Object-oriented high-level modeling of system components for the generation of VHDL code

This paper describes a method for the design of digital systems that automatically derives an executable prototype of a system from an informal specification. Our method bases on an object-oriented hierarchy of classes which describe the functions of components. A tree of instances of these classes representing a certain system is built depending on the specification. VHDL descriptions of all classes involved in this tree are transformed into VHDL code for the complete system. Our approach emphasizes a bottom-lip procedure and reuse of existing components.
