Abstract: A parameter adjustment method and apparatus are provided. The parameter adjustment method for a communication device with a SerDes link includes: acquiring, by the communication device, a current ambient temperature of the communication device; and if according to a preset correspondence between a temperature range and a parameter, the current ambient temperature is determined to be not corresponding to a SerDes parameter of the communication device, adjusting the SerDes parameter of the communication device according to the correspondence. The SerDes parameter of the communication device is adjusted in real time, thereby improving reliability of a SerDes link of the communication device, and reducing a bit error rate of the SerDes link.

Abstract: A method for configuring a high-speed serial bus parameter, including sending an application signal from a transmit end of a high-speed serial bus to a receive end of the high-speed serial bus, searching a parameter configuration table for a high-speed serial bus parameter that matches all of a frequency of the application signal, a loss of the application signal on the high-speed serial bus, and a material type of a wiring board of the high-speed serial bus, and configuring the high-speed serial bus according to the high-speed serial bus parameter. According to the method, a problem involving configuration of a high-speed serial bus parameter when a transmitted signal is compensated may be solved.
