<Warning message>
Warning (16067): <xxx> out of <xxx> DSP blocks in the design are not fully utilizing recommended internal DSP register banks.

Category: DSP
Tools: Quartus® Prime
Device: Arria® 10


Performance may be limited due to design not using internal register banks.

Since the DSP block is configured to maximize performance with the assumed number of pipeline stages, the tool cannot insert a pipeline by changing the user's design.
As the message suggests, performance may be improved by reviewing the design configuration.
