I recommend to use *.bdf file as top-level entity in your project.

This visual approach is convenient because you can represent all your own VHDL-modules and megafunctions created by megawizards as symbol modules in top-level entity.

So, it won't be necessary to deal with code generated by ALTPLL megawizard.

You need to configure your ALTPLL instance in megawizard properly and then connect I/O ports of ALTPLL with other ports of symbol modules in top-level entity.

P.S. To create symbol of your VHDL-module select "File -> Create/Update -> Create Symbol Files for Current File".

Then you can insert your symbol in top-level entity by "Symbol Tool" button.
