Web13 de fev. de 2016 · 02-13-2016 05:55 PM. 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. shuttle bus international drive orlando
