hi, i just want to grate a 8 : 1 mux but i got this error: 10334 VHDL error at eight_1.vhd (11) : y is not subporgram, a type, or an array object

 library ieee;

use ieee.std_logic_1164.all;

entity eight_1 is

port(a:in std_logic_vector(7 downto 0); s: in std_logic_vector(2 downto 0); y: out

   std_logic);

 end eight_1;

 architecture d_f of eight_1 is 

 begin

 process(a,s)

 begin

 if s = "000" then y (0) <=a;

 elsif s = "001" then y (1) <=a;

 elsif s = "010" then y (2) <=a;

 elsif s = "011" then y (3) <=a;

 elsif s = "100" then y (4) <=a;

 elsif s = "101" then y (5) <=a;

 elsif s = "110" then y (6) <=a;

 else  y (7) <=a;

 end if;

end process;

Hi,

Replace all IF statement like if s = "000" then y (0) <=a; with if s = "000" then y <= a(7); since y is a one bit output.

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

 

Best Regards
