Method and apparatus for clocked data eye measurement at synchronous interfaces is provided. A receiver may generate first vector information corresponding to data received on at least one communication channel at the receiver. The receiver may generate second information regarding when the data was latched by a clock signal, the clock signal being received on a separate communication channel at the receiver. The first vector information may be combined with the second information to generate combined information, the combined information indicating a quality of latching the data.
