VHDL Code for 4-Bit Up-Counter:
library ieee;
use ieee.std_logic_1164.all;
use ieee.std_logic_unsigned.all;
entity vhdl_binary_counter is
port(C, CLR : in std_logic;
Q : out std_logic_vector(3 downto 0));
end vhdl_binary_counter;
architecture bhv of vhdl_binary_counter is
signal tmp: std_logic_vector(3 downto 0);
begin
process (C, CLR)
begin
if (CLR=’1′) then
tmp <= "0000";
elsif (C’event and C=’1′) then
tmp <= tmp + 1;
end if;
end process;
Q <= tmp;
end bhv;
