$load_coverage_db(filename) usage

Hello Everyone,
In LRM, it was mentioned that “$load_coverage_db(filename) loads from the given file name the cumulative coverage information for all coverage group types.”

Does anybody know, How to use “$load_coverage_db(filename)” in real time?
Does this task has return type? How to analysis the coverage with this task ?

Thanks,
SG.

Using $load_coverage_db is not necessary because most tools provide much better coverage analysis than what is available in the LRM.

All this task does is load up coverage data from a previous simulation and any further simulation will add to it. Normally all coverage counters are set to 0 at the start of a simulation. Now they will be set to whatever counters had in the database.
