altdpram Megafunction

Parameterized dual-port RAM megafunction. The altdpram megafunction can be used to implement the memory logic array block (MLAB), as well as the standard memory block types, in Stratix devices. Intel recommends instantiating this function with the IP Catalog. The altdpram megafunction is available for all supported Intel devices.

Note:

The IP Catalog calls altdpram only when the read address is asynchronous.
The Quartus^® Prime Compiler automatically implements this function in logic cells in MAX series devices. The altdpram function uses DFFE primitives or latch arrays in the MAXdevices.
You can use the Assignment Editor to add, change, or delete assignments and assignment values for megafunctions.
