h1. Command Line Options

Verilog Translator handles the following command line options:

|*Long name*|*Short name*|*Description*|*Default value, if applicable*|
|--include-path|-I|Include directories|-|
|--library-file|-L|Library file|-|

h2. Include directories

The option sets the directories where VeriTrans searches for Verilog files included from others. Multiple paths are separated by @:@ (for Unix) or @;@ (for Windows).

When @a.v@ uses something defined in @b.v@ (located at @/absolute/path/to@), there may be the following situations:
* @a.v@ does not contain @`include "b.v"@:
** both files should be given to VeriTrans;
** @b.v@ comes first;
** @--include-path@ is not required;
* @a.v@ contains @`include "b.v"@:
** the path @/absolute/path/to@ should be added to @--include-path@;
* @a.v@ contains @`include "path/to/b.v"@:
** the path @/absolute/path/to@ @/absolute@ should be added to @--include-path@.

h2. Library file

The option sets the library file that declares names of non-standard system tasks and functions. The file has the following structure:

<pre>
<kind> (<type>)? <name>
...
<kind> (<type>)? <name>
</pre>

where
* @<kind>@ is either @function@ or @task@;
* @<type>@ is the return type (only for functions);
* @<name>@ is the entity name.

Here is an example:

<pre>
function [3:0] $myFunction
task $myTask
</pre>
