Getting Started
+notimingcheck
Suppresses timing check system tasks during compilation. This
option can moderately improve simulation performance. The
extent of this improvement depends on the number of timing
checks that VCS ignores.
-ntb
Enables the use of the OpenVera Testbench language constructs
described in the OpenVera Language Reference Manual: Native
Testbench.
-ova_file filename
Identifies an OVA file as input. This option is not required if the
OVA file name contains a .ova extension.
-P pli.tab
Compiles a user-defined PLI definition table file.
-PP
Compiles a VCD file for interactive debugging while minimizing
the amount of net data for fast post-processing.
-R
Runs the executable file immediately after VCS links it together.
You can add any runtime option to the vcs command line.
-RI
Compiles model for interactive use, invokes the VirSim graphical
user interface immediately after compilation, and pauses
simulation at time zero.
-s
Specifies stopping simulation, and entering the CLI interactive
mode, just as simulation begins. Use this option on the vcs
command line along with the -R and +cli options. The -s option
is also a runtime option on the simv command line.
