Coverage analysis in VCs

The VCS can also collect coverage Metric during the simulation process. Where coverage types are:

1) Code Coverage: Includes Control_flow and value two parts of Coverage,line_coverage, Branch_coverage, Toggle_coverage,

Fsm_coverage.

2) Functional Coverage: Includes Covergroup,sva.

Coverage database generation: Contains all the information about coverage, which is placed by default in the Simv.vdb folder.

In the compile command: vcs [cover_options] [compile_options] source.v

[Cover_options] can be:-cm Line+cond+tgl+fsm+branch+assert

-cm_dir Change the location of the Simv.vdb folder. -CM_NAME specifies testname.

During the simulation: SIMV [cover_options] [run_options]

[Cover_options] can be:-cm Line+cond+tgl+fsm+branch+assert

[Run_options] Specifies the runtime options.

The production of Coverage reports:

Use the tool Urg (Unified report Generator) to produce HTML-formatted files.

Urg-dir Dir1 [Urg_option]

Use the GUI interface of DVE.

Dve-cov-dir <simv.vdb>
