Performance Driven Layout and Synthesis 65 Functional Decomposition of Speed Optimized Circuits

Abstract. There are two ways to design a digital circuit. Covering methods are widely used which includes several speed- or area-optimizing steps. We will show, that decomposition is a profound way to design logical circuits yielding short delay times, low power consumption and a little amount of chip area. This paper provides some new ideas and algorithms to decompose logical functions in order to achieve a high speed of the designed circuit.
