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.
