Hello,
I want to use FIFO component in vhdl. I have successfully designed FIFO component and it is working fine, i have tested it with testbench. But the problem is i don't know how to use this component in vhdl code.
Here is description of work i want to do. I have another component named ALU, one instantiation of it will write data into FIFO(PUSH) and other will read data from FIFO(POP). The code is

Code:
[b]library ieee;
use ieee.std_logic_1164.all;

entity exam3 is 
	generic (	B: natural:=8; -- number of data bits
				W: natural:=2 -- number of address bits
			);
	port(v10: in std_logic_vector(7 downto 0);
		 clk: in std_logic;
		 v40: out std_logic_vector(7 downto 0));
end exam3;

architecture structure of exam3 is 

	component alu is 
	port(a,b:in std_logic_vector(7 downto 0);
		clk:in std_logic;
		sel:in std_logic_vector(2 downto 0) ;
		c: out std_logic_vector(7 downto 0));
	end component;
	component fifo
	generic (B : natural;W:natural);
	port (	clk: in std_logic;
			rd, wr: in std_logic;
			w_data: in std_logic_vector ( B-1 downto 0) ;
			empty, full: out std_logic ;
			r_data : out std_logic_vector ( B-1 downto 0));
	end component;
	
	signal rd,wr,s_empty,s_full: std_logic;
	signal v4,v5: std_logic_vector(7 downto 0);
	begin
		 u3: alu port map(v10, v5,clk,"101",v40); --xor
		
		u_fifo:fifo
		generic map(B=>B,W=>W)
		port map(clk=>clk,rd=>rd,wr=>wr,
						w_data=>v4,empty=>s_empty,full=>s_full,r_data=>v5); 

		 u2: alu port map(v10, "11111111",clk,"001",v4); --and
end structure;
[/b]
May be this is basic question but as i am new to VHDL, so i can't understand how to solve it. I will be thankful to you for your help.
 

Re: using FIFO in vhdl

hi
i am new at vhdl too!!
