Description
In the Quartus® Prime software, you will see that your RAM is not inferred as MLABs if you have selected new data for read-during-write behaviour.
New data RDW is not supported for MLAB inference.
Resolution
To implement an MLAB RAM with new data RDW behaviour, use the IP Parameter Editor to create the RAM.
Support for inferring MLAB RAM with new data RDW behaviour is scheduled to be added to a future release of the Quartus Prime Pro edition software.
