I'm basically done with this project, but it's the first time we are required to input a clock signal. I usually do it in the vector waveform file, but doing it as an input I don't understand how I go about it. I tried putting it in my input signal list as shown:
entity ForBack is
port (
F_B : in std_logic;
Clk : in std_logic;
Q : inout std_logic_vector (2 to 0);
D0 : out std_logic;
D1 : out std_logic;
D2 : out std_logic
);
end ForBack;
and then I declare it in the port map for one of my D Flip Flops as:
U0: D_flip_flop port map(D=>D(0),Clk=>Clock,Q=>Q(0),Qnot=>QN(0));
And Altera is giving me the error that "Formal "Clk" does not exist."
Can anyone see an obvious mistake here? I tried googling the error, but nothing showed.
Thanks guys.
