Thanks Tricky; The email address of the authors donot work.....Jshmalet is the author and hence I am trying to approach him. Also the top level module is missing

Generally I never trust anything from OpenCores.

I have found stuff to lack documentation, have poor coding styles and as you have found, missing modules.

If you need support you are reliant on the original author, who may not have worked on it for a long time, or not be interested.

Generally, use at your own peril.
