hi,

I think that there should be code coverage tool option in modelsim if that feature available with your licence. with out that you can not do that i think so if there is any appropriate answer then please let me know

questasim batch mode

If I'm not mistaking , Tools -> Coverage -> Reports. At path input box, u will put the name of the report file.

OR
in command line :
coverage report -file file.txt

I hope it's useful for you....

Have a nice day to all,

Dexter

questasim coverage merge

You can do:
vsim -c -do "coverage save -onexit <TESTSET_CODE_COVER>.ucdb;run -all;exit" -coverage -voptargs="+cover=bcfst" <otherOptions> <TOP>

Here we tell vsim to
1) enable code coverage (-coverage),
2) the types of coverage to collect (via -voptargs=+cover= bcefst") if not using the three-step flow process,
3) and to produce a coverage database file on the exit of simulation (do "coverage save -onexit coverage.ucdb)

Further if you have multiple coverage databases, you can merge them into a single database by using:
vcover merge <ucdbFile1>.ucdb <ucdbFile2>.ucdb ... <ucdbFileN>.ucdb <ucdbFileResult>.ucdb

The finally you can generate a HTML report:
vcover report -html -htmldir <dirToOutput> -verbose -threshL 50 -threshH 90 <ucdbFile>.ucdb
