A method includes synthesizing a hardware description language (HDL) code into a netlist comprising a first a second and a third components. The method further includes allocating addresses to each component of the netlist. Each allocated address includes assigned addresses and unassigned addresses. An internal address space for a chip is formed based on the allocated addresses. The internal address space includes assigned addresses followed by unassigned addresses for the first component concatenated to the assigned addresses followed by unassigned addresses for the second component concatenated to the assigned addresses followed by unassigned addresses for the third component. An external address space for components outside of the chip is generated that includes only the assigned addresses of the first component concatenated to the assigned addresses of the second component concatenated to the assigned addresses of the third component. Internal addresses are translated to external addresses and vice versa.
