debugging in ns2
 

I am trying to develop a new routing protocol in ns2. Although i have given a command in tcl file that should be called from command function present in .cc file. But it is not doing so.
Could we debug this and find the point where is the problem. If yes then how ?

I have heard that there are debuggers in ns2 . But this is for tcl or c++ ....
Could any one please help me ... How can i proceed further.

Thanks for ur help
