In order to calculate the coverage on a coverpoint, we first need to determine the number of possible values, which is also called domain. Coverage is the number of sampled values divided by the number of bins. For example, the domain of a 3-bit variable is 0:7. Normally, 8 bins will be automatically allocated.
