NAME

vhier - Return all files in a verilog hierarchy using Verilog::Netlist

CONTENTS

SYNOPSIS



  vhier --help
  vhier [verilog_options] [-o filename] [verilog_files.v...]



DESCRIPTION

Vhier reads the Verilog files passed on the command line and outputs a tree of all of the filenames, modules, and cells referenced by that file.

VERILOG ARGUMENTS

The following arguments are compatible with GCC, VCS and most Verilog programs.
+define+var+value =item -Dvar=value Defines the given preprocessor symbol.
-F file Read the specified file, and act as if all text inside it was specified as command line parameters. Any relative paths are relative to the directory containing the specified file.
-f file Read the specified file, and act as if all text inside it was specified as command line parameters. Any relative paths are relative to the current directory.
+incdir+dir =item -Idir Add the directory to the list of directories that should be searched for include directories or libraries.
+libext+ext+ext... Specify the extensions that should be used for finding modules. If for example module x is referenced, look in x.ext.
-sv Specifies SystemVerilog language features should be enabled; equivalent to --language 1800-2012. This option is selected by default, it exists for compatibility with other simulators.
-y dir Add the directory to the list of directories that should be searched for include directories or libraries.

VHIER ARGUMENTS

--help Displays this message and program version and exits.
--o file Use the given filename for output instead of stdout.
--cells Show the module name of all cells in top-down order.
--forest Show ASCII-art hierarchy tree of all cells (like ps --forest)
--input-files Show all input filenames. Copying all of these files should result in only those files needed to represent the entire design.
--instance With --cells or --forest, show module instance names.
--language <1364-1995|1364-2001|1364-2005|1800-2005|1800-2009|1800-2012> Set the language standard for the files. This determines which tokens are signals versus keywords, such as the ever-common do (data-out signal, versus a do-while loop keyword).
--resolve-files Show resolved filenames passed on the command line. This will convert raw module and filenames without paths to include the library search path directory. Output filenames will be in the same order as passed on the command line. Unlike --input-files or --module-files, hierarchy is not traversed.
--module-files Show all module filenames in top-down order. Child modules will always appear as low as possible, so that reversing the list will allow bottom-up processing of modules. Unlike input-files, header files are not included.
--modules Show all module names.
--nomissing Do not complain about references to missing modules.
--missing-modules With --nomissing, show all modules that are not found.
--synthesis Define SYNTHESIS, and ignore text bewteen ambit, pragma, synopsys or synthesis translate_off and translate_on meta comments. Note using metacomments is discouraged as they have led to silicon bugs (versus ifdef SYNTHESIS); see <http://www.veripool.org/papers/TenIPEdits_SNUGBos07_paper.pdf>.
--top-module module Start the report at the specified module name, ignoring all modules that are not the one specified with --top-module or below, and report an error if the --top-module specified does not exist. Without this option vhier will report all modules, starting at the module(s) that have no children below them.

Note this option will not change the result of the --input-files list, as the files needed to parse any design are independent of which modules are used.

--version Displays program version and exits.
--xml Create output in XML format.
