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.
