While this will not directly answer your question...I strongly recommend downloading the mtline appNote from Cadence On-line Support.
The way you have your parameters in your netlist set up indicate that you would benefit from the information in this comprehensive appNote.

Your university will have a contact person whom you can contact to get the username and password. They can retrieve the document for you. In fact, there is a ton of good information on Cadence OnLine Support - you really need to get on there and browse. There are answers to many typical user questions.
Having said that, if you send me your email address, I'll forward the appNote to you since I'm the author.
