lpm_ram_io Megafunction
Parameterized RAM with a single I/O
port megafunction. This megafunction is provided only for backward
compatibility; instead, Intel recommends using the
altsyncram
megafunction. The
lpm_ram_io
function uses Embedded System Blocks
(ESBs) in some obsoleted devices, Embedded Array Blocks (EABs) in other obsoleted
devices, or DFFE
primitives or latch arrays in
MAX3000 and MAX7000 devices or if the
USE_EAB
parameter set to "OFF"
. Intel
strongly recommends using synchronous rather than asynchronous RAM
functions.
- The Compiler automatically implements this function in logic cells in MAX3000 and MAX7000 devices.
- You can use the Assignment Editor to add, change, or delete assignments and assignment values for megafunctions.
