vcoverage — Verilog/SystemC coverage analyzer

Synopsis

Create report:
   vcoverage -f input.vc <datafile>
Merge reports
   vcoverage --noreport -write <merged.dat>  <datafiles>

Description

Vcoverage reads the specified data file and generates annotated source code with coverage metrics annotated. By default logs/coverage.pl is read. If multiple coverage points exist on the same line, additional lines will be inserted to report the additional points.

Additional Verilog-standard arguments specify the search paths necessary to find the source code that the coverage analysis was performed on.

To get correct coverage percentages, you may wish to read logs/coverage.pl into Emacs and do a M-x keep-lines to include only those statistics of interest.

For Verilog conditions that should never occur, you should add a $stop statement. This will remove the coverage during the next build.

Arguments

--all-files
Specifies all files should be shown. By default, only those source files which have low coverage are written to the output directory.
--help
Displays this message and program version and exits.
--min count
Specifies the minimum occurrence count that should be flagged if the coverage point does not include a specified threshold. Defaults to 10.
--noreport
Don't produce output files. Used with --write to merge files.
--o output_directory
Sprcifies the directory name that source files with annotated coverage data should be written to.
--unlink
When using --write to combine coverage data, unlink all input files after the output has been created.
--version
Displays program version and exits.
--write filename
Specifies the aggregate coverage results, summed across all the files, should be written to the given filename. This is useful in scripts to combine many sequential runs into one master coverage file.

Verilog Arguments

The following arguments are compatible with GCC, VCS and most Verilog programs.

+libext+ext+ext...
Defines the extensions for Verilog files.
+define+var+value =item -Dvar=value
Defines the given variable.
+incdir+dir =item -Idir
Specifies a directory for finding include files.
-f file
Specifies a file containing additional command line arguments.
-y dir
Specifies a module search directory.
