Error

I have some problems when I try to compile mymux. This is my code: 

LIBRARY ieee ; 

USE ieee.std_logic_1164.all ; 

Entity mymux21 is 

port (A,B: in std_logic_vector (3 downto 0); 

S: in std_logic; 

F: out std_logic_vector (3 downto 0)); 

end mymux21; 

Architecture behave of mymux21 is 

begin 

F <= A when (S = '0') else B; 

end behave; 

Architecture struct of mymux21 is 

component mymux21 is 

port (A,B,S: in std_logic; 

F: out std_logic); 

end component; 

begin  

Copy1: mymux21 port map (A => A(0), B => B(0), S => S, F => F(0)); 

Copy2: mymux21 port map (A => A(1), B => B(1), S => S, F => F(1)); 

Copy3: mymux21 port map (A => A(2), B => B(2), S => S, F => F(2)); 

Copy4: mymux21 port map (A => A(3), B => B(3), S => S, F => F(3)); 

end struct; 

 

and the error is: "project too complex: hierarchy path is too long"

The error message isn't related to your code.

The error is your project is too complex and the heirarchy is too large. I assume you have layers and layers of code. To fix it - have less layers

The problem could be the code. You are creating an architecture that instantiates itself, possibly creating an infinite loop. You should use different names for the std_logic and std_logic_vector versions of your mux.

I suggest you try Long path tool is the very good program for easily delete, copy & rename long path files, error, unlock solution.
Try it and solve your problem.
