Need help for functional coverage

SystemVerilog
1

Hello sir,
I have done coverage of my vip. I am using questasim 6.6f.

For simulation i am using command ‘vsim -solvefaildebug -c top -do “coverage save -on exit cover.ucdb;run -all;quit”-coverage-voptargs=“+cover=bcfst”|tee log’

And to see coverage report i am using command ‘vcover report -html -htmldir cov cover.ucdb’

But it shows me coverage in percentage. It not shows me detailed coverage means which bins are covered and which bins are not covered. So is there any option by that i can find detailed coverage. I have tried all the switches mentioned in the Questasim user manual.

Thanks in advance…

Regards,
VsP

Vsp,

If you are talking about functional coverpoint bins, you don’t get that detailed information by default. I know that they added some switches in 10.0 to make this easier, but I don’t remember what you need to do in 6.6. Questa is now at version 10.1.

You would get better Questa tool help by contacting supportnet.mentor.com.

hello sir,
i have used the command “vcover report -html -htmldir cov cover.ucdb”.
but I am getting the error since my cover.ucdb file is also generated before this and present in the same directory.
i am using questasim tool.
Error: (vcover-7) Failed to open UCDB file “cover.ucdb” in read mode.
