Unified Coverage Reporting
The db based coverage reporting has been replaced by the Unified
Report Generator (URG). The URG generates combined reports for
all types of coverage information. The reports may be viewed through
through an overall summary "dashboard" for the entire design/
testbench.
The format of the text report generated by the URG is enhanced and
different from the text report that used to be generated by the vcs
-cov_report command line options. Any scripts that use these old
command line options now need to be modified to use the URG
options.
The functional coverage database files and their location have been
changed. The coverage database is written to a top-level coverage
directory. By default this directory name is simv.vdb. In general its
name comes from the name of the executable file, with the .vdb
extension. The reporting tool shipped with VCS version 2006.06
cannot read coverage databases generated using previous versions
of VCS. Similarly, the reporting tool shipped with VCS 2006.06
versions cannot read coverage databases generated using VCS
2006.06.
