Thats because you need the source code for the adder1 component, and it must be compiled before adder4. If you dont have VHDL source, you must use a component, as this tells the VHDL compiler what to expect. With direct instantiation instead of checking the component it uses the entity directly.

WebStudent Activity 3: Elaborating a 16-bit Adder With the previous elaborate command, you elaborated a 12-bit adder. However, we would like to synthesize a 16-bit adder. Instead of going back to the source Verilog file and changing the default value for the DATA WIDTH parameter, you could also use the following command to overwrite this parameter:
