System and method to optimize equalization coefficients in a high-speed serial interface

A method of training a high-speed serial data interface, the method comprising:

• setting, by a control module of a receiver of the high-speed serial data interface, an output impedance of a transmitter coupled to the receiver via the high-speed serial data interface, the output impedance being selectable from a plurality of output impedance values;
• determining, by the control module, that a performance level of the receiver is below a first performance level threshold;
• setting, by the control module, a first setting of a first compensation module of the receiver with a first whitelist value in response to determining that the performance level of the receiver is below the performance level threshold, the first compensation module to control a first characteristic of the receiver, the first whitelist value from a plurality of first values of the first setting, and the first whitelist value stored in a memory of the receiver;
• reevaluating the performance level of the receiver using the first whitelist value;
• and
• applying the first whitelist value to the first compensation module when the reevaluated performance level is above the performance level threshold.
