Hi,

Because I am a beginner in VHDL, I am constantly having trouble writing code.

I designed a simple counter and tested it. It works how it should, but when I use this component elsewhere it doesn't work properly, in fact it doesn't work at all.

This is the way I used the component:

Code:
entity Nalfa is
    generic (M:integer:=8);
    port (CLK: in bit;
            Reset: in bit;
            q:out std_logic_vector (M/2-1 downto 0));
end Nalfa;


architecture Behavioral of Nalfa is    

-- unimportant code

component Counter is      
    generic (N:integer);
    port (Clk: in bit;
    reset: in bit;
    ce: in bit;
    load: in bit;
    dir: in bit;
    din:in std_logic_vector(N-1 downto 0);
    count: out std_logic_vector (N-1 downto 0));
end component;    

signal aux1: std_logic_vector (m/2-1 downto 0 ):=(others=>'0');
signal count1: std_logic_vector (m/2-1 downto 0 );

begin    
    
    L1: Counter generic  map (N => (M/2))
    port map (Clk,Reset,ce=>'1',load=>Reset,dir=>'1',din=>aux1,count=>count1);     

    -- unimportant code

    L2: q<=count1;


end Behavioral;
Can you please tell me where is the mistake?
