Testing the eye opening of an eye-pattern signal

There are generally two tests that you want to perform on an eye-pattern
signal: an eye boundary test and an eye opening test. Since the eye
boundary can be easily tested by using the normal mask template testing, this
section mainly focuses on how to create the mask for testing the eye opening.

A fail region in the shape of a hexagon is usually used to test the eye opening.
An example of the shape of the mask is shown below.
