I am getting the error 12006 when i try to compile this code and cant see whats wrong with it can anyone help please?
library ieee; use ieee.std_logic_1164.all; entity mux2_1_struct is port ( s,c,p : in std_logic; m : out std_logic) ; end mux2_1_struct; architecture struct of mux2_1_struct is component and_mux is port ( x,y : in std_logic; f : out std_logic); end component; component or_mux is port (x,y : in std_logic; f : out std_logic); end component; component not_mux is port( x : in std_logic; f : out std_logic); end component; signal n1,n2,n3 : std_logic; begin and_mux1 : and_mux port map ( x => c , y => n3 , f => n1); and_mux2: and_mux port map ( x => s , y => p , f => n2); not_mux1 : not_mux port map ( x => s , f => n3 ); or_mux1 : or_mux port map ( x => n1 , y => n2 , f => m); end struct; The error messages im getting are Error (12006): Node instance "and_mux2" instantiates undefined entity "and_mux". Ensure that required library paths are specified correctly, define the specified entity, or change the instantiation. If this entity represents Intel FPGA or third-party IP, generate the synthesis files for the IP.Link Copied

Have you added the source code for "and_mux" to the project?

I dont think so , is the source code for and_mux not in the architecture? or do i have to create it in another file?

You have a component declaration, but you need an entity and architecture (likely in another file) that define the behaviour.

Hi
I am also getting similar error when i tried to use the UART IP in my project. Kindly suggest some steps to overcome the issue please.
Error as folllows
Error (12006): Node instance "comb_3" instantiates undefined entity "Altera_UART_16550". Ensure that required library paths are specified correctly, define the specified entity, or change the instantiation. If this entity represents Intel FPGA or third-party IP, generate the synthesis files for the IP.
