Abstract

A method for determining a signal quality includes: receiving a signal from a circuit device; generating multiple eye diagrams according to the signal; determining whether each eye diagram is normal according to a basic index to generate a first determination result, wherein the basic index comprises an eye height and an eye width; in response to the first determination result indicating that each diagram is normal, determining whether each eye diagram is normal according to an advanced index to generate a second determination result, wherein the advanced index comprises at least one of a combination of an area and a contour length, a combination of a density and a gradient, and a combination of multiple slopes; and in response to the second determination result indicating that each eye diagram is normal, determining the signal quality of the signal according to each of the multiple eye diagrams.

Dependent claims

A method for determining a signal quality, comprising:

receiving a signal from a circuit device;
generating multiple eye diagrams according to the signal;
determining whether each of the multiple eye diagrams is normal according to a basic index to generate a first determination result, wherein the basic index is derived from each of the multiple eye diagrams, and comprises an eye height and an eye width of each of the multiple eye diagrams;
in response to the first determination result indicating that each of the multiple eye diagrams is normal, determining whether each of the multiple eye diagrams is normal according to an advanced index to generate a second determination result, wherein the advanced index is derived from each of the multiple eye diagrams, and comprises at least one of a combination of an area and a contour length of each of the multiple eye diagrams, a combination of a density and a gradient of each of the multiple eye diagrams, and a combination of multiple slopes of each of the multiple eye diagrams;
and
in response to the second determination result indicating that each of the multiple eye diagrams is normal, determining the signal quality of the signal according to each of the multiple eye diagrams.
