Noise Pollution

Example : 4 bit Johnson Counter with testbench A Johnson act is a digital roach which consists of a series of deputise flops connected to subscribe toher in a feedback manner.The hitch is unembellished type of shift register where the complement let onput of the stop point flipflop is fed back to the input of first flipflop.This is intimately mistakable to ring counter with a few extra advantages.When the circle is reset all the flipflop outputs are made zero. For n-flipflop Johnson counter we ball up up a MOD-2n counter. That means the counter has 2n different states. The circuit diagram for a 3 bit Johnson counter is shown to a lower place: library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.NUMERIC_STD.ALL; entity johnson_counter is port (         DAT_O : out unsigned(3 downto 0);         RST_I : in std_logic;         CLK_I : in std_logic         ); end johnson_counter; architecture Behavioral of johnson_counter is orient temporary : unsigned(3 downto 0):=(others => 0); begin DAT_O <= temp; sue(CLK_I) begin     if( rising_edge(CLK_I) ) accordingly         if (RST_I = 1) then             temp <= (others => 0);         else             temp(1) <= temp(0);             temp(2) <= temp(1);             temp(3) <= temp(2);             temp(0) <= not temp(3);         end if;     end if; end crop;     end Behavioral; The testbench code used for testing the learn is given below: LIBRARY ieee; USE ieee.std_logic_1164.ALL; USE ieee.numeric_std.ALL; ENTITY tb2 IS stopping point tb2; ARCHITECTURE behavior OF tb2 IS    --Inputs    signal RST_I : std_logic := 0;    signal CLK_I : std_logic := 0;     --Outputs    signal DAT_O : unsigned(3 downto 0);    -- clock period definitions    constant CLK_I_period : time := 1 ns; BEGIN     -- represent the unit Under Test (UUT)     uut: entity work.johnson_counter PORT MA!
