This function loads and merges coverage data for the specified coverage into the simulator. name is an arbitrary string used by the tool, in an implementation-specific way, to locate the appropriate coverage database, i.e., tools are allowed to store coverage files any place they want with any extension they want as long as the user can retrieve the information by asking for a specific saved name from that coverage database. If name does not exist or does not correspond to a coverage database from the same design, an error shall occur. If an error occurs during loading, the coverage numbers generated by this simulation might not be meaningful. </p>
