1 Digital System Design

The most complicated stage of each design, namely the system design, is discussed. An example of the design for a rather simple processor is shown. A design procedure is proposed, which included such steps as combination of separate algorithmic state machines (ASM); synthesis of data-path; control unit design, and composition of data-path and control unit into whole processor. The main advantage of proposed procedure is formalization of the design process, where all steps are formalized and automated in EDA tool “Abelite” designed by the author of this chapter.
