Usage message for vl lint.
Value:
"
vl lint: A linting tool for Verilog. Scans your Verilog files for things
that look like bugs (size mismatches, unused wires, etc.)
Example: vl lint engine.v wrapper.v core.v \\
--search ./simlibs \\
--search ./baselibs
Usage: vl lint [OPTIONS] file.v [file2.v ...]
Options:
-h,--help Show a brief usage message and exit.
--readme Show a more elaborate README and exit.
-s,--search=DIR Control the search path for finding modules.
You can give this switch multiple times, to
set up multiple search paths in priority
order.
--searchext=EXT Control the search extensions for finding
modules. You can give this switch multiple
times. By default we just look for files
named \"foo.v\" in the --search directories.
But if you have Verilog files with different
extensions, this won't work, so you can add
these extensions here. EXT should not
include the period, e.g., use \"--searchext
vv\" to consider files like \"foo.vv\", etc.
-I,--incdir=DIR Control the list of directories for `include
files. You can give this switch multiple
times. By default, we look only in the
current directory.
--topmod=MOD Limit the scope of the report to MOD. By
default we include all warnings for any
module we encounter. But if you say
\"--topmod foo\", we suppress all warnings for
modules that foo does not depend on. You can
give this switch multiple times, e.g.,
\"--topmod foo --topmod bar\" means: only show
warnings for foo, bar, and modules that they
depend on.
-q,--quiet=MOD Suppress all warnings that about MOD. You
can give this switch multiple times, e.g.,
\"-q foo -q bar\" will hide the warnings about
modules foo and bar.
-d,--drop=MOD Delete MOD from the module hierarchy before
doing any linting at all. This is a gross
(but effective) way to work through any bugs
in the linter that are triggered by certain
modules. The dropped modules are removed
from the module list without destroying
modules above them. This may occasionally
lead to false warnings about the modules
above (e.g., it may think some wires are
unused, because the module that uses them has
been removed.)
-i,--ignore=TYPE Ignore warnings of this TYPE. For instance,
\"--ignore oddexpr\" will suppress
VL_WARN_ODDEXPR warnings. Note that there
are much finer-grained ways to suppress
warnings; see \"vl lint --readme\" for more
information.
--cclimit=N Limit for the const check. This is a beta
feature that is not yet released. Setting N
to 0 (the default) disables the check.
Otherwise, limit the scope of the check to at
most N sub-expressions.
--edition=EDITION Which edition of the Verilog standard to
implement? Default: \"SystemVerilog\" (IEEE
1800-2012). You can alternately use
\"Verilog\" for IEEE 1364-2005, i.e.,
Verilog-2005.
--strict Disable VL extensions to Verilog.
-m,--mem=GB How much memory to try to use. Default: 4
GB. Raising this may improve performance by
avoiding garbage collection. To avoid
swapping, keep this below (physical_memory -
2 GB).
--debug Print extra information for debugging.
