h1. HDL Testbench Simulation

To run HDL testbench on ModelSim simulator and collect the coverage data, do the following:

1. Copy @testbench_launch.sh@ script to the directory with HDL testbench.

2. Run the script with the following arguments:

<pre>

-f path-to-hdl-file-under-test -g

</pre>

3. On ModelSim press "Run All" button.

To generate an HTML report about test coverage at the GUI mode do the following:

1. Collect coverage information (create a coverage database for the specified test):

<pre>

coverage save -onexit -testname <testname> <cov_database.ucdb>

</pre>

2. Merge the produced database with the general one (after exit from ModelSim):

<pre>

vcover merge <cov_database.ucdb> <overall_database.ucdb> -o <overall_database.ucdb>

</pre>

3. Generate an HTML report:

<pre>

vcover report -html <overall_database.ucdb>

</pre>

To generate an HTML report about test coverage at command line mode run the @testbench_launch.sh@ script with the following parameters:

<pre>

-f path-to-hdl-file-under-test

</pre>

and then do:

<pre>

vcover report -html <overall_database.ucdb>

</pre>
