To generate an HTML report about test coverage at the GUI mode do the following:
15
16
1. Collect coverage information:
17
<pre>
18
coverage save -onexit -testname <testname> <cov_database.ucdb> - создает базу с покрытием для теста <testname>.
19
</pre>
20
2. Merge the produced database with the general one (after exit from ModelSim):
21
<pre>
22
vcover merge <cov_database.ucdb> <overall_database.ucdb> -o <overall_database.ucdb>
23
</pre>
24
3. Generate an HTML report:
25
<pre>
26
vcover report -html <overall_database.ucdb>
27
</pre>
28

To generate an HTML report about test coverage at command line mode run the @testbench_launch.sh@ script with the following parameters:
30
<pre>
31
-f path-to-hdl-file-under-test
32
</pre>
33
and then do:
34
<pre>
35
vcover report -html <overall_database.ucdb>
36
