Hey functional verification is nothing but testing the functionality by checking wherether all permutations and combinations are covered or not. I am uploading a presentation and one doc showing functional coverage.

hi,

Functional Coverage provides an indication of the thoroughness of the implementation of the verification plan and can help answer questions such as how much of the design specification has been exercised? and what actually happened during a test? As chip designs grow larger and more complex with thousands of possible states and transitions, a comprehensive verification environment must be created that minimizes wasted effort. Functional coverage is used as a guide to direct the verification resources by identifying the tested and untested parts of the
design. When properly used, functional coverage can serve as a formal specification of a test plan. In turn, the process of writing functional coverage can bring holes in a test plan to the attention of verification personnel.
Functional coverage, because it is a measure of what is determined to be of interest and relevant,must be manually specified by members of the design and verification team. It cannot be extracted automatically from the design source code.
