Digital logic synthesis-an overview

In today´s highly competitive market, system designers are faced with the conflicting challenges of greater system complexity and the need for short, efficient design cycles. These complexity and time-to-market pressures continue to reshape the art of designing electronic systems, and have led to the emergence and growing acceptance of top-down design methodologies. With top-down design, engineers start work at a higher-level of abstraction than with traditional, gate-level design techniques. The designer manipulates logical or functional abstractions, and uses logic synthesis tools to produce the gate-level implementation
