*.qip and *.vhd Mega Wizard files

Hi,

In my project I’m using Mega Wizard Plug-In manager custom variation (LPM_ADD_SUB).

When finished, several files are appearing: *.qip and below that, the *.vhd file (project navigator under Files).

If I want to copy the upper architecture to another project, do I need to copy the *.qip file too or the *.vhd would be enough? (or maybe I need to create the whole custom variation from the start on my new project)
