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.
Note: More information is available on the RAM megafunctions on the Altera website.
