Designing with Low-Level Primitives User Guide, Version 3.0
Section 2, Primitive Reference, shows a list of primitives with note 1 stating these are only supported in Stratix® III and Cyclone® III devices. This is not accurate; the following primitives are only supported in Cyclone III devices:
- ALT_OUTBUF_TRI_DIFF
- ALT_IOBUF_DIFF
- ALT_BIDIR_DIFF
