20.1.1.

From what you say, it appears they were removed from IP Catalog but left in the Megafunctons directory where I can still invoke them from Block Editor. However, I can't figure out how to parameterize them without the MegaWizard in IP Catalog. I read some Intel documentation on LPM_INV that recommended against using it and to use multiple primitive inverters instead. Can't figure this recommendation out as some of these basic LPMs would simplify my schematics considerably.

Regardless, sounds like the LPMs I'd like to use have been deprecated, and I don't what to invest time in designs that don't work or won't in the future.

As always, many thanks for your help!
