Verilog Models

This isn't 100% a programming question, but I'm hoping someone can point me in the right direction. I'm playing around using an HDL for simulating projects. I do not know Verilog. The HDL I'm using has lots of gate primatives but the most elaborate part would be a MUX. I'm looking to find out if there is a database anywhere of pre-made common logic chips like the CD and 74HC families that I could copy the code or import.

Thanks.
