How to generate the detailed coverage report of functional coverage? I am using following command to simulate my code :

 vlog -64 -work work -vopt +notimingchecks  +cover +fcover  -f pcie_jammer.f 

 vsim -novopt -c <CODE SPECIFIC ARGS> -t ps work.tb_top work.glbl -vopt -do "set WildcardFilter None;**coverage save -onexit -directive -cvg -codeAll pcie_cov_${1}_gen${speed}_X${width}** ; add log -r /*;coverage report -file pcie_cov_${1}_gen${speed}_X${width}.txt -byfile -detail -noannotate -option -directive -cvg -details -verbose;**coverage report -directive -cvg -details -verbose**;run -all;exit" > transcript_${tname}_gen${speed}_X${width}.txt  

 vcover report -html pcie_cov_${1}_gen${speed}_X${width} -verbose

I am not able to see the details of the covergroup in the report.

After some research I am able to solve the above question. Please find the solution below:

To generate a detailed function coverage report:

1.First compile and simulate your code using below mentioned script :

vlog -work work -O0 +fcover +acc -f pcie_jammer.f 
vsim -cvgperinstance -c <ARGUMENTS> work.tb_top work.glbl -do " coverage save -onexit <Name_of_File>.ucdb; run -all;exit"

Save the coverage report of the simulation in a UCDB file (Refer Questa User Manual for details about UCDB file).

2.In order to get a html or text report, reload the formed ucdb file and use coverage report to form the report as follows:

vsim -cvgperinstance -viewcov merged.ucdb -do "coverage report -file final_report.txt -byfile -detail -noannotate -option -cvg"

One can also use Questa GUI to form the report.

This approach is quite useful in order to merge the functional coverage reports of multiple testcases.

After creating .ucdb file go to console (cmd) and type the following commands:

vcover report -details -html result.ucdb

(this is for html report with details.)

vcover report -details result.ucdb

(this is for questasim.)
