MULTIPASS APPROACH FOR PERFORMING CHANNEL EQUALIZATION TRAINING
First Claim
1. A computer-implemented method for analyzing equalization coefficients for a high-speed data bus, the method comprising:
- performing a first pass test over a plurality of sets of equalization coefficients to filter the plurality of sets of equalization coefficients to produce one or more filtered sets of equalization coefficients, wherein each filtered set of equalization coefficients meets a first predetermined threshold;
performing a second pass test over the one or more filtered sets of equalization coefficients to determine a final set of equalization coefficients that meets a second predetermined threshold, wherein the second pass test produces more accurate results than the first pass test.

Abstract
A method comprises performing a first pass test over a plurality of sets of equalization coefficients to filter the plurality of sets of equalization coefficients to produce one or more filtered sets of equalization coefficients. Each filtered set of equalization coefficients meets a first predetermined threshold. The method also comprises performing a second pass test over the one or more filtered sets of equalization coefficients to determine a final set of equalization coefficients that meets a second predetermined threshold. The second pass test produces more accurate results than the first pass test.
