Thanks for the suggestion, leon3-sis-cov works, with a minor error as:

error: copying tree (4):
/home/user45/quick-start/rtems/5/share/rtems/tester/covoar/covoar.css
-> /home/user45/quick-start/leon3-sis-coverage/score: [Errno 2] No
such file or directory:
'/home/user45/quick-start/rtems/5/share/rtems/tester/covoar/covoar.css'

But the leon3-sis-report.html gives the coverage report. I am still
studying the leon3-sis-coverage directory.

On a sidenote I see that you worked on this as your gsoc project.
Please mention any source which proved to be helpful in understanding
rtems better.
