How to use Quartus Block editor Megafunctions

More:

My problem appears more fundamental. I looked at IP Catalog and traced some IP examples from the list back to their directory; it’s Megafunctions, i.e., exactly where I’m trying to access such as LPM_INV and other simple elements.

However, although LPM_INV is in the Megafunctions directory, it doesn’t show up in IP Catalog even when I filter for All Device Families. I verified its absence with search. Further, I can include LPM_INV in my schematic and get a successful compile.

I’m using a DE10-Nano with Cyclone V.

Any idea what’s going on?

Thanks,
