Equalization coefficient search algorithm

A non-transitory computer-readable medium that, when executed by a processing unit, causes the processing unit to analyzing equalization coefficients for a high-speed data bus, by performing the steps of:

• selecting a starting point on a map of equalization coefficients, wherein each point on the map comprises a different set of equalization coefficients;
• measuring an eye height of a signal transmitted using the set of equalization coefficients associated with the starting point and an eye height associated with each adjacent point on the map relative to the starting point, wherein the eye height associated with an adjacent point is based on a signal transmitted using the set of equalization coefficients associated with the adjacent point;
• and
• walking on the map in a first direction from the starting point to the adjacent point associated with the greatest eye height, wherein the eye height associated with the adjacent point is greater than or equal to the eye height associated with the starting point.

A computing device, including:

• a processor;
• and
• a memory coupled to the processor and including a software application that, when executed by the processor, causes the processor to:
• select a starting point on a map of equalization coefficients, wherein each point on the map comprises a different set of equalization coefficients;
• measure an eye height of a signal transmitted using the set of equalization coefficients associated with the starting point and an eye height associated with each adjacent point on the map relative to the starting point, wherein the eye height associated with an adjacent point is based on a signal transmitted using the set of equalization coefficients associated with the adjacent point;
• and
• walk on the map in a first direction from the starting point to the adjacent point associated with the greatest eye height, wherein the eye height associated with the adjacent point is greater than or equal to the eye height associated with the starting point.
