Please Explain the false coverage and yeah if any other terms are also use in industry like this than also elaborate it. What is the approach to cover the hole coverage ?
This usually means a bug in your coverage model, or incomplete coverage. This usually means you are reporting a higher coverage number than actually exist.
A coverage hole is an area of coverage. We’re trying to collect but have not hit yet. You can also have unreachable coverage for example, you’re trying to collect code coverage for a line of code that will never execute.
The approaches for dealing with this are quite involved, depending on the design requirements and test bench methodologies used. You can search for articles on this as there are plenty of them.
