I'm running multiple UVM tests for a certain DUT, I want to collect coverage statistics for all these tests By running the following command I get a detailed report on coverage after running simulation


coverage report -file report.txt -byfile -detail -all -dump -fecanalysis -metricanalysis -option -assert -directive -cvg -codeAll

the problem is that this report only includes statistics from the last test that was run , the file is overwritten after every test

I want to merge coverage statistics, I searched and found that I should used UCDB files but can't find any details on how to do so and produce a text file report.
Any help would be appreciated.
 

I just found this forum few days ago while I was tackling with a very similar problem.
In my case I have a for loop in which I run multiple tests for a single dut and I want to see how each one of them did.
I use this as an option for vsim command
Code: 
-do "coverage save -onexit $TEST.ucdb; run -all"
to create .ucdb file and then after the test I use

Code: 
vsim -c -cvgperinstance -viewcov $TEST.ucdb -do "coverage report -file ${TEST}.txt -byfile -detail -noannotate -option -cvg; quit -f"

to translate that into a txt file which I then parse with greps and awks into my own custom summary report.
Did it this way because I didn't know any better.

Read about the command "vcover merge".

I actually did use it but can't get the ucdb file to be converted to text only html with very few details

I played around with the merge command plus what ledi have posted and found a solution
I save each test coverage to a separate ucbd file
I then merge them into another ucdb file
then report that file into text
Code: 
 coverage save file1.ucdb
coverage save file2.ucdb
vcover merge merged.ucdb file1.ucdb file2.ucdb 
coverage report -file report.txt -byfile -detail -all -dump -fecanalysis -metricanalysis -option -assert -directive -cvg -codeAll

This produces a text report with details
note: merged.ucdb has to be created beforehand, so I just made it once with a random run and kept it for later
