Use the block RAM by instantiating it in the VHDL code:

Code VHDL - [expand]
1
2
3

5
6
7
8
9
10
11
12

-- Block SelectRAM Instantiation
U_RAMB16_S36: RAMB16_S36
port map (
DI => DATA_IN (31 downto 0), -- insert 32 bits data-in bus (<31 downto 0>)
DIP => DATA_IN (35 downto 32), -- insert 4 bits parity data-in bus (or <35 downto 32>)
ADDR => ADDRESS (8 downto 0), -- insert 9 bits address bus
EN => ENABLE, -- insert enable signal
WE => WRITE_EN, -- insert write enable signal
SSR => INV_SET_RESET, -- insert set/reset signal
CLK => CLK_BUFG, -- insert clock signal
DO => DATA_OUT (31 downto 0), -- insert 32 bits data-out bus (<31 downto 0>)
DOP => DATA_OUT (35 downto 32) -- insert 4 bits parity data-out bus (or <35 downto 32>)
);
