Thanks toolic,appreciate your help.the information was very useful.
I am trying to do the following
a)open the files in a given directory/subdirectories-only files with extension .v/.vh/.svn/.sv/.svi. At present concentrating on only .v and .vh
b)search for verilog module definition
c)for each module that is defined more than once the list of all files(full path /relative path) in which the module is defined should be printed.
d)must be able to exclude // from parsing
i figured out i could do much of the stuff using o the vhier,but i am unsure of how to use the verilog arguments like
1.+incdir+dir =item -Idir
Add the directory to the list of directories that should be searched for include directories or libraries.
2.and also the vhier -f file:Read the specified file, and act as if all text inside it was specified as command line parameters.
Should a filehandle be passed or just the filename?
I know this sounds really silly asking such basic questions but I am good at writing perl code rather than using packages
Would appreciate if you could throw some light on this.
Thanks

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
