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.
