I want to know is there any tools which show me a graphical presentation of codes? Better to describe my case I run wpan_demo1.tcl on ns2.35 from thisi directory /home/alex/Downloads/ns-allinone-2.35/ns-2.35/tcl/ex/wpan. As you see by ruuning this scrpt lots of file on the "/home/alex/Downloads/ns-allinone-2.35/ns-2.35/wpan" will run. I want to know is there any tool which depict the relations between this file or in each file what the funstion is and show the relation between funstions?
I search and got information about Doxygen and Grephviz but not sure and do not know how to.

$ ns wpan_demo1.tcl :
1) The nam simulation opens OK. Press the 'Play' button for animation.
2) The files wpan_demo1.nam (2.3MB) and wpan_demo1.tr (1.7MB) are created.
? What more can you want ?

( Doxygen sorts out any documentation written into {source files .c, .cc, etc.}.
Not a visualizer.)

To know "relations between functions" :
I guess you will have to learn c++ and tcl + otcl, and the particular ns2 functions,
so you can read the code to see what's happening.

Thanks,dear knudfl thanks for replying again.
I am looking for tools which visualize the code. I need a tools to visualize in order to make my work faster. But what you told is right but what I am looking for is a code presenter. I think this link ask my question better than my I asked http://stackoverflow.com/questions/517589/tools-to-get-a-pictorial-function-call-graph-of-code based on this I found codeviz and understant. My question is: do you have any experience with those or something like them ? Suppose that you give me 10 file each one 400 line of project If I have one these tools my work become so faster than my self track all line to see what is happening ?

Sorry, I am not a coder, and cannot come up with any good advices.

The Graphviz image shown here looks promising http://www.graphviz.org/
* http://www.graphviz.org/Documentation.php

Looks even better : Codeviz http://www.csn.ul.ie/~mel/projects/codeviz/
... and there is good documentation for both tools Graphviz / Codeviz, I think.
So why not go ahead and try out both the applications ...
