Study on High-Efficiency Debug Methods of High Speed SerDes Based on Serial Port

With the rapid increase of the transmission rate of high-speed serializer/Deserializer(SerDes),the complexity of function and performance parameters of high-speed SerDes increases.Therefore,efficient debugging methods for high-speed SerDes have become an important domestic and foreign study.Based on the analysis of the existing debugging methods,this paper proposes a debugging method of high-speed SerDes based on serial port,and the corresponding serial port protocol is designed to realize the dynamic debugging of SerDes parameters.Compared with the traditional SerDes testing methods,the solution in this paper not only satisfies the debugging needs of all SerDes parameters,but also greatly reduces the number and time of test vectors.This method is convenient for tester and user to debug.At the same time,it is more versatile.
