а эти все export

WRITEDATA : out STD_LOGIC_VECTOR(31 downto 0);
BE : out STD_LOGIC_VECTOR(3 downto 0);
WR : out STD_LOGIC;
RD : out STD_LOGIC;
READY : in STD_LOGIC;
READDATA : in STD_LOGIC_VECTOR(31 downto 0);
VALID : in STD_LOGIC;
CLOCK : out STD_LOGIC
и ниже текст:
CLOCK<=clk;
ADDRESS <= "00"&avs_s0_address;
WRITEDATA <= avs_s0_writedata;
WR <= avs_s0_write;
RD <= avs_s0_read;
avs_s0_waitrequest <= READY;
avs_s0_readdata <= READDATA;
avs_s0_readdatavalid <= not VALID;
