INFER_RAMS_FROM_RAW_LOGIC
Instructs the Compiler to infer RAM from registers and multiplexers. Some HDL patterns that differ from
Altera RAM templates are initially converted into logic. However, these structures function as RAM and,
because of that, the Compiler may create an altsyncram megafunction instance for them at a later stage
when this assignment is on. With this assignment is turned on, the Compiler may use more device RAM
resources and less LABs.
Type
Boolean
Device Support
This setting can be used in projects targeting any Altera device family.
Notes
