First time i am working with the design using Ethernet (Wiznet W5300). So i need your help from guys. Initially i have taken the exercise that I need run the 8-bit counter in NIOS using W5300.
Counter code as below
module counter
#(parameter WIDTH=8)
(
input clk, enable, rst_n,
output reg [WIDTH-1:0] count
);
always @ (posedge clk or negedge rst_n)
begin
if (~rst_n)
count <= 0;
else if (enable == 1'b1)
count <= count + 1;
end
endmoduleMain Function:
library ieee;
use ieee.std_logic_1164.all;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;
entity Instanstation is
port
(
count : out std_logic_vector(7 downto 0); -- 120 will be direct , group (T) 8 will be TTL
enable : in std_logic;
clk : in std_logic
);
end Instanstation;
architecture behav of Instanstation is
signal WD_nRSTs : std_logic;
signal RPC_OUT_AUX : std_logic_vector(7 downto 0);
component counter is
port
(
clk : in std_logic; -- 120 will be direct , group (T) 8 will be TTL
enable : in std_logic;
rst_n : in std_logic;
count : out std_logic_vector (7 downto 0));
end component;
begin
count(7 downto 0) <= RPC_OUT_AUX(7 downto 0);
end behav;Can anyone suggest me whether my design flow is right or wrong. Then how to interface the NIOS and WIZNET.
