Simulation Options
-cm_name filename
As a compile-time or runtime option, specifies the name of the
intermediate data files. On the cmView command line, specifies
the name of the report files.
-cm_tglfile filename
Specifies displaying a total toggle count at runtime for one or more
subhierarchies specified by the top-level module instance entered
in the file. This option is also a compile-time option.
Options for Enabling and Disabling Specify Blocks
+no_notifier
Suppresses the toggling of notifier registers that are optional
arguments of system timing checks. The reporting of timing check
violations is not affected. This is also a compile-time option.
+no_tchk_msg
Disables the display of timing violations but does not disable the
toggling of notifier registers in timing checks. This is also a
compile-time option.
+notimingcheck
Disables timing check system tasks in your design. Using this
option at runtime can improve the simulation performance of your
design, depending on the number of timing checks that this option
disables.
You can also use this option at compile time. Using this option at
compile time tells VCS to ignore timing checks when it compiles
your design so that the timing checks are not compiled into the
executable. This results in a faster simulating executable than one
that includes timing checks, which are disabled by this option at
runtime.
